[Full-Disclosure] Heads up: Possible lsass worm in the wild

dropped file: %SYSTEM%/msiwin84.exe
remote process established to: lsass.exe
remote ip:4.x.x.x

note: file msiwin84.was not running

this appears to be a "blaster" type of worm working on the first and / or
second subset of the infected host to begin scanning for more hosts.
I have not completly unpacked the binary but here is some strings.

------------------ snip ---------------

based on the above, the worm / viri tries to connect to a IRC server.

anyone else experiencing this?
