OFF-TOPIC: CBS Forgery Scam
by Rob McEwen 14 Sep '04

14 Sep '04

OFF-TOPIC: CBS Forgery Scam (forgive me Jeff) I've studied this thoroughly. I can say 100% beyond a shadow of a doubt that this is a forgery propagated by CBS. Has anyone been following this? Does anyone doubt what I just said? Rob McEwen

ns15.surbl.org is down
by Jeff Chan 13 Sep '04

13 Sep '04

Bjorn Jensen let me know that ns15 is down with a hardware failure and probably won't be back up until Monday. I have temporarily substituted ns16's IP address for it and commented it out of the "k" name server round robin. DNS should be operating normally as a result. Jeff C.

Probable FPs
by Ryan Thompson 13 Sep '04

13 Sep '04

I found the following domains listed in a ~20K ham corpus from the last couple of days: Domain Age in Days Score (#msgs) attac.biz 826 -3.3333 (1) blah.com 3462 -3.3333 (1) chartshop.com 2275 -3.3333 (1) publicaster.com 965 -3.3333 (1) resortvacationstogo.com 1849 -3.3333 (1) send4fun.com 1681 -30.0000 (1) surveymonkey.com 1770 -3.3333 (4) topcities.com 1926 -2.5000 (1) whtirc.com 246 -3.2491 (1) whtradio.com 196 -2.3630 (1) Full GetURI output: http://ry.ca/geturi/runs/20040910-fps.html Quick look: attac.biz Looks real fishy, but appeared in some travel newsletter. Related to eturbonews.com. Maybe de-list, but don't whitelist. blah.com This was in a ProFTPd mailing list message "how do I set up a virtual host for "blah.com". chartshop.com Astrology.com newsletter. People really do sign up for those things. surveymonkey.com AFAICT, mostly legit surveys send4fun.com Jokes, example was person to person links topcities.com Free subdomain host. whtirc.com, whtradio.com Web Hosting Talk newsletter. Yes, it's legit. publicaster.com Used in some legit newsletters/mass media resortvacationstogo.com Looks mostly legit, and they've been around for 1800+ days without any NANAS hits at all. Related to vacationstogo.com. With the exception of attac.biz, I'd say whitelist the lot of these, unless anyone knows some reason why not. :-) The *real* cool part is GetURI (devel version) actually processed all of these messages in one run, producing ~4MB of output. Mozilla, on the other hand, crashed rather unceremoniously. Be thankful I re-ran on only the messages that generated the FPs. :-) Also, if someone wants to go through the *other* domains (i.e., those on a grey (not blue) background), there are probably quite a few other whitelist candidates there.

The link below was included in an e-mail announcing the Seattle Career Fair by National Career Fairs (http://www.nationalcareerfairs.com/). I found no NANAS listing for this domain. http://www.ncfmail1-MUNGED-.com/lt/t_go.php?i=429&e=aGVhdGhlcnJAdmFsbGV5aW5… This link redirects to a registration page on the National Career Fairs web site.

No SURBL hits on issip iadb
by Jeff Chan 12 Sep '04

12 Sep '04

I checked all the SURBL blocklist records against iadb and got no hits. http://www.isipp.com/iadb.php (This is with checking domains against iddb, then taking the IP addresses resolved by iddb and checking those against iadb.) http://spamcheck.freeapp.net/iadb-check Against the entire whitelist (but excluding the .us geographic parent domains), I got one hit: > thisistrue.com: 127.0.0.2 > thisistrue.com: 127.0.1.255 > thisistrue.com: 127.3.100.10 > thisistrue.com: 127.0.0.1 Due to the low hit rates iadb may not be useful for us yet in checking for fps. Perhaps when it has more records, it will be. Or perhaps there isn't much overlap between our spammers, our whitelists and iadb, which is also a reasonable answer. Jeff C.

Software spam with recently registered (fake?) sender domains
by Joe Wein 12 Sep '04

12 Sep '04

In recent days I've seen a lot of pirate software advertised in spam that uses a sender address of the form "Firstname1 Lastname1" Firstname2Lastname2@suspectdomain where suspectdomain is a very recently registered domain (late August-early September). Previously software spammers used all kinds of fake sender domains, but non they had registered themselves and not specifically recently registered ones. Has anyone else noticed this and has any thoughts about it? I wonder if spammers are buying lists of recently registered domain names off registrars in order to poison domain blacklists?

Re: [SURBL-Zones] Lowering TTLs

OK I'm changing the TTLs on all tue SURBL lists to 25 minutes which is a midway point between the 20 minutes I was going to try for SC and the 30 minutes we proposed for the rest of the lists. 25 minutes is also a good sampling frequency to capture data that has a 1 hour characteristic frequency. This is mainly an experiment to see what effect it has on DNS traffic. If the traffic on SC is not a lot lower, I'll change it back to 10 minutes. If the traffic on the other lists is not a lot higher, I'll leave it at 25 minutes. Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

I can't tell where you are on this subject now Jeff :) Are you saying , that if we get really good data like what was in my original post, and we keep the data in the 90th percentile area, then we might possibly be able to list the IP hosts and have SURBL check against it? If so..I'm up for that. Granted it would take a little more research then just a domain listing, but I think the benefits are very good. Especially if we keep it only high ranking IP offenders. I mean, we may add less then 50 IPs a year? Just the really nasty spammers. Anyway, its been a great discussion. If we've learned anything in the last 24 hours, its that the Patriots defense needs some work against the run game ;) --Chris (Go Tom Brady!)

Whitelist all Bonded Senders?
by Anne P. Mitchell, Esq. 10 Sep '04

10 Sep '04

> Since you're checking out Bonded Sender, can you request a zone > transfer or rsync from these guys too so we can check their data? > Note that the Bonded Sender status of a sender (are they or aren't they) is incorporated into the IADB data. The same for Habeas status, and whether they publish SPF records, among many other things (the complete list of information one can glean from an IADB lookup is available here: http://www.isipp.com/iadbcodes.php) As Jeff notes, you can sign up to query here: http://iadb.isipp.com/iadb_query_sign_up.php If you have any questions, or suggestions, please feel free to contact me personally.
