| Description | This backdoor enables remote users to access compromised machines. It works on the Client-Server principle. Its server component installs on the target machine, where it listens to a port and waits for a connection from its client counterpart. When a connection is established, the client can send remote commands to the server, which executes these commands on the compromised machine. This malware configures the registry so that its copy is executed each time a TXT file is opened or a EXE file is run. |
