Abstract
Mobile devices are becoming a method to provide an efficient
and convenient way to access, find and share information;
however, the availability of this information has caused an
increase in cyber attacks. Currently, cyber threats range from
Trojans and viruses to botnets and toolkits. Presently, 96% of
mobile devices do not have preinstalled security software while
approximately 65% of the vulnerabilities are found within the
application layer. This lack in security and policy driven
systems is an opportunityfor malicious cyber attackers to hack
into the various popular devices. Traditional security software
found in desktop computing platforms, such as firewalls,
antivirus, and encryption, is widely used by the general public
in mobile devices. Moreover, mobile devices are even more
vulnerable than personal desktop computers because more
people are using mobile devices to do personal tasks. This
review attempts to display the importance of developing a
national security policy created for mobile devices in order to
protect sensitive and confidential data. Results of this review
provide methods to address security related issues in mobile
devices.
Introduction
Currently, mobile devices are the preferred device for web browsing, emailing,
using social media and making purchases. Due to their size, mobile devices are
easily carried in people’s pockets, purses or briefcases. Unfortunately, the popularity
of mobile devices is a breeding ground for cyber attackers. Operating systems
on mobile devices do not contain security software to protect data. For example,
traditional security software found in personal computers (PCs), such as firewalls,
antivirus, and encryption, is not currently available in mobile devices (Ruggiero, 2011).
In addition to this, mobile phone operating systems are not frequently updated like their
PC counterparts. Cyber attackers can use this gap in security to their advantage. An
example of this gap in security is seen in the 2011 Valentine’s Day attack. Cyber-
attackers dispersed a mobile picture-sharing application that covertly sent premium-
rate text messages from a user’s mobile phone (Ruggiero, 2011). Thus, this example
illustrates the importance of having a security policy for mobile phones.
Social Networking and Electronic Commerce (E-
Commerce) Applications
Many people rely on their mobile devices to do numerous activities, like sending
emails, storing contact information, passwords and other sensitive data. In
addition to this, mobile devices are the device of choice when it comes to social
networking; thus, mobile applications for social networking sites (Facebook, Twitter,
Google+) are another loophole for cyber attackers to gain personal data from
unsuspecting users (Ruggiero, 2011). Social networking sites are host to a surplus of
personal data. That is why malicious applications that use social networking sites to
steal data yield severe consequences. Recently, M-Commerce or “mobile e-
commerce” has gained popularity in our society. Many smartphone users can now
conduct monetary transactions, such as buying goods and applications (apps),
redeeming coupons and tickets, banking and processing point-of-sale payments
(Ruggiero, 2011). Again, all of these smartphone functions are convenient for the user
but advantageous for malicious cyber attackers. Ultimately, there is a niche in
technology for cyber security software that is specifically designed for the mobile
operating system.
Hypothetical Consequences of Cyber Attacks on
Smartphones
The consequences of a cyber attack on a smartphone can be just as
detrimental, or even more detrimental than an attack on a PC. According
to Patrick Traynor, a researcher and assistant professor at the Georgia Tech
School of Computer Science, mobile apps rely on the browser to operate
(Traynor, Ahamad, Alperovitch, Conti, & Davis, 2012). As a result of this,
more Web-based attacks on mobile devices will increase throughout the
year. Traynor also states that IT professionals, computer scientists and
engineers still need to explore the variations between mobile and traditional
desktop browsers to fully understand how to prevent cyber attacks (Traynor,
Ahamad, Alperovitch, Conti, & Davis, 2012).
Challenges with a Mobile Browser
One cyber security challenge for mobile devices is the screen size. For
example, web address bars (which appear once the user clicks on the
browser app) disappear after a few seconds on a smartphone because of the
small screen size (Traynor, Ahamad, Alperovitch, Conti, & Davis, 2012). This
is usually the first-line of defense for cyber security. Checking the Uniform
Resource Locator (URL) of a website is the first way users can insure that
they are at a legitimate website. Moreover, SSL certificates for a website
are usually more difficult to find on a mobile phone browser (Traynor,
Ahamad, Alperovitch, Conti, & Davis, 2012). This adds another gap in
security for mobile devices. Furthermore, the touch-screen attribute of mobile
phones can be cause for concern when dealing with cyber attackers. Traynor
states that the way elements are placed on a page and users’ actions are all
opportunities to implant an attack. An illustration of this is seen when an
attacker creates an attractive display content (i.e. an advertisement for an
app or a link to a social media app) in which the malicious link is carefully
hidden underneath a legitimate image. Unfortunately, once the user clicks
the image they can be redirected to the malicious content via the link
(Traynor, Ahamad, Alperovitch, Conti, & Davis, 2012).

Legitimate Applications that Can Be Used to
Retrieve Information
Presently, there is valid spy software available for
various mobile devices. An example of this is
FlexiSpy, a legitimate commercial spyware program that
cost over $300 (United States Computer Emergency
Readiness Team, 2010). FlexiSpy can:
• Listen to actual phone calls as they happen;
• Secretly read Short Message Service (SMS) texts,
call logs, and emails;
• Listen to the phone surroundings (use as
remote bugging device);
• View phone GPS location;
• Forward all email events to another inbox;
• Remotely control all phone functions via SMS;
• Accept or reject communication based on
predetermined lists; and
• Evade detection during operation (United States
Computer Emergency Readiness Team, 2010).
