Technical Details
KabStamper.A is a harmful program that circulated in Japan during the AKB48 'election.' AKB48 is a Japanese pop group that consists of 48 members. The 'election' was held to select the most popular member who will become the face of the group.
KabStamper.A is distributed via trojanized applications that deliver news and videos about the AKB48 group. Malicious code in the malware is highly destructive; it destroys images found in the sdcard/DCIM/camera folder that stores images taken with the device's camera. Every five minutes, the malware checks this folder and modifies any found image by overwriting it with a predefined image.
