UAT-10027 and Their Shitty Little DohDoor Backdoor

Oh for fuck’s sake. Look what the cat dragged in—another bunch of Russian or Chinese or whatever-the-hell APT wankers calling themselves UAT-10027, and they’ve decided that U.S. education and healthcare sectors need another royal shafting. Because apparently, these industries haven’t suffered enough already with their piss-poor security budgets and users who think “password123” is a fucking state secret.

This time the malware’s called “DohDoor”—which I can only assume is named after the sound I make when I see another DNS-over-HTTPS backdoor polluting my network logs. These clever bastards are using DoH to tunnel their command-and-control traffic, because nothing says “fuck you” to network defenders quite like encrypting your shady bullshit inside port 443 and blending in with every other HTTPS request. It’s like trying to find a needle in a stack of needles, except the needles are on fire and the stack is made of incompetence.

Education and healthcare—of course. The two sectors where the IT budget consists of whatever change they found behind the vending machine. You’ve got universities full of brilliant professors who can’t figure out that clicking “Enable Macros” on a Russian-language invoice might be a bad idea, and hospitals running Windows XP because “the legacy software won’t run on newer systems.” No shit, Sherlock. Maybe if you didn’t treat cybersecurity like a fucking line item below printer paper, you wouldn’t be getting rootkitted by every script kiddie with a GitHub account and a grudge.

The DohDoor backdoor itself is a piece of work—persistent, stealthy, and about as welcome as a turd in a swimming pool. It establishes persistence through scheduled tasks or registry keys (surprise surprise), exfiltrates data via encrypted DNS queries, and generally makes life miserable for anyone tasked with incident response. And trust me, cleaning this shit up is about as fun as performing a root canal on yourself with a rusty spoon.

Speaking of educational institutions and their security practices, it reminds me of the time I caught a professor running a Tor exit node on the university’s main file server “for research purposes.” I didn’t bother fixing the compromise—I just rerouted all his traffic through a honeypot serving nothing but goatse and lemonparty until he came crying to my office. When he asked why the network was slow, I told him it was the universe punishing him for being a colossal pillock. He stopped “researching” after that.
