RE: Spammer web harvesting tool countermeasures
by Jamie Scheinblum 31 Oct '97

This would be even more incredibly cool if you could track which hosts were fed which fake addresses so you could see which hosts were really doing the spam crawling. For example: When a host like crawler.spammer.com goes to the wpoison page, feed it a unique email address@yourdomain. Of course this would require that you tie the wpoison script up to your mailer. Re: polluting the legitimate search engines as well as the bad: webcrawler.com keeps an (almost) up-to-date list of good webcrawlers (as well as some bad ones). (http://info.webcrawler.com/mak/projects/robots/robots.html) This list is only 3 or 4 months out of date, so search engines like Microsoft's yukon would probably not be in the list. You could use this to exclude which engines get the wpoison page or not. Of course this gets back to the topic of "whitelisting" the internet because of the spammers.

RE: Spam Control Considered Harmful
by Paul Peterson 31 Oct '97

31 Oct '97

Im not sure of your logic about disabling the "invalid in-addr.arpa" filtering from your sendmail. I wouldn't do it for just one of my customers and expose the rest of my customers to spammers that intentionally try to hide themselves by faking a return address and/or masking their relay server with a bogus name. I would tell that one customer to have their constituent with no reverse DNS to get there setup corrected because: a. It is a proper and complete DNS config to have reverse mapping to your ip b. It makes all data originating from it accountable (not just spam but smurf attacks, DOS attacks, port scans/Satans etc.) to the organization/person responsible for the forward and reverse zone (if they match) c. It gives other ISP's and businesses the choice to filter or not filter. If one of us makes policy to make exceptions for a customer, then they tell other customers who tell other customers who tell other potential customers that an ISP should not filter e-mail on this premise. Let the 1 in 5 people in the Internet who are either lamers who don't know how to do reverse DNS properly or too lazy to do it keep their problems as their problems and not ours. Already there are a ton of TCP wrapper applications, FTP sites, telnet sites, Netscape U.S. Encryption pages for Navigator, etc that will not allow access with improper or non-existant reverse DNS entries. Would you consider not doing gethostbynames on your entire web server because one of your web clients wanted their mis-configured customers elsewhere in the internet to have that much faster access on web pages which would also give the rest of your customers stat pages full of IP's only ?? I wouldn't...... None of my customers have complained about us filtering the misconfigured in-addr.arpa people. 80% of my customers are business who exchange a lot of mail with other businesses on the net, maybe they don't care ? I dunno. As for responsible service providers disconnecting abusers, we have disconnected around 10 of them so far. I guess wer'e luck we haven't ran into a Spamford Wallace yet huh ? Just my opinion, thanks for tolerating it.

"Deepak Jain" <deepak(a)jain.com> said the following at 10/30/97 6:56 PM: >And wouldn't we, in turn, see some kind of problems arise with legitimate >search engines because of this? If you downloaded it and looked at it, you would have noticed that it follows search engine guidelines by adding the appropriate <META> tag to the HTML as well as the fact, that you can also use the robots.txt file to block it. Of course this also breaks down if spammer robots actually follow the rules...but how many of those do you think that there are? ;-) -jon Jon (no h) S.

Even on modems connections [snip] Because you happen to not be getting very much is no reason to believe that everyone is so lucky. Anyone who has been around for any length of time, posts or has posted to newsgroups, is the contact for any number of domains/ASNs/netblocks, or even hosts any number of domains gets bucketfuls. Often times, they work from old archives of Usenet as well. I've received garbage forwarded from old addresses I haven't used since '92 or '93. It is unrealistic to believe that one's expereince is sufficeintly representative to be able to generalize and define the scope of the whole problem.

I agree that spam is a problem but one that the industry can regulate on its own. We do not need state or federal legislation to control spam. If companies are really worried about it then lets get together and come up with a common solution. A solution that is as fair to the ISPs that only have 100 subscribers up to the UUNets and AOLs of the internet. I'll get off my soapbox now.
