OT: What's up with spamcop...
by Patrik Nilsson 26 Apr '05

26 Apr '05

Once again, outgoing IPs for bulk.scd.yahoo.com, sourceforge.net, etc, are getting listed on spamcop. I thought they had got past these kind of obvious FP problems. Anyone know what is going on? Patrik

The name servers were removed from the registration data listings, but the "Updated Date" was not changed. I filed complaints at the internic about sevral of them. Given that they now (at least the ones I've checked) have no name servers, they are eligible for nomination to rfci's "whois" list (if I have been there first), and subject to delisting by filing the form at the internic (i.e. wdprs.internic.net - just fill out the section of name servers, noting that they have none). One of them, jocosehnajj. com, is a brand new registration, it didn't show up at the internic this morning, nut by a good guess, I found it at whois.directnic.net. Paul Shupak track(a)plectere.com

XS hits
by Paul Shields 24 Apr '05

24 Apr '05

Below are some stats from our incoming mail since midnight 23/04/05. I'm not going to go into too deep an analysis as it's the weekend and I'm too 'tired' to do that ;). Total nbr of messages with at least one ??_SURBL hit over the last 22 hours was around 1.4 million. The counts below show how many triggered as 'spam' ("result: Y"), and how many didn't trigger ("result: \."). This is based on our Spam Assassin default threshold of 8, but we have many custom rules so spam threshold is really only meaningful to our config - YMMV ;). We don't currently block or tag via SURBL/RBL at the MTA layer - everything goes through SA. XS popped up reasonably frequently in all SURBL hits - and we had 10456 XS spam hits where it wasn't listed in any other URIBL (unable to say how many false-positives out of that list, but our default tagging threshold is high in SA and FP's are vanishingly small). Anyway - make of it as you will. SURBL rocks anyway - XS *may* be a useful addition.

It's the top 97th percentile of hits, which only gets about a hundred more new records (domains and IPs) than we already have in SURBLs. We can crank that up later when we get the FP issues nailed down better, though improved processing techniques. > However, my own experience, so far, > is that absolutely no "zero-hour" spams have been caught, Yes, that's because the new URI hit counts must overcome the mass of earlier reports. There may be smarter ways to organize this, but simply lowering the threshold of inclusion (e.g., going to the 98th percentile) would get more on the list sooner. > but very many Spamcop > reports (about 1/2 hour later) do trigger; So I have to agree with the few who > have suggested a much more aggressive decision about when to add.

Off the top of my nogging, I've seen the major guys be about 1-3 days from registering. However...... I also saw a pattern a few spammers using ones registered 3 months prior. This is when I began to theorise that there was possibly a spam domain service. Someone simply registering domain names full time, then selling them out to other spammers. I started researching the idea, then got busy on other stuff. When things settle I'll try to pick back up on the research. Sorry I don't have any hard data for you. --Chris

XS FP
by Daniel Kleinsinger 23 Apr '05

23 Apr '05

XS tagged an email from peak.org. I can't forward the email, but peak.org seems to be an ISP in Oregon. Also, the only place peak.org appears in the email is in a section of the email showing envelope information from a previous email in the reply chain. >Date: Wed, 20 Apr 2005 03:54:43 -0700 (PDT) >Subject: Re: blah blah blah blah >From: businesscontact(a)peak.org >To: "someone" <someone(a)mindspring.com> Does that look like a URL to the URIBL plugin? I'm using SA 3.0.2. That's been the only email tagged by XS that had a final score less than 10 so it was easy to spot. Daniel

Re: [SURBL-Discuss] Testing: xs.surbl.org (CBL Data)
by Jeff Chan 23 Apr '05

23 Apr '05

Chris Barton of McAfee spotted the following FPs in the XS data. Looks like they could all be avoided by a date of registration filter where domain registrations older than say 1 year were excluded. Anyone have feedback on Chris' findings? Engineering a date of registration engine is probably my next project. It could be used as a general tool within SURBLs. (If anyone has an existing tool to share, it could definitely help.) Jeff C. __ Some possible xs. FP's for you... ets.org NANAS 27 - mostly mailto's by the look of it. no SBL/XBL - no spamcop Created On:10-Oct-1994 javaworld.com NANAS 7 - all old, no SBL/XBL no spamcop Created On: 1995-Nov-22 disneyland.com - no brainer? 91x.net - NANAS DODGY - Looks like a URL service - http://91i.net/index.shtml - Also on multi. - no spamcop - No XBL/SBL - Creation Date: 19-sep-2003 atspace.com NANAS 12 - host with a few small issues - look ok - NO XBL/SBL/spamcop - Creation Date: 16-jan-2004 dante.net - NANAS 18 - ISP with a few issues - look ok - NO sbl/xbl/spamcop - Created 1993 epolitix.com - NANAS 0 - no xbl/sbl/spamcop - look ok - created 1999 hopto.org - NANAS DODGY but it belongs to no-ip.com who are cool. kit.net - NANAS VERY DODGY - Looks like a URL service though. Listed on multi. created 1997 no xbl/sbl/spamcop I wouldn't like to call it ham at this point as it appears to have a hosting issue atm. peak.org - NANAS DODGY - Looks like an ISP with a few issues to me, nice spam filter logo - no XBL/SBL/spamcop created 21-Dec-1994 qq.com - looks like a portal rather than spammers - no xbl/sbl - NANAS 134 - created 04-may-1995 researchandmarkets.com - NANAS 18 - no xbl/sbl/spamcop - created 1992

I have this zone loaded on my three name servers - I tried to e-mail Jeff, but his mail server incorrected performed a SPF query against an internal IP in the mail headers rather than against the IP which actually connected to surbl.org to deliver the message. David
