Can someone who knows something about this explain why they need about 3000 random gibberish hostnames for some simple “telemetry”? If my boss asked me to add “telemetry” to a piece of software I would send all the tracking calls to first-party-telemetry.companyname.com, and if I needed thousands of servers (!) for some reason, a simple load balancer or just round robin dns would do fine. This BS on the other hand looks like they know these thousands will get blocklisted and they plan to just rotate to a new set. The only way this could look more like malware would be if they used random-looking domains instead of just the subdomains.
