indeed.  scanning for strings that appear to be associated
with the Concept Virus(CV) V.5, there is a tremendous
increase in bandwidth usage.  today alone i match:

/scripts:    18013
/_vti_bin:     1885
_mem_bin:     1916
/ms_adc/:     1945
/winnt/system32:    27648

bugtraq is starting to get in the preliminary reports
of this worm.  beware that infected host's home pages
contain a javascript that sends you to a page that
attempts to send you a copy of the worm.  fantastic, eh?

ugh...this is way more impact...a 128k ISDN customer running an NT/Win2k
box is at 100% BW, and my 2x T1's are at about 2x normal traffic for this
time of day, although still well short of capacity...apache server
processor load is WAY up just from the requests, and the logs are growing
like mad.

Has anyone else been seeing a dramatic increase in /scripts/.. NT worm
probes this morning?  We're seeing about 8000/second, starting around 9:15
Eastern time, to and from a wide variety of addresses.

affirmative.  i just looked at my logs, and it looks like
each probe tries a bunch of things.  i haven't seen much
on the lists, but i'm looking right now.

i'm pretty sure that the worm's attack phase starts on the 20th (which
of course, depends upon a correctly set system clock) and also that
attempting to execute something like /scripts/root.ext/c++ something
is involved.

i think that cert's website would be a good place to look.  i'm *not*
a security/virus chick, but i did host a talk by marty linder of cert
where he discected code red's activity and presented a summary.

cert is of course, http://www.cert.org.
