APT1-Related SSL Certificate Detected

critical Nessus Plugin ID 64688
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

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.

Solution

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.
