New redirector: www.nate.com
by David B Funk 22 Mar '05

22 Mar '05

Ugg, just ran across another open redirector abused in spam www.nate.com/r/XY12/target.domain where XY12 seems to be any combination of 4 letters and digits. Looks like some Korean ISP thingie. -- Dave Funk University of Iowa <dbfunk (at) engineering.uiowa.edu> College of Engineering 319/335-5751 FAX: 319/384-0549 1256 Seamans Center Sys_admin/Postmaster/cell_admin Iowa City, IA 52242-1527 #include <std_disclaimer.h> Better is not better, 'standard' is better.

Re: ZDNET redirecting to spammer websites?

Which domain are you referring to? zdnet.com should not be in SURBLs because it has too many legitimate uses. If we listed zdnet.com that would surely result in false positives. On the other hand viags.com and simply-rx.net should be listed in SURBLs, *and they are*. What's needed is for applications like SpamAssassin to parse the redirection correctly and check both zdnet.com and viags.com. zdnet.com should not match SURBLs, but viags.com should. QED.

It makes more sense to email him direct. Too bad I can't find he email anywhere! I guess its time to start telling the media about this open redirect.

Message to Kevin A. McGrail My apologies :(: for not getting back with you sooner. Other top-plate projects and out-of-state business, whew! I am very interested on the detailed information you have on implementing your tried-and-true methods for defending spam. I have a project to upgrade our McAfee e500 Webshield and SpamKiller to versions 3.x and it would be great to implement the solutions below. Our e500 sits inside our network, but should it sit in a DMZ and would this prevent receiving emails to invaliduser(a)thepantry.com? I would GREATLY Appreciate any detailed information you can spare!

Jeff: I think others looked at you wanting to run SA on Windows but I'm going to take a different tact since you are already running a linux box. In short, answer the question of how can I protect an exchange server from viruses & spam. First, I think you should look at Can-IT. They just released a "free as in beer" version for companies with less than 50 users. Otherwise the Can-IT Pro is a fabulous product and I always have to give them kudos for also releasing MIMEDefang as Open Source. http://www.roaringpenguin.com/ & http://www.roaringpenguin.com/anti_spam/free_canit.php Second, if you want to get into the nuts & bolts, you should run a linux box and install Sendmail 8.13.3 w/ Greet Pause & Bad Recipient Throttling, poprelayd-kam to blackhold the harvesting sites, then MIMEDefang, a milter written by the same people as CanIt. Have MD call SpamAssassin which implements SURBL. Add ClamAV or McAfee uvscan to the mix and you have great anti-viral features as well. Final step would be to configure LDAP on your linux box so you can "extend" the edge of your network to bounce bad emails ASAP. I've done this many many times and have instructions to help get you started if you want to take this avenue.

Spam Honeypot identification through SURBL
by Matthew Wilson 15 Mar '05

15 Mar '05

Jeff (and list), I'm worried that spammers can use SURBL to identify honeypot email servers by using unique subdomains. A spammer must merely send a unique subdomain URL to every address on their list, and if that unique subdomain is blacklisted in SURBL, they have identified a potential honeypot and will no longer send spam to that address/server. It is therefore my humble opinion that only the second-to-top domain name should be listed in SURBL, and not any of the subdomains. Thoughts? -Matthew Wilson
