DeadLock Ransomware: The BYOVD Clusterfuck Nobody Asked For

Oh, bloody fantastic. Just when you thought the internet couldn’t get any more of a clown fiesta, along comes some absolute genius bunch of cyber-muppets running a shiny new ransomware campaign called DeadLock. And, of course, they brought their own goddamn vulnerable driver to the party—BYOVD style (Bring Your Own Vulnerable Driver, for those fortunate souls who still have some faith in humanity).

So, here’s the scoop, minus the marketing fluff. The threat actors behind DeadLock aren’t content just encrypting your files and ruining your day—they’re also using this neat trick where they load a vulnerable driver to unload security software faster than you can scream “WHERE’S THE BACKUP?”. That’s right, they’re leveraging signed but insecure drivers to give themselves kernel-level access. Because apparently, the universe wasn’t cursed enough already.

The bastards are chaining together this BYOVD loader with the ransomware payload, getting system-level privileges, shutting down defenses, and locking up your machine tighter than a miser’s wallet. Cisco Talos tracked these delightful little digital arsonists and found the whole thing’s a finely crafted piece of chaos: a loader to disable protection, an encryption engine to wreck your data, and some nasty comms infrastructure to keep things running smoothly while they screw you over from a distance.

If you think that’s bad, they’ve even been using the kernel-level shenanigans to dodge modern security tools like it’s some kind of twisted Olympic sport. The report’s basically a masterclass in how to ruin someone’s day, complete with driver abuse, process termination, and all the usual ransomware bullshit. So, yeah, if you thought your antivirus was going to save you — that’s adorable. Good luck patching drivers that even Microsoft’s forgotten exist.

In short: patch your bloody systems, stop running untrusted crap with admin privileges, and for the love of all things digital, keep your backups offline. Because these cyber-gremlins don’t sleep, and apparently neither do I—thanks to yet another dumpster fire of Windows driver vulnerabilities.

If you actually want the full nerdy breakdown (and I mean it’s a doozy), here’s the link where the Talos folks kindly dissect this mess:

Reminds me of the time some idiot user called me because their “computer just shut off by itself.” Turns out they thought “clicking the .exe from that unknown email” was part of a system update. I told them updates don’t usually encrypt your damn tax documents. But sure, Karen, it’s probably Microsoft’s fault again.
