In yet another blow to the tenuous false sense of security among Apple users, the Russian antivirus firm Dr. Web has uncovered what it claims is a first-of-its-kind fake installer Trojan targeting Mac machines and extorting their users with SMS fraud.

FTC Launches Investigations into Mobile Apps for Kids

The Federal Trade Commission on Monday said it’s launching “non-public investigations” to determine if mobile application providers are violating federal laws by collecting information on children without their parents’ permission.A report indicates almost 60 percent (235) of the children-centric mobile apps the agency reviewed from Google and Apple app stores collected device IDs and other private data often shared with an advertising network, analytics company or other third party. More than half also displayed advertising, such as one children’s app that showed an advertisement for an adult singles club. Only 20 percent disclosed their privacy policy.


Google’s brand new application verification service for Android, released in JellyBean 4.2, fails to measure up to its commercial counterparts, according to researchers from North Carolina State University.The new service determines whether applications installed on Android devices are malicious, yet in comparisons with 10 leading antivirus engines, and even Google’s newly acquired VirusTotal scanner, the new service detects at best 20 percent of Android malware.

Fake and malicious Android apps have become an industry unto themselves in the last couple of years, as attackers have sought to capitalize on the massive market share that the mobile OS enjoys worldwide. It’s a safe bet that any popular new app will attract a malicious copycat version, and researchers have found that the latest app on this list is Angry Birds Star Wars. 

Google has divulged more information about its forthcoming application verifier for the Android operating system. The feature is being rolled out over the air alongside the latest build of the OS, Jelly Bean 4.2, on Nexus 7 and Galaxy Nexus devices as of yesterday.While it can be disabled, the app verifier feature is turned on by default according to a new description from Google/Nexus that describes the process as follows:
