| Description | Upon execution, this backdoor program drops a copy of itself as OCE32.WDEP in the Windows system folder. It creates several registry entries so that all files with the extension .WDEP are treated as executables. It creates another registry entry to ensure that it automatically runs at every system startup. It attempts to access a personal homepage found on www.geocities.com. This routine appears to be a means to notify a remote user that a system has been compromised. However, as of this writing, the said homepage no longer exists. It also creates the folder ETC in the Windows system folder, where it stores the files that it downloads from another Web site. This download routine looks like a means to update the backdoor program. However, as of this writing, the file that it attempts to download no longer exists. It is designed to open a random port on the compromised machine and waits for commands from a remote user. However, due to some bugs in its code, this backdoor routine does not execute successfully. This backdoor program runs on Windows 95, 98, ME, NT, 2000, and XP. |
