Arrival Details
This backdoor may be dropped by other malware.
It arrives as a component bundled with malware/grayware packages.
It may be unknowingly downloaded by a user while visiting malicious websites.
NOTES:
This backdoor has several command-line components which are used to monitor the client and server connections, as well as modify the connection settings.
One of the components accepts parameters to change the controller and destination IP/port:
- {malware name} ctrlPort ServerPort
- {malware name} Port Dest_IP Port
- {malware name} ctrlIP ctrlPort Dest_IP Port
If the connection is successful, it can act as an intermediary component that forwards commands from the client to the server and vice versa.
If the backdoor's connection to the specified C&C server is successful, it can accept shell commands and execute them via command line, giving the remote user full control of the affected system.
