Technical Details

Trojan:Android/Moghava was found being distributed in unofficial third party Android application websites in late 2011. Unlike most Android malware, it is not designed for monetary profit but for political ridicule.

Moghava.A.s malicious activity is triggered each time the device boots, activating a service named 'stamper'. This service waits for five minutes before searching for JPEG image files stored in the memory card, looking in the /sdcard/DCIM/Camera/ location in particular because that is where pictures taken from the device.s camera are stored.

For every found image file, it will superimpose another image on top of the original one. This routine will be repeated over and over in every five minutes, which effectively increases the size of the image file , and consumes the free space in the memory card.

This activity continues for a certain time interval before exiting.
