Hash: SHA1

Couple things to look for.

1.connections to IRC
2.are the names in the IRC connection random and look generated
3.time intervals
4.does it appear that the machines on the network are getting patched
if you run a vuln scanner against them and once reported vuln?

This should point you towards if its a bot/ worm. A lot of the bots use
the lsass vuln.

best of luck. giles
