Teams Phishing? Color Me Fucking Surprised

Oh look, the wetware has done it again. Some absolute genius in marketing decided that clicking “Accept” on a random file from “Microsoft.Teams.Secure.File.Share.exe” was a brilliant fucking idea, and now we’ve got backdoors darker than the coffee I haven’t had enough of this morning.

Apparently, the cyber-scum of the week are waltzing into Microsoft Teams chats—either by compromising some poor bastard’s account or spinning up external tenants that look almost legitimate—and dropping malware payloads named DarkGate and MediaDown like they’re handing out candy at a convention. And your average employee? They’re downloading this digital syphilis faster than you can say “IT security policy.”

The attackers are abusing Teams’ guest access and external sharing features because why the hell not? Microsoft made it as easy as possible for any random twat to send your precious intellectual property straight to a C2 server in some Eastern European basement. The files come with convincing names like “Organizational Changes” or “Bonus Payouts” because nothing gets a salaried drone’s finger twitching toward the mouse quite like the thought of free money.

DarkGate sets up shop with remote access capabilities, keylogging, and credential harvesting—basically everything short of physically kicking your users in the bollocks. MediaDown is the supporting act, dropping additional payloads because apparently one infection isn’t enough for these greedy sons of bitches. And the best part? It all looks legitimate because it’s coming through Teams, that blessed platform you’ve forced everyone to use instead of actually secure communication methods.

The fix? Block external Teams access, enable stricter file policies, and maybe—just fucking maybe—educate your users that a file from “TotallyLegitCorp.external” probably isn’t carrying the quarterly reports. But who am I kidding? You’ll do none of it, get compromised, and then blame the firewall.

Anecdote of the Week: Back in my mainframe days, I had a user who insisted on bypassing the proxy to “speed up downloads.” I didn’t bother fixing his machine when it got infected. Instead, I rerouted his traffic through a honeypot that served him nothing but Barney the Dinosaur images at 1 byte per second. He complained to management; I showed them his browser history. He doesn’t work here anymore. Neither does his dignity.
