Happy Belated Birthday, Sci Spam

Just a quick note to thank you all. Last year the daily figures were in the two million range for the IP DNSBL. We’re seeing slightly over double that these days. The domain name list is being queried even a little more than that, and the trend is clearly a growing one. Monthly totals are approximately 120M for both these days, in January and February.

Challenge/response backscatter is spam in itself

These posts are about ten years old, yet we still keep receiving boxtrapper spam.

We list it as spam. False accusations about forged sender addresses having sent spam are the only type of spam we list that isn’t Scientific Spam proper. This software (these types of software, including Spam Arrest, misconfigured amavisd-new, etc.) should simply not exist at all.

Happy Birthday, Scientific Spam

We started the operation on March 4, 2014, so it has been two years and a day. Thank you all who are listening and who are helping.

Adoption seems to be picking up. At the moment, daily lookups are in the two million range for bl.scientificspam.net and slightly over three million for rhsbl.scientificspam.net. During all of 2015 the RHSBL fielded 400M requests and the BL about 175M. In comparison, the monthly totals for January and February 2016 were 100M/month for RHSBL and 50M/month for BL, so we will be surpassing our 2015 figures by the end of April.

We appreciate the trust you are placing in us.

So much more Scientific Spam!

This might seem like an obvious thing to say, but here goes anyway. It recently occurred to us to look at what are all the target addresses any given Scientific Spammer is hitting on our traps. What started out as a meager collection measuring maybe a few dozen has quickly gone into the several hundreds this way – identifying new LHS in existing SciSpam trap domains and completely new addresses at new domains that are receiving any materials from known senders of SciSpam. 🙂

Happy Birthday, Scientific Spam – so much new spam

We fired up the list on Tuesday, March 4, 2014. It’s been an interesting year.

A while back, we opened up a bunch of new spamtraps and the flood has taken us by surprise. Some of these are spamming so intensely that they have even caught the attention of the 800 pound gorilla. Most of our subjects do not reach this level of spamming activity, however, which is why we plan to continue to exist.

The list is live :-)

Prior to October 26, this list has been mostly an academic effort.

ClouDNS statistics show how often any domain for which they provide the services has been queried. On October 26, the number of queries jumped from practically nothing to tens of thousands per day. We welcome our first major user, whoever you are. Please monitor your logs for false positives and get back to us if our listings are affecting anything else but scientific spam attempts to you.
