UNC3753: Vishing, Door-Kicking, and the Art of Being a Sneaky Bastard

Alright, listen up. The clowns over at UNC3753 have been busy, and by “busy” I mean running a greasy little extortion campaign against U.S. organizations using a delightful combo of vishing (that’s voice phishing for the non-hellspawn) and actual, honest-to-fuck physical intrusions. Yes, kids, sometimes the hackers don’t just hack — they walk their lazy asses right through the front door.

These assholes start with smooth-talking phone calls, pretending to be IT support, help desk heroes, or whatever other bullshit title gets people to hand over credentials like candy. Once they’ve sweet-talked or scared someone into compliance, they pivot to grabbing data, setting up persistence, and generally rummaging through systems like raccoons in a dumpster.

And when that’s not enough? They go physical. Badge cloning, tailgating, walking into offices like they own the place — because apparently basic security awareness is still optional in 2026. From there, it’s data theft, followed by the inevitable extortion: “Pay up, or we leak your shit.” Classy. Real fucking classy.

The whole campaign is a masterclass in abusing human stupidity. No zero-days, no wizard-level exploits — just phones, lies, and unlocked doors. It’s yet another reminder that the weakest link in security isn’t your firewall or EDR; it’s Dave from accounting who thinks every caller with confidence must be legit.

Defenders are being told (again, for the thousandth time) to train users against vishing, lock down physical access, monitor for weird logins, and maybe — just maybe — stop trusting random voices on the phone. But sure, ignore that and keep wondering how the fuck your data ended up in an extortion note.

Now if you’ll excuse me, this reminds me of the time I watched a “secure facility” let a total stranger into the server room because he carried a ladder and looked annoyed. No hacking required — just confidence and a prop. I laughed, then I cried, then I locked the door and revoked half the company’s access.
