APT1-Related SSL Certificate Detected

critical Nessus Plugin ID 64688


An SSL certificate used in a malware-based command and control infrastructure was detected on the remote host.


An SSL certificate associated with the group known as APT1 was detected on the remote host. APT1's command and control infrastructure uses several self-signed certificates to encrypt communications in their command and control infrastructure. The remote host appears to be using one of these certificates, which indicates it may have been compromised.


Determine if the system has been compromised, restore from a set of known good backups if necessary, and investigate your network for further signs of a breach.
