August 2017 in Spamtraps: ESPs
ESP spam seen in spamtraps, August 2017
My schedules are really falling apart… but at least I got it out before heading off for Toronto! Yay! Looking forward to the meeting.
The percentage of ESP sent mail vs all mail seen in the spamtraps was 2.0%, which was down 22% from August. The amount of all mail was up 22%.
The top ten looks familiar, but there is a new contestant in the top 30 (see “relative badness”) – who immediately made it to the top of the relative badness list, as well. The Scandinavian affiliate spammers found DoctorSender; over 90% of what they sent is 10 top subject lines, all in Swedish, 95% is 20 top, now with Finnish included. Almost all of it came from just one of their many ranges, 185.121.235.0/24.
Bubbling under the top 10 this month: Sparkpost (1.9%), Mapp Digital (1.6%), Bronto (1.5%).
