Continuing the line on sloppy email scams, a specific type is hitting one of my addresses. Spam is received regularly from the same addresses, having the same format. The attachments are created Matryoshka style, like in a previous post (archive in archive , finally containing a JS or DOC file).
The surprising things is that, even though they are very poorly executed :
- The spam filter is very bad at identifying it though. All of this is getting in my inbox.
- Over a 10 months period i’ve receiving the same kind of things from the same email address (different IPs though)
Sender IP address (from 2017)
Sender IP address (from 2016)
