Intro:
The Gootkit is still broken, but now I’ve observed there is a change with the configured C2. Read ahead to learn more.
Artifact Source:
If you take a gander at the beaconing domains in the snip below, you can see that they do not contain xmlrpc.php.
Why is this interesting:
This is of interest because the last article we posted (“Gootkit is broken right now”, https://malasada.tech/gootkit-is-broken-right-now/), we showed a simple countermeasure to block requests to xmlrpc.php. xmlrpc.php could be legitimately used, but it’s easy to identify beaconing activity when a client IP has an excessive amount of requests to the same 10 URLs.
Are we amidst an upgrade? Will they be permanently removing xmlrpc.php from their C2? Stay tuned to this here website as we observe and report straight from the cyber front lines!
