Worm.Win32.Randon

Alert from Kaspersky:

"Randon" Threatens Port 445!
A new blended worm / trojan threat appears. Kaspersky Labs reports
registered infections at the hands of the new network worm "Randon".
Kaspersky Labs has already received several incident reports from both
Russian and the Netherlands connected with this malicious program.

"Randon" spreads via IRC channels and local area networks and infects
computers running Windows 2000 and Windows XP. To penetrate computer
systems the worm registers itself in the IRC server (or local area
network), scans for all present users and connects to victim computers
via port 445 and attempts to gain access by using a fixed list of the
most commonly used passwords. When "Randon" manages to successfully
break-in it proceeds to transmit to this system the Trojan program
"Apher", which then, from a remote web site, loads worm's remaining
components (a total of 13 files, including a full-fledged mIRC client
for work with IRC channels).
