Threat: Backdoor.Win32.VB.awm
Vulnerability: Authentication Bypass - Information Leakage
Description: The "Cryptech Heat" malware listens on TCP port 3786 and has an option to set an remote access password. The malware also runs a keylogger, we see imports for GetAsyncKeyState, GetKeyState, keybd_event and GetActiveWindow modules. Third-party attackers connecting to the infected system can use any password and will essentially see anything the victim types, searches or programs they run. As all information is piped out to whatever remote endpoint is connected.
