Android Malware Stays Hidden

There is an Android malware out there that makes use of steganography to hide the control parameters for rogue code.

Steganography is the technique of hiding messages within something else, in this case, an icon file. And, with more users in the manufacturing automation industry using Android-based smartphones, it makes sense to keep a sharp eye out for any kind of malware loaded onto your system.

Researchers at security company F-Secure first realized Android malware was making use of steganography when they came across certain lines of code.

Further digging revealed more code, and it soon became clear the image file they came across was the icon file bundled with the rogue application.

The hidden information can control how and when premium rate SMS messages are sent from the victim’s handset, which, as far as the bad guys are concerned, is the primary purpose of the rogue application.
