Could be a variant of the Win32/kibuv.b worm

Maybe it scans for the LSASS buffer overflow. Is there a FTP server on
7955? a backdoor on 420?

This worm also tries to connect to a IRC channel via port 6667

I've been finding a few compromised Windows systems on our campus that
have a random port open with a banner of "220 StnyFtpd 0wns j0".  All
the systems seem to be doing SYN scans on port 445 and LSASS buffer
overflow attempts.  Anyone know what worm/bot is doing this?  I don't
have access to these machines so I can only get a network view of what
the systems are doing. 

Thanks, 

Ryan
