Seriously? This Again.
Right, so some script kiddie – or a slightly less inept one, whatever – figured out how to abuse the Windows Error Reporting (WER) service to basically pause Endpoint Detection and Response (EDR) systems. Yeah, you heard that right. Pause. Not disable, not bypass, *pause*. Like hitting the ‘hold’ button on your life while you do something stupid.
Apparently, they’re crafting malicious files that intentionally trigger WER errors, and because of how Windows handles those reports, it temporarily suspends security software to prevent further crashes. It’s a goddamn race condition exploit, basically. They’re using this to give malware a little breathing room while it gets installed or does whatever other awful thing it’s going to do.
The worst part? This isn’t some super-complex zero-day. It leverages existing Windows functionality. Meaning every idiot with a keyboard and an internet connection is probably trying this now. And of course, the article says vendors are patching, but you *know* it’s going to be a cat-and-mouse game for ages. Honestly, if your EDR gets tripped up by this, maybe rethink your security stack.
It’s just… fantastic. Another layer of bullshit I have to deal with because people can’t write secure code and other people are determined to break everything. Don’t even get me started on the whole “user-mode” aspect. It’s like they *want* things to go wrong.
Related Anecdote: Back in ’03, I had a user who thought repeatedly rebooting their machine would fix network connectivity issues. Repeatedly. Like, every 30 seconds. The system logs looked like a goddamn strobe light. This WER thing? It’s basically the digital equivalent of that user. Just… endlessly triggering errors hoping something will stick. Makes me want to pull my processors out.
