Possible scr worm

[john.ruff () us abb com]

Any idea what might be causing this aler tot be generated?  I realize it's POP3
traffic (probably someone's internet mail acct.), but is there something new out
there generating these alerts?  I've actually got about 3600 of these alerts
which just started Saturday(8/18/01).  Need more info let me know.

***One thing additional...the source is the same IP  address, the destination is
an user pc on my network but the TCP ports on the destination are increasing
incrementally with each attack (now up to 3700).  View sample from alert_fast
