ESP spam seen in spamtraps, October 2018

The percentage of ESP spam was 3.0%, down from 3.2% in September. The total amount of mail in this trap collection was up 16% from September.

There’s a new player on the list again. Ediware is a French email service provider that has been around since 2001. This is the first time ever they have made this list in any capacity, and it’s straight to the top 10. During October 24 from 5 pm to 8 pm CEST they had a malware/botnet/whatever infestation spamming “fix your wifi”, “desktop microscope”, “heating gadget” etc. To their credit, they got on top of it quite quickly, in four hours the problem was completely curbed, but while it was going on, the volume was huge. Any other stuff from them amounted to 0.4% of the total – no wonder we don’t usually see them.

Salesforce is so much ahead of SendGrid this month I would have expected to see something unusual from them. But no, it’s the same old players, none of whom are sending anything out of the ordinary.

SendGrid really need to get rid of Advisor Perspectives. Like, really. And so do MailChimp, for that matter.

Bubbling under this month: Mapp Digital (2.1%), Adobe Campaign (2.0%).

July to September 2018 in Spamtraps: ESPs

July to September 2018 in Spamtraps: ESPs

We had an unexpected participant in Hobsons, who traditionally send effectively nothing to us, only just about enough for us to have recognized that they even exist. It appears their network space is shared between the ESP and some other branch of their operations. The servers of the non-ESP operations were misconfigured on April 10 shortly before 8 pm UTC and started spewing out backscatter (bounces of spam to the forged sender addresses). This went on until 9/11 @ 11 am UTC, peaking in July.

With Yesmail, the money mule spammers (subjects: “New offer”, “New vacancies in our company”, “Interesting work”, “Staff Wanted”, “Good day!”, “Hello!”, “Interesting offer”, “Welcome to our company”) started appearing in April, peaked in July, and were effectively out by September. The numbers of this type of spam on any other ESP platform are never measured in more than the single digits.

Worst senders:

  1. SendGrid: Advisor Perspectives, by a margin of more than 2x to the next contestant, month after month (with a slight nod in the general direction of Airbnb in July)
  2. SMC/ExactTarget: Kohls (only barely), with Marcus Millichap popping up in September
  3. MailChimp: Advisor Perspectives (WTH?)
  4. Oracle: Nordstrom (only barely)
  5. Mailgun: The Italian affiliate spammers (see previous blogs)
  6. Yesmail: After the money mule trash, mktgdillards.com
  7. Amazon SES: jobalert123.com
  8. CheetahMail: shopbonton.com, loft.com, emailtuesdaymorning.com (all almost below the noise floor)
  9. Constant Contact: 123dj.com (only barely)
  10. IBM: tjx.com, renewlife.com
  11. Mapp: conservativeintel.com
  12. Epsilon: DICK’S Sporting Goods, Inc.
