We are seeing a new worm (new to us at least ;).
It is scanning random IP addresses on ports 135 and 445. It has
scanned on sequential addresses 4 times though (unless that was
a separate beast).
Once a machine is infected, several random ports are opened
and at least one of them appears to be attempting to send
On the few we scanned, port 1019 answers with:
220 an Cr3w Site^M^M
The one machine that we looked at had a registry
entry in HKLM../RunServices for "Windows Updater"
with a value of "svthost.exe".
Norton run on the machine picked up Welchia and
quarantined two files. Welchia never scanned on
port 445 though...
Any ideas as to what this is?
