DragonForce: Because Abusing Microsoft Teams Was the Next Obvious Shitshow

Alright, gather round, kids. The DragonForce crew — a bunch of enterprising shitheads — figured out they could hide their backdoor command-and-control traffic by abusing Microsoft Teams infrastructure. Yes, that Teams. The one your users leave open 24/7 while ignoring security training and asking why the VPN is “slow.”

Instead of running noisy, obviously malicious servers like amateurs, these assholes piggybacked on Microsoft’s own trusted relays. Their malware chats home through legit-looking Teams traffic, neatly blending in with the endless stream of GIFs, meetings-that-should-have-been-emails, and corporate bullshit. To defenders, it looks like normal Microsoft cloud traffic. To attackers, it’s a perfect fucking disguise.

This turns security monitoring into a bad joke. Block it? Congrats, you just broke Teams and now HR is screaming. Allow it? Fantastic — you’re letting attackers run C2 traffic right through your firewall wearing a Microsoft badge and a smug grin. It’s another reminder that attackers love abusing trusted platforms because we keep whitelisting them like idiots.

The takeaway (since some people need it written in crayon): attackers will always abuse whatever cloud service you trust the most. Today it’s Teams. Tomorrow it’ll be something else you swore was “safe because Microsoft/Google/Whoever runs it.” Defense teams now have to detect malicious behavior inside allowed services, which is about as fun as diffing logs at 3 a.m. while management asks if AI can “just fix it.”

Now if you’ll excuse me, this reminds me of the time I blocked a “trusted” cloud IP range and took down half the company for six hours. Management called it an outage; I called it an educational experience. Nobody listened then either.
