Detailed Analysis

Spy/Sensyscan!SymbOS is a spyware for Symbian OS. Like Spy/PhotoSpy!SymbOS, it turns the phone into a camera surveillance device. When motion is detected, the phone automatically takes a picture and stores it on the phone (or memory card).
The spyware can be configured to send SMS, MMS or email to a configurable phone number when motion is detected.
This spyware's behaviour is borderline. There may be situations for which the application is legit, but, on the other hand, if installed without user's consent, it obviously threatens privacy, so end-users or systems administrators may want to ban it from their phone/networks.
