Korgo Worm Detection

critical Nessus Plugin ID 12252

Language:

Synopsis

The remote host is probably infected with the Korgo worm.

Description

Nessus found that TCP ports 113 and 3067 are open.
The Korgo worm is known to open a backdoor on these ports.
It propagates by exploiting the LSASS vulnerability on TCP port 445 (as described in Microsoft Security Bulletin MS04-011)

** Note that Nessus did not try to talk to the backdoor,
** so this might be a false positive.

Solution

Disable access to port 445 by using a firewall. Additionally, apply Microsoft MS04-011 patch.
