Mobile security full guide

Mobile Security
Mobile Security – Introduction
In this tutorial, we will deal with mobile security concepts mostly from the
practical point of view. Take a look at the following graph, it illustrates the
ever-growing number of mobile phone users across the world, which brings
out the importance of mobile security.

The estimated number of mobile devices is around 5.8 billion, which is
thought to have grown exponentially within five years and is supposed to
reach nearly 12 billion within four years. Hence, it will be an average of two
mobile devices per person on the planet. This makes us fully dependent on
mobile devices with our sensitive data being transported all over. As a result,
mobile security is one of the most important concepts to take in

Mobile Security as a concept deals with the protection of our mobile devices
from possible attacks by other mobile devices, or the wireless environment
that the device is connected to.
Following are the major threats regarding mobile security −

Loss of mobile device. This is a common issue that can put at risk not only you
but even your contacts by possible phishing.

Application hacking or breaching. This is the second most important issue. Many
of us have downloaded and installed phone applications. Some of them request
extra access or privileges such as access to your location, contact, browsing
history for marketing purposes, but on the other hand, the site provides access
to other contacts too. Other factors of concern are Trojans, viruses, etc.

Smartphone theft is a common problem for owners of highly coveted smartphones
such as iPhone or Android devices. The danger of corporate data, such as account
credentials and access to email falling into the hands of a tech thief is a threat.

Mobile Security – Attack Vectors
By definition, an Attack Vector is a method or technique that a hacker uses
to gain access to another computing device or network in order to inject a
“bad code” often called payload. This vector helps hackers to exploit system
vulnerabilities. Many of these attack vectors take advantage of the human
element as it is the weakest point of this system. Following is the schematic
representation of the attack vectors process which can be many at the same
time used by a hacker.

Some of the mobile attack vectors are −

o Virus and Rootkit
o Application modification
o OS modification

Data Exfiltration
o Data leaves the organization
o Print screen
o Copy to USB and backup loss

Data Tampering
o Modification by another application
o Undetected tamper attempts
o Jail-broken devices

Data Loss
o Device loss
o Unauthorized device access
o Application vulnerabilities

Consequences of Attack Vectors
Attack vectors is the hacking process as explained and it is successful,
following is the impact on your mobile devices.

Losing your data − If your mobile device has been hacked, or a virus introduced,
then all your stored data is lost and taken by the attacker.

Bad use of your mobile resources − Which means that your network or mobile
device can go in overload so you are unable to access your genuine services. In
worse scenarios, to be used by the hacker to attach another machine or network.

Reputation loss − In case your Facebook account or business email account is
hacked, the hacker can send fake messages to your friends, business partners
and other contacts. This might damage your reputation.

Identity theft − There can be a case of identity theft such as photo, name,
address, credit card, etc. and the same can be used for a crime.

Anatomy of a Mobile Attack
Following is a schematic representation of the anatomy of a mobile attack. It
starts with the infection phase which includes attack vectors.

Infecting the device
Infecting the device with mobile spyware is performed differently for Android
and iOS devices.
Android − Users are tricked to download an app from the market or from a
third-party application generally by using social engineering attack. Remote
infection can also be performed through a Man-in-the-Middle (MitM) attack,
where an active adversary intercepts the user’s mobile communications to
inject the malware.
iOS − iOS infection requires physical access to the mobile. Infecting the
device can also be through exploiting a zero-day such as the JailbreakME

Installing a backdoor
To install a backdoor requires administrator privileges by rooting Android
devices and jailbreaking Apple devices. Despite device manufacturers placing
rooting/jailbreaking detection mechanisms, mobile spyware easily bypasses
them −
Android − Rooting detection mechanisms do not apply to intentional rooting.
iOS − The jailbreaking “community” is vociferous and motivated.

Bypassing encryption mechanisms and exfiltrating

Spyware sends mobile content such as encrypted emails and messages to
the attacker servers in plain text. The spyware does not directly attack the
secure container. It grabs the data at the point where the user pulls up data
from the secure container in order to read it. At that stage, when the content
is decrypted for the user’s usage, the spyware takes controls of the content
and sends it on.

How Can a Hacker Profit from a Successfully Compromised
In most cases most of us think what can we possibly lose in case our mobile
is hacked. The answer is simple – we will lose our privacy. Our device will
become a surveillance system for the hacker to observer us. Other activities
of profit for the hacker is to take our sensitive data, make payments, carry
out illegal activities like DDoS attacks. Following is a schematic

OWASP Mobile Top 10 Risks
When talking about mobile security, we base the vulnerability types on
OWASP which is a not-for-profit charitable organization in the United States,

established on April 21. OWASP is an international organization and the
OWASP Foundation supports OWASP efforts around the world.
For mobile devices, OWASP has 10 vulnerability classifications.

M1-Improper Platform Usage
This category covers the misuse of a platform feature or the failure to use
platform security controls. It might include Android intents, platform
permissions, misuse of TouchID, the Keychain, or some other security control
that is part of the mobile operating system. There are several ways that
mobile apps can experience this risk.

M2-Insecure Data
This new category is a combination of M2 and M4 from Mobile Top Ten 2014.
This covers insecure data storage and unintended data leakage.

M3-Insecure Communication
This covers poor handshaking, incorrect SSL versions, weak negotiation, clear
text communication of sensitive assets, etc.

M4-Insecure Authentication
This category captures the notions of authenticating the end user or bad
session management. This includes −

Failing to identify the user at all when that should be required

Failure to maintain the user’s identity when it is required

Weaknesses in session management

M5-Insuficient Cryptography
The code applies cryptography to a sensitive information asset. However, the
cryptography is insufficient in some way. Note that anything and everything
related to TLS or SSL goes in M3. Also, if the app fails to use cryptography at
all when it should, that probably belongs in M2. This category is for issues
where cryptography was attempted, but it wasn’t done correctly.

M6-Insecure Authorization
This is a category to capture any failures in authorization (e.g., authorization
decisions in the client side, forced browsing, etc.) It is distinct from
authentication issues (e.g., device enrolment, user identification, etc.)

If the app does not authenticate the users at all in a situation where it should
(e.g., granting anonymous access to some resource or service when
authenticated and authorized access is required), then that is an
authentication failure not an authorization failure.

M7-Client Code Quality
This was the “Security Decisions Via Untrusted Inputs”, one of our lesserused categories. This would be the catch-all for code-level implementation
problems in the mobile client. That’s distinct from the server-side coding
mistakes. This would capture things like buffer overflows, format string
vulnerabilities, and various other code-level mistakes where the solution is to
rewrite some code that’s running on the mobile device.

M8-Code Tampering
This category covers binary patching, local resource modification, method
hooking, method swizzling, and dynamic memory modification.
Once the application is delivered to the mobile device, the code and data
resources are resident there. An attacker can either directly modify the code,
change the contents of memory dynamically, change or replace the system
APIs that the application uses, or modify the application’s data and resources.
This can provide the attacker a direct method of subverting the intended use
of the software for personal or monetary gain.

M9-Reverse Engineering
This category includes analysis of the final core binary to determine its source
code, libraries, algorithms, and other assets. Software such as IDA Pro,
Hopper, otool, and other binary inspection tools give the attacker insight into
the inner workings of the application. This may be used to exploit other
nascent vulnerabilities in the application, as well as revealing information
about back-end servers, cryptographic constants and ciphers, and intellectual

M10-Extraneous Functionality
Often, developers include hidden backdoor functionality or other internal
development security controls that are not intended to be released into a
production environment. For example, a developer may accidentally include

a password as a comment in a hybrid app. Another example includes disabling
of 2-factor authentication during testing.

App Stores & Security Issues
An authenticated developer of a company creates mobile applications for
mobile users. In order to allow the mobile users to conveniently browse and
install these mobile apps, platform vendors like Google and Apple have
created centralized market places, for example, PlayStore (Google) and
AppStore (Apple). Yet there are security concerns.
Usually mobile applications developed by developers are submitted to these
market places without screening or vetting, making them available to
thousands of mobile users. If you are downloading the application from an
official app store, then you can trust the application as the hosting store has
vetted it. However, if you are downloading the application from a third-party
app store, then there is a possibility of downloading malware along with the
application because third-party app stores do not vet the apps.
The attacker downloads a legitimate game and repackages it with malware
and uploads the mobile apps to a third-party application store from where
the end users download this malicious gaming application, believing it to be
genuine. As a result, the malware gathers and sends user credentials such as
call logs/photo/videos/sensitive docs to the attacker without the user’s
Using the information gathered, the attacker can exploit the device and
launch any other attack. Attackers can also socially engineer users to
download and run apps outside the official apps stores. Malicious apps can
damage other applications and data, sending your sensitive data to attackers.

App Sandboxing Issues
Sandbox helps the mobile users by limiting the resources that an application
uses in the mobile device. However, many malicious applications can
overpass this allowing the malware to use all the device processing
capabilities and user data.

Secure Sandbox

It is an environment where each application runs its allocated resources and
data so the applications are secure and cannot access other application
resources and data.

Vulnerable Sandbox
It is an environment where a malicious application is installed and it exploits
the sandbox by allowing itself to access all data and resources.

Mobile Security – Mobile Spam
Take a look at the following screenshot. You might have received a similar
SMS which seemed to be genuine. In fact, after a bit of analysis, we realize
it is not genuine. It is an example of SMS phishing.

The links in the SMS may install malware on the user’s device or direct them
to a malicious website, or direct them to call a number set up to trick them
into divulging personal and financial information, such as passwords, account
IDs or credit card details. This technique is used a lot in cybercrimes, as it is
far easier to trick someone into clicking a malicious link in the e-mail than
trying to break through a mobile’s defenses. However, some phishing SMS
are poorly written and clearly appear to be fake.

Why SMS Phishing is Effective?
SMS Phishing is successful because it plays with the fear and anxiety of the
users. Irrational SMS instills fear in the mind of the users. Most of the
scenarios have to do with the fear of losing money, like someone has
purchased something using your credit cards.
Other instances include, the fear when an SMS accuses you of doing
something illegal that you haven’t done. Or an SMS regarding the possibility
of harming your family members. of your family, etc.

SMS Phishing Attack Examples
Now let us see a few examples to understand the cases where SMS Phishing
mostly happens.

Example 1
Generally, scammers use email to SMS to spoof their real identity. If you
google it, you may find many legitimate resources. You just google search:
email to SMS providers.

Example 2
The other classical scam is financial fraud which will ask you for PIN,
username, password, credit card details, etc.

Example 3
Spelling and bad grammar. Cyber criminals generally make grammar and
spelling mistakes because often they use a dictionary to translate in a specific
language. If you notice mistakes in an SMS, it might be a scam.

Example 4
SMS phishing attempt to create a false sense of urgency.

Example 5

Cybercriminals often use threats that your security has been compromised.
The above example proves it well. In the following case, the subject says you
have won a gift.

Example 6
In this case, an SMS asks you to reply so that they can verify that your
number is valid. This can increase the number of SMS spams in your number.

Example 7
Spoofing popular websites or companies. Scam artists use the name of big
organizations that appear to be connected to legitimate websites but actually
it takes you to phony scam sites or legitimate-looking pop-up windows.

Prevention and Solutions
In order to protect ourselves from SMS phishing some rules have to be kept
in mind.

Financial companies never ask for personal or financial information, like
username, password, PIN, or credit or debit card numbers via text message.

Smishing scams attempt to create a false sense of urgency by requesting an
immediate response. Keep calm and analyze the SMS.

Don’t open links in unsolicited text messages.

Don’t call a telephone number listed in an unsolicited text message. You should
contact any bank, government, agency, or company identified in the text
message using the information listed in your records or in official webpages.

Don’t respond to smishing messages, even to ask the sender to stop contacting

Use caution when providing your mobile number or other information in response
to pop-up advertisements and “free trial” offers.

Verify the identity of the sender and take the time to ask yourself why the sender
is asking for your information.

Be cautious of text messages from unknown senders, as well as unusual text
messages from senders you do know, and keep your security software and
applications up to date.

Pairing Mobile Devices on Open Bluetooth and
Wi-Fi Connections
Bluetooth is a similar radio-wave technology, but it is mainly designed to
communicate over short distances, less than about 10m or 30ft. Typically,
you might use it to download photos from a digital camera to a PC, to hook
up a wireless mouse to a laptop, to link a hands-free headset to your
cellphone so you can talk and drive safely at the same time, and so on.
To obtain this connection, devices exchange each other’s PIN, but in general
as a technology it is not secure. It is a good practice to repair the devices
after a period of time.

What a hacker can do with a paired device?

Play sounds of incoming call

Activate alarms

Make calls

Press keys

Read contacts

Read SMS

Turn off the phone or the network

Change the date and time

Change the network operator

Delete applications

Security measures for Bluetooth devices

Enable Bluetooth functionality only when necessary.

Enable Bluetooth discovery only when necessary.

Keep paired devices close together and monitor what’s happening on the

Pair devices using a secure passkey.

Never enter passkeys or PINs when unexpectedly prompted to do so.

Regularly update and patch Bluetooth-enabled devices.

Remove paired devices immediately after use.

Mobile Security – Android OS
As many of us know, software is developed by Google for mobile devices with
processing capabilities for smartphones and tablets. Its kernel is based on
Linux. Its installed applications run in a sandbox. However, many producers
have released its antiviruses for such OS, like Kasperky, MCAfee, and AVG
Technologies. Even though antivirus application runs under sandbox, it has a
limit to scan the environment.
Some feature of android OS are as follows −

Dalvik virtual machine optimized for mobile device

SQLite database for structured data

Integrated browser based on WebKit engine

Support of different media formats like audio, images, video

Rich development environment like emulators (Bluestack), debugging tools

Android OS Architecture
The following image shows the overall architecture of Android OS −

The first layer is Application, includes applications such as SMS, calendars, and
other third party applications.

The second layer is Application Framework, which includes −
o View system, which is for developers to create boxes, lines, grids, etc.
o Content providers permit applications to access and use data from third

party applications.
o Activity manager controls the life cycle of an application.
o Resource manager allocates resources to an application.
o Notification manager helps to shows notifications of applications.

The third layer is libraries, which is the most important part. It utilizes the
function of the application, for example, to store date in a database. It is SQLite
that utilizes this function.

The fourth layer is the Linux Kernel. It holds all the drivers of the hardware
components, such as camera, wireless, storage, etc.

Android Device Administration API

The Device Administration API introduced in Android 2.2 provides device
administration features at the system level. These APIs allow developers to
create security-aware applications that are useful in enterprise settings, in
which IT professionals require rich control over employee devices.
The device admin applications are written using the Device Administration
API. These device admin applications enforce the desired policies when the
user installs these applications on his or her device. The built-in applications
can leverage the new APIs to improve the exchange support.
Here are some examples of the types of applications that might use the
Device Administration API −

Email clients

Security applications that do remote wipe

Device management services and application

The examples used in this tutorial are based on the Device Administration
API sample, which is included in the SDK samples (available through the
Android SDK Manager) and located on your system as

Sample Application
This sample application offers a demo of device admin features. It presents
the users with a user interface that lets them enable the device admin

Once the users have enabled the application, they can use the buttons in the
user interface to do the following −

Set password quality.

Specify requirements for the user’s password, such as minimum length, the
minimum number of numeric characters it must contain, and so on.

Set the password. If the password does not conform to the specified policies, the
system returns an error.

Set how many failed password attempts can occur before the device is wiped (that
is, restored to factory settings).

Set how long from now the password will expire.

Set the password history length (length refers to the number of old passwords
stored in the history). This prevents the users from reusing one of the last
passwords they previously used.

Specify that the storage area should be encrypted, if the device supports it.

Set the maximum amount of inactive time that can elapse before the device locks.

Make the device lock immediately.

Wipe device data (that is, restore factory settings).

Disable the camera.

Mobile Security – Android Rooting
Rooting is a word that comes from Linux syntax. It means the process which
gives the users super privilege over the mobile phone. After passing and
completing this process, the users can have control over SETTINGS,
FEATURES, and PERFORMANCE of their phone and can even install software
that is not supported by the device. In simple words, it means the users can
easily alter or modify the software code on the device.
Rooting enables all the user-installed applications to run privileged
commands such as −

Modifying or deleting system files, module, firmware and kernels

Removing carrier or manufacturer pre-installed applications

Low-level access to the hardware that are typically unavailable to the devices in
their default configuration

The advantages of rooting are −

Improved performance

Wi-Fi and Bluetooth tethering

Install applications on SD card

Better user interface and keyboard

Rooting also comes with many security and other risks to your device such
as −

Bricking the device

Malware infection

Voids your phone’s warranty

Poor performance

Android Rooting Tools

As Android OS is an open source, the rooting tools that can be found over the
internet are many. However, we will be listing just some of them −

Universal Androot
You can download from

Mac − Open a terminal window to the directory containing the files, and type
chmod +x.” followed by ./

Linux − Open a terminal window to the directory containing the files, and type
chmod +x.” followed by ./

Step 7 − Your Android device has been rooted.

Android Trojan
ZitMo (ZeuS-in-the-Mobile)

Zitmo refers to a version of the Zeus malware that specifically targets mobile
devices. It is a malware Trojan horse designed mainly to steal online banking
details from users. It circumvents mobile banking app security by simply
forwarding the infected mobile’s SMS messages to a command and control
mobile owned by cybercriminals. The new versions of Android and BlackBerry
have now added botnet-like features, such as enabling cybercriminals to
control the Trojan via SMS commands.

FakeToken and TRAMP.A
FakeToken steals both authentication factors (Internet password and mTAN)
directly from the mobile device.
Distribution Techniques − Through phishing emails pretending to be sent
by the targeted bank. Injecting web pages from infected computers,
simulating a fake security app that presumably avoids the interception of SMS
messages by generating a unique digital certificate based on the phone
number of the device. Injecting a phishing web page that redirects users to
a website pretending to be a security vendor that offers the “eBanking SMS

Guard” as protection against “SMS message interception and mobile Phone
SIM card cloning”.

Fakedefender and Obad
Backdoor.AndroidOS.Obad.a is an Android Trojan known for its ability to
perform several different functions such as, but not limited to, remotely
performing commands in the console, sending SMS messages to premiumrate numbers, downloading other malware and even installing malware on an
infected device just to send it to someone else through Bluetooth
communication. The Backdoor.AndroidOS.Obad.a Android Trojan is a
treacherous threat that disturbingly runs in the background lacking a
common interface or front-end access.

FakeInst and OpFake
Android/Fakeinst.HB is a repackaged clone of a popular, free racing game.
Unlike the original, the repackaged clone requires the user to pay a charge,
supposedly to “access higher game levels”.

AndroRAT and Dendoroid
It is a free Android remote administration tool (RAT) known as AndroRAT
(Android.Dandro) and what was believed to be the first ever malware APK
binder. Since then, we have seen imitations and evolutions of such threats in
the threat landscape. One such threat that is making waves in underground
forums is called Dendroid (Android.Dendoroid), which is also a word meaning
– something is tree-like or has a branching structure.

Mobile Security – Securing Android
Nowadays, mobile phone devices are substituting computers in some special
cases and from this comes the concern of the users and system
administrators to restrict rights to the application or the user. Hence, we
protect computers from being infected by installing antiviruses in order to
prevent any possible unpleasant situation, where some data is lost or goes
Following are a few recommendations to protect our mobile devices −

Enable lock screen so as not to be directly accessible by third parties.

Keep the operating system updated and patch the apps all the time.

Download apps that are officially marked by Google or from genuine sites that
offers this app.

Don’t root android devices.

Install and update antivirus app on android device.

Don’t download android package files directly.

Use android protectors that allows you to set password to email, SMS, etc.

Google Apps Device Policy
Google Apps Device app allows a Google Apps domain admin to set security
policies for android devices. This app is available only for business,

government, and education accounts, which allows IT administrators
remotely to push policies and enforce them. Additionally, it helps them locate
mobile devices and lock them.

Remote Wipe Service
Remote Wipe Service is a service that allows administrators to reset or erase
the information in the lost or stolen device. To avail this service, the device
should install Google Sync or Device Policy. This can also delete all the
information in the device such as mail, calendar, contacts, etc. but cannot
delete the data stored on the device’s SD card. When this service completes
its task, it prompts the user with a message as an acknowledgement to the
delete function.
Follow these steps to enable this setting for users −

Step 1 − Sign in to the Google Admin console
Step 2 − Click Device management → Mobile → Device management settings
Step 3 − Check the Allow user to remote wipe device box.
Step 4 − Click Save Changes.
You can apply this setting to your whole organization or by organizational
unit to enable remote wipe for only a specific group of users.
Once enabled, a user can remotely wipe their device by following these steps

Step 1 − Go to their My Devices page. The user will need to enter their
password to access this page, even if they’re already signed in to their
Step 2 − Click Wipe Device.
A window appears with this warning text: This will wipe all application and
personal data from your device. Anything that hasn’t been synced will be lost.
Are you sure you want to proceed?
Step 3 − Click Confirm to wipe the device.
Following is the Administrator Console −

Mobile Security – Android Security Tools
In this chapter, we will discuss android security tools mainly those that are
meant for protection from malware installation and downloads.

DroidSheep Guard
DroidSheep Guard monitors your phone’s ARP-Table and it warns you through
pop-up alerts, in case it detects malicious entries. It can instantly disable a
Wi-Fi connection to protect your accounts. This can guard against all ARPbased attacks, such as DroidSheep and Faceniff, man-in-middle attacks,
handmade attacks, etc. You can use Facebook, eBay, Twitter, and Linkedln
accounts on public Wi-Fi securely. To download DroidSheep Guard, go

TrustGo Mobile Security and Sophos Mobile
This is one of the best free security antivirus and it can be downloaded
through Google Play. TrustGo provides the usual slate of anti-theft tools along
with malware protection and an interesting app certification system, giving
you information about apps before you download them. Its official webpage

Using up-to-the-minute intelligence from SophosLabs, it automatically scans
apps as you install them. This anti-virus functionality helps you avoid
undesirable software, which can lead to data loss and unexpected costs. It
also protects your device from attacks via USSD or other special codes.
If your device is lost or stolen, a remote lock or wipe will shield your personal
information. This can be downloaded from the following Google Play link −

Shields your devices (smartphones, tablets, phablets) from malware.

Locates your lost or stolen phone.

Protects your private data (photos, SMS, etc.) from theft.

Monitors how each app collects sensitive data.

Blocks unauthorized access to other applications installed on your device.

Lights on system resources, to help save battery power.

Android Vulnerability Scanner: X-Ray
X-Ray scans your Android device to determine if there are vulnerabilities that
remain unpatched by your carrier. It presents you with a list of vulnerabilities
that it is able to identify and allows you to check for the occurrence of
vulnerabilities on your device. This is automatically updated with the ability
to scan for new vulnerabilities as they are discovered and disclosed.
X-Ray has detailed information about a class of vulnerabilities known
as privilege escalation vulnerabilities. Such vulnerabilities can be
exploited by a malicious application to gain root privileges on a device and
perform actions that would normally be restricted by the Android operating

system. X-Ray is installed directly (via an APK) and not through the Google
Play store.

Android Device Tracking Tools
Android tracking tools are tools that help us find our lost mobile devices.
Some of them are −

Find My Phone
Send a text message to your phone and it will text back its current location,
or have it ring loudly if its somewhere nearby. Secure your emails, text
messages, photos, notes, calendar and more by remotely wiping your phone
with SMS. Keep tabs on your phone’s SIM card. It can be downloaded from
the following link −

Prey Anti-theft
Prey lets you keep track of your laptop, phone, or tablet if it is stolen or
missing. It supports geolocation. It’s lightweight, open source software gives
is and

Mobile Security – Apple iOS
iOS is Apple mobile’s operating system established for its iPhones. It
maintains and sustains other Apple devices such as iPod Touch, iPad, and
Apple TV. Using the Mac OS X, the iOS operating system is fabricated.
The user interface is based on the concept of direct manipulation, using multitouch gestures. This has many other options and features using which daily
work becomes easy and this can be updated on your iPhone, iPad, or iPod
Touch using Wi-Fi and other wireless networks.

Jailbreaking iOS
Jailbreaking is taking control of the iOS operating system that is used on
Apple devices, in simple words the symmetry of Rooting in Android devices.
It removes the device from the dependencies on exclusive Apple source
applications and allows the user to use third-party apps unavailable at the
official app store.
It is accomplished by installing a modified set of kernel patches that allows
you to run third-party applications not signed by the OS vendor. It is used to
add more functionality to standard Apple gadgets. It can also provide root
access to the operating system and permits download of third-party
applications, themes, extensions, etc. This removes sandbox restrictions,
which enables malicious apps to access restricted mobile resources and
Jailbreaking, like rooting, also has some security risks to your device −

Voids your phone’s warranty

Poor performance

Bricking the device

Malware infection

Types of Jailbreaking
When the device starts booting, it loads Apple’s own iOS, and to install apps
from third parties, the device must then be broken and have the kernel
patched each time it is turned on. There are three types of jailbreaking
methods used.

iBoot Exploit
An iBoot jailbreak allows the file system and iboot level access. This type of
exploit can be semi-tethered if the device has a new boot-rom. This is mostly
used to reduce low-level iOS controls. This exploit method takes the help of
the hole in the iBoot to delink the code signing appliance and then the
customer can download the required applications. Using this method, the
users configure the mobile to accept custom firmware and probably jailbreak

Userland Exploit
A userland jailbreak allows user-level access but doesn’t allow iboot-level
access. This type of exploit cannot be tethered as it cannot have recovery
mode loops. These can be patched by Apple. The userland exploits use a
loophole in the system application to gain control of that application. The
exploit can only give control to the filesystem. This type of exploit can access
non-vital code in the application and is user friendly and platform

Bootrom Exploit
A bootrom jailbreak can break all the low-level authentications such as
providing filesystem, iBoot, and NOR access (custom boot logos). This
process finds a hole in the application to discard the signature checks. It can’t
be corrected by Apple. A bootrom jailbreak allows user-level access and
iBoot-level access. These cannot be patched by Apple.

Jailbreaking Techniques
There are two types of Jailbreaking techniques.

Untethered Jailbreaking
Untethered jailbreak is a technique of rebooting the mobile device without
connecting it to the system every time it is booted. If the battery of the device
is spoiled, after changing it boots as usual. Tools for this are PwnageTool,
Greenpois0n, Sn0wbreeze, and Limera1n.

Tethered Jailbreaking
If the device starts backing up on its own, it will no longer have a patched
kernel, and it may get stuck in a partially started state. In order for it to start
completely and with a patched kernel, it essentially must be “re-jailbroken”
with a computer (using the “boot tethered” feature of a jailbreaking tool)
each time it is turned on.

App Platform for Jailbroken Devices: Cydia
from It helps iOS users to install other third party
applications. Cydia has different extensions, themes, features, and
It is a graphical front-end to Advanced Packaging Tool (APT) with the dpkg
package management system, which means that the packages available in
Cydia are provided by a decentralized system of repositories (also called
sources) that list these packages.

Guidelines for Securing Windows OS Devices
Following are some of the practical guidelines to secure mobile phones. The
list is based on the best practices. Neither are they always mandatory nor are
these universal rules.

Lock the screen

Download apps only from trusted sources.

Keep your phone updated with WP8 security updates

Use Zune desktop software to back up your device data

Try to connect to secured Wi-Fi networks

Set up passwords for WP8 lock screen

Protect your WP8 SIM (Subscriber Identity Module) with a PIN.

Mobile Security – BlackBerry OS
BlackBerry OS is a proprietary mobile operating system developed by
Research in Motion for its BlackBerry line of smartphones and handheld
devices. It includes a Java based thirdparty application framework that
implements J2ME Mobile Information Device Profile v2 (MIDP2) and
Connected Limited Device Configuration (CLDC), as well as a number of RIM
specific APIs.
Some of the features of BlackBerry include −

Native support for corporate email

BlackBerry enterprise server

BlackBerry messenger

BlackBerry internet service

BlackBerry email client

BlackBerry Enterprise Solution Architecture
Blackberry Enterprise Solution allows the mobile users to wirelessly access
their organization emails and other business-critical applications, safely and
securely. BlackBerry Enterprise Solution Architecture is comprised of six vital
elements. They are −

BlackBerry Enterprise Server

Blackberry Mobile Data System

BlackBerry Smartphones

BlackBerry Connect Software

Blackberry Alliance Program

BlackBerry Solution Services

The enterprise server, together with enterprise messaging and collaboration
systems, provides email access to the mobile users, enterprise instant
messaging, and personal information management tools. Poorly configured
firewalls increase the risk of attacks. The Web, Database, and Application
Server contain vulnerabilities. If the attacker detects those vulnerabilities,

then he or she can easily carry out an attack and take control over the entire

BlackBerry Attack Vectors
BlackBerry faces many attacks since there are many new tools and methods
available for finding potential vulnerabilities present on BlackBerry devices.
Attack vectors attract users to download malicious software on their mobiles.
Finding website vulnerabilities using tools, etc. are the few techniques used
by an attacker for carrying out attacks on BlackBerry devices. Apart from
these techniques, there are many more attack vectors that allow attackers to
launch attacks on BlackBerrys that include −

Malicious Code Signing

Memory and Processes Manipulations

Email Exploits

TCP/IP Connections Vulnerabilities

Blackberry Malwares

JAD File Exploits

Short Message Service (SMS) Exploits

PIM Data Attacks

Telephony Attacks

Malicious Code Signing
A BlackBerry application must be signed by RIM to get full access to the
operating system APIs. If a required signature is missing or the application is
altered after signing, the JVM will either refuse/restrict the API access to the
application or will fail at run-time with an error message. Attackers can obtain
code-signing keys anonymously using prepaid credit cards and false details,
sign a malicious application, and publish it on the BlackBerry app world.
Attackers can also compromise a developer’s system to steal code-signing
keys and passwords to decrypt the encrypted keys.

JAD File Exploits and Memory/ Processes Manipulations
JAD files include the attributes of a Java application, such as app description
and vendor details and size, and provides the URL where the application can
be downloaded. It is used as a standard way to provide Over The Air (OTA)
installation of Java applications on J2ME mobile devices. Attackers can use
specially crafted .jadfiles with spoofed information and trick users into
installing malicious apps.

Short Message Service (SMS) Exploits
Regular PC users are more likely to be targeted by premium
rate dialers applications that connect a user’s modem to a premium rate
telephone number, which results in more service provider bills than expected.
The same mechanism is enforced in BlackBerry but doesn’t use premium rate

Email Exploits
In BlackBerry mobile, all emails are sent, received, and read through
the net.rim.blackberry.api.mail package and this package can be used
only on signed applications. BlackBerry attachment service supports only files
with extensions such as .doc, .pdf, .txt, .wpd,.xls, and .ppt, but it can send
any kind of file via email. An attachment with file type .cod is not supported
by BlackBerry.

PIM Data Attacks

Personal Information Management (PIM) data in the PIM database of a
BlackBerry device includes address books, calendars, tasks, and memo pads
information. Attackers can create malicious signed applications that read all
the PIM data and send it to an attacker using different transport mechanisms.
The malicious applications can also delete or modify the PIM data.

TCP/IP Connections Vulnerabilities
If the device firewall is off, signed apps can open TCP connections without
the user being prompted. Malicious apps installed on the device can create a
reverse connection with the attacker enabling him or her to utilize infected
device as a TCP proxy and gaining access to organization’s internal resources.
Attackers can also exploit the reverse TCP connection for backdoors and
perform various malicious information gathering attacks.

Mobile Security – BlackBerry Devices
Following are some of the practical guidelines to secure BlackBerry devices.
The list is based on the best practices and these are not universal rules.

Mobile Security – MDM Solution
Mobile Device Management (MDM) software is a vital component that
monitors, safeguards, manages, and supports different types of mobile
devices and tablets including iPhone, iPad, Android, and BlackBerry, along
with the applications that run on them. It monitors all mobile devices with
different operating system such as Android, Windows, and Symbian mobile.
MDM provides platforms for over-the-air or wired distribution of applications,
data, and configuration settings for all types of mobile devices along with
mobile phones, smartphones, tablet computers, etc.
With the help of MDM, enterprise-wide policies can be implemented easily to
reduce support costs, time, and business and security threats. All the
company-owned, consumer owned, as well as the employee-owned devices
across the enterprise can be easily managed with the help of it.
MDM can reduce support cost and minimize business threats just by
safeguarding and controlling all the data and configuration settings of all the
mobile devices in the network.

devices such as smartphones and tablets including iPhones, iPads, Androids,
Windows Phones, BlackBerrys, and Kindle Fires. Using the integrated cloud
platform, the MaaS360 streamlines MDM with improved visibility and control
that spans across mobile devices, applications, and documents.

Bring Your Own Device (BYOD)
BYOD — also called Bring Your Own Technology (BYOT), Bring Your Own
Phone (BYOP), and Bring Your Own Personal Computer (BYOPC) — refers to
the policy of permitting employees to bring personally owned mobile devices

(laptops, tablets, and smart phones) to their workplace, and to use those
devices to access privileged company information and applications.
There are four basic options, which allow −

Unlimited access for personal devices.

Access only to non-sensitive systems and data.

Access, but with IT control over personal devices, apps, and stored data.

Access, while preventing local storage of data on personal devices.

BYOD Risks
Implementing BYOD in the company has its own risks and are as follows −

Increases the possibility of data leak in the company.

Increases the possibility of exploits in the company as there are more mobile
devices in the network.

Chances of mixing personal data with job data.

Increase in possibility to access unauthorized data.

BYOD Policy Implementation
Following are the security guidelines for both administrators and employees.

BYOD Security Guidelines for Administrator
The administrator should follow the guidelines listed here to implement
mobile device security −

Publish an enterprise policy that specifies the acceptable usage of consumer grade
devices and bring-your-own devices in the enterprise.

Publish an enterprise policy for cloud.

Enable security measures such as antivirus to protect the data in the datacenter.

Implement policy that specifies which levels of application and data access are
allowed on consumer-grade devices, and which are prohibited.

Specify a session timeout through Access Gateway.

Specify whether the domain password can be cached on the device, or whether
users must enter it every time they request access.

Determine the allowed Access Gateway authentication methods from the following

o No authentication
o Domain only
o RSA SecurlD only
o Domain + RSA SecurlD
o SMS authentication

BYOD Security Guidelines for Employees











Apply software updates when new releases are available.

Logging and limited data on device.

Device encryption and application patching.

Managed operating environment.

Managed application environment.

Press the power button to lock the device whenever it is not in use.

Verify the location of printers before printing sensitive documents.

Utilize a passcode lock to protect the access to the mobile device; consider the
eight-character non-simple passcode.

Report a lost or stolen device to IT so they can disable certificates and other
access methods associated with the device.

SMS Phishing Countermeasures
This chapter explains certain guidelines and tools related to mobile security.
In order to protect ourselves from SMS phishing, some rules have to be kept
in mind.

Financial companies never ask for personal or financial information, like
usernames, passwords, PINs, or credit or debit card numbers via text message.

Smishing scams attempt to create a false sense of urgency by requesting an
immediate response required. Keep calm and analyze the SMS.

Don’t open links in unsolicited text messages.

Don’t call a telephone number listed in an unsolicited text message. You should
contact any bank, government, agency, or company identified in the text
message using the information listed in your records or in official webpages.

Don’t respond to smishing messages, even to ask the sender to stop contacting

Use caution when providing your cell phone number or other information in
response to pop-up advertisements and “free trial” offers.

Verify the identity of the sender and take time to ask yourself why the sender is
asking for your information.

Be cautious of text messages from unknown senders, as well as unusual text
messages from senders you do know, and keep your security software and
applications up to date.

Mobile Security – Pen Testing
In this chapter, we will discuss the basic concepts of penetration testing of
mobile phones. As you will see, it differs based on the OS.

Android Phone Pen Testing
The basic steps in Android OS phone are as follows −
Step 1 − Root the OS with the help of tools such as SuperOneClick,
Superboot, Universal Androot, and Unrevoked in order to gain administrative
access to OS and Apps.
Step 2 − Perform DoS attack in order to make a stress test of Apps or OS
AnDOSid. It can

Step 3 − Check for vulnerabilities in web browsers. Mainly check whether
cross-application scripting error is present in the Android browser.

Step 4 − Check SQLite for vulnerabilities mainly its purpose is to check for
any sensitive information, if it is in an encrypted form (like password,
contacts, database links, etc.). One of the best tools used for this is sqlmap
which is found in Kali distribution.

Step 5 − Try to edit, steal, replace users’ information. It can be

Step 6 − Detect capability leaks in Android devices by using the tool

iPhone Pen Testing
Step 1 − Try to Jailbreak the iPhone using tools such as Redsn0w, Absinthe,
Sn0wbreeze, and PwnageTool.
Step 2 − Try to unlock the iPhone. To unlock the iPhone use tools such as
from http://www.iphonesimfree.comand anySIM.

Step 3 − Use SmartCover to bypass passcode for which you need to follow
these steps: Hold the power button of an iOS operating device until the power
off message appears. Close the smart cover until the screen shuts and opens
the smart cover after few seconds. Press the cancel button to bypass the
password code security.
Step 4 − Hack iPhone using Metasploit, which is incorporated in Kali
distribution. Use the Metasploit tool to exploit the vulnerabilities in the
iPhone, based on the vulnerabilities that you find.
As Metasploit is a Rapit7 company product further details can be found

Step 5 − Check for the access point with the same name and encryption
Step 6 − Do a man-in-the-middle/SSL stripping attack by intercepting
wireless parameters of iOS device on a Wi-Fi network. Send malicious packets
on the Wi-Fi network using the Cain & Abel tool or even Wireshark.
Step 7 − Check whether the malformed data can be sent to the device. Use
social engineering techniques such as sending emails or SMS to trick the user
into opening links that contain malicious web pages.

Windows Phone Pen Testing
Following are the steps for Windows phone pen testing.
Step 1 − Try to turn off the phone by sending an SMS. Send a SMS to the
phone, which turns off the mobile and reboots it again.
Step 2 − Try to jailbreak the Windows phone. Use the WindowBreak program
to jailbreak/unlock the Windows phone. You can get more details about this

Step 3 − Check for on-device encryption. Check whether the data on the
phone can be accessed without a password or PIN.
Step 4 − Check for a vulnerability in Windows Phone Internet Explorer.
Check whether the flaw in CSS function in Internet Explorer allows the
attackers to gain full access over the phone through remote code execution.

BlackBerry Pen Testing
Step 1 − Firstly, you do a blackjacking on the BlackBerry. Use BBProxy tool
to hijack the BlackBerry connection which can be found on the internet.
Step 2 − Check for flaws in the application code signing process. Obtain
code-signing keys using prepaid credit cards and false details, sign a
malicious application, and publish it on the BlackBerry app world.
Step 3 − Perform an email exploit. Send an email or message to trick a user
to download a malicious .cod application file on the BlackBerry device.
Step 4 − Perform a DoS attack. Try sending malformed Server Routing
Protocol (SRP) packets from the BlackBerry network to the router to cause a
DoS attack. Some tools were mentioned in the previous chapters.

Step 5 − Check for vulnerabilities in the BlackBerry Browser. Send
maliciously crafted web links and trick the users to open links containing
malicious web pages on the BlackBerry device.
Step 6 − Search for password protected files. Use tools like Elcomsoft Phone
Password Breaker that can recover password protected files and backups
from BlackBerry devices.
