It would be useful if this exploit could be named and documented at least for one known instance - Regards, Lars Higham -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Richard D G Cox Sent: Monday, June 16, 2003 9:32 PM To: [email protected] Subject: Re: Spam from weird IP 118.189.136.119 On Mon, 16 Jun 2003 17:33:11 +0200, "Pascal Gloor" <[email protected]> wrote: | Getting SPAM from 118.189.136.119 relayed by rr.com ? | | this network is not allocated, nor announced.

Could you please check this? Our advice would be that the server-that-connected-to-you needs to be taken offline by the security people at its site (which you say is RoadRunner) and they should have ALL its disk(s) imaged for forensic analysis purposes. Our experience is that sites hit by this exploit will do basic checks on the server and claim it is uncompromised and "cannot possibly be sending that spam". Such a claim would be entirely incorrect. You would need to persuade them that something is wrong, which is difficult at the best of times. RoadRunner being involved in this case suggests this may *not* be the "best of times". -- Richard Cox
