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.

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.

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?
