Technical Details



Backdoor:WinCE/PhoneCreeper is a publicly available monitoring program designed to run on mobile phones using the Windows Mobile 5 to 6.5 operating system.

On installation, the targeted phone may be remotely directed via specific SMS text messages to perform a wide range of actions, all of which are hidden from the phone's user. These actions may or may not result in the user incurring higher phone charges.

A B variant of PhoneCreeper is also available that fixes some issues of the A variant.

PhoneCreeper can be installed by inserting an SD card containing the program's files into the target phone. On installation, the program does not appear on the installed programs or running programs lists.
