TrustGo Security Labs: Advanced Malware Found on Google Play

New Threat Disguises Itself As Popular Mobile Security App

Santa Clara, Calif., October 17, 2012 – TrustGo Mobile Inc. (TrustGo), a leading mobile security company, today announced TrustGo Security Labs discovered a new and dangerous virus on the world’s leading Android app marketplace, Google Play. The malicious code was hidden within an app named, “Updates” by developer Good Byte Labs (Package name: com.updateszxt) and was designed to look like an update to the Lookout™ mobile security application.

Dubbed Trojan!FakeLookout.A by TrustGo Security Labs, the malicious app steals user SMS/MMS messages and video files, as well as all the files on the user’s SD card and transmits them to a remote FTP server operated by the malware maker. With these functions, the virus has the potential to cause significant privacy breaches and to expose all the sensitive personal and business data on users’ devices to malicious actors.

The new malware is significant in that it hides its presence on the infected user’s device by removing itself from the device’s full Application List, leaving only a false and misleading icon in the Downloaded Apps list that uses the familiar logo of Lookout, and the name, “Updates.” The offending app was first seen on October 15, 2012 and positively identified as malicious just 36 hours later. TrustGo immediately notified Google of this new virus and confirms that the infected app has been removed from Google Play, limiting the infection to a small number of users. TrustGo has also alerted other app marketplaces that have been found to contain the threat.

FakeLookout.A indicates a new approach being attempted by malware makers. The virus-containing app sent its stolen data to a domain hosted in Thornton, Colorado that also hosts a malicious website. The site contains a Trojan file that targets multiple platforms including Windows, Mac and Unix/Linux operating systems. This malicious program is able to drop different Trojan files, depending on the user’s operating system.

“The brazen use of a trusted app’s logo shows just how aggressive malware makers are becoming,” said Xuyang Li, CEO of TrustGo. “These fake apps not only put users’ data and privacy at risk, they can damage the reputation of respected developers. TrustGo continually monitors new apps uploaded to more than 185 marketplaces worldwide and is able to provide App Certification and Brand Protection services that alert developers when malicious clones and apps that falsely use their logos have been found.”

TrustGo’s SAFE App Reputation cloud services are updated immediately when new threats are discovered. Users of TrustGo’s free Antivirus app are automatically protected from Trojan!FakeLookout.A and thousands of other malicious and risky apps. For a detailed description of this new virus visit
