In McAfees target="_blank">Mobile Security: McAfee Consumer Trends Report June 2013, which reveals new ways that cybercriminals abuse app permissions to commit fraud and install malware. The report also shows that games are the most common form of malware-infected app.
McAfee Labs found that under the camouflage of free apps, criminals are able to get consumers to agree to invasive permissions that allow scammers to deploy malware. The permissions in free apps, funded by adware, leak personal information which ad networks use to serve targeted ads; however, McAfee found that 26 per cent of apps are likely more than just adware. SMS scams and rooting exploits were among the most popular types of threats seen across a variety of apps.
Most consumers dont understand or even worry about the app permissions they agree to, said Luis Blando, VP of mobile product development at McAfee. Because of that, cybercriminals are increasingly abusing app permissions as an efficient way to deliver mobile malware. Through these agreements mobile consumers are willingly putting their personal information into the hands of criminals disguised as ad networks, and opening up endless doors for scammers.
The suite of capabilities in McAfee Mobile Innovations app today addresses a variety of threats to users on mobile devices. Features include:
Premium Rate SMS Scams: A Pricey Problem
The report examines Fake Installer, a piece of SMS malware disguised within a free app that sends up to seven messages. At a typical premium rate of $4 USD per message, that free app can cost up to $28 USD as the malware tells a consumers device to send messages to or receive messages from a premium rate SMS number.
Bogus App Ratings: Read between the Stars
The report analyzes FakeRun, malware that tricks users in the United States, India, and 64 other countries into giving an app a five-star rating on Google Play. Once an app developer has been rated highly, other apps they publish will be trusted, which creates more opportunities for a criminal to publish and distribute malware-carrying apps.
Malicious Apps by Category: Games Top the List
The report also identifies the most popular apps that carry malware. Of the top 20 downloads of malware-infected apps, games won the popularity contest, followed by personalization and a tie between tools, music, lifestyle (a cover category for adult content) and TV.
