RE: Matt Wright FormMail Attacks

I've seen it be very successful. Without going into detail, there's a script out there that spammers seem to be passing
around that automatically formats and submits data to formmail.pl on remote boxes.  Sure enough... it works like a
charm.  If you are curious about the script they are using, just attach a sniffer to your inbound wire and enjoy.

I tried finding some information on these incidents this morning, after
noticing them in my logfiles.  Very little info is out there (at least,
reachable by search engines).  I found two messages, one in the
incidents.org archive and one in the securityfocus archive.  They didn't
provide much information though.
 My guess is one of the following: 1) Someone looking to send spam through
someone else's webserver. (Seems like that would be very inefficient).  2)
Someone looking for a new exploit, maybe testing the waters for a new worm.
3) Someone looking for a way to "forge" emails.  make it look like it came
from an email address of the affected domain.  The email header would go
right back to an address in the "forged" domain.

Any thoughts?  Maybe someone with the formmail.pl file can tell us what
happens if this incident is successful.

Morning,
 
just found "Matt Wright FormMail Attacks" as number 5 in 'Top Five' on
aris.securityfocus.com. 
I've sent dozens of alerts to ISPs about formmail.pl incidents but still
having the probes from the same subnets (addresses) for few months already.
Looks like people are not serious about this probe. Is anybody know why
number of formmail.pl attacks is growing? May be it is a part of SPAM
toolkit or some very popular tool?

Dmitri Smirnov, SSCP
