HackTack is a backdoor that allows a remote attacker to take over a victim's machine.
The following registry key has to be removed first:
After rebooting the system the backdoor will not be loaded so it can be deleted easily and safely. '[Windows_directory]\CfgWiz.32.exe' is the backdoor program that can be deleted after the registry has been fixed.
When run the backdoor copies itself to the Windows directory as 'CfgWiz32.exe'. It adds a key to the registry in '[HKLM]\SOFTWARE\Microsoft\Windows\CurrentVersion\Run' called 'Configuration Wizard' that points to the backdoor program in the Windows directory. This way the backdoor will be started whenever Windows boots up.
When a machine has this backdoor any attacker can connect to it with the HackTack client. Using the client the attacker can do many things. Such as
- get general information on the machine (logged in user, system time, operating system version, etc).
- send messages to the user's desktop with different window settings
- take over the keyboard/mouse remotely
- send different event to running Windows processes
- do a shutdown/reboot/log off/power off
- steal stored passwords
- log everything typed on the keyboard (allows to collect more passwords and other sensitive data).
- browse the files on the machine, up/download files, run programs
- chat with the user on the other side (or with clients connected to the same machine).
- other things like, open/close CD tray, take a screen-shot, flip screen, etc.
F-Secure Anti-Virus with the latest updates can detect this backdoor.
