Chinese hackers exploiting Dell zero-day flaw since mid-2024

Dell’s Latest Security Shitshow: Chinese Hackers Had Admin Access Since Last Summer

Oh, for fuck’s sake. Just when you thought it was safe to plug your backup appliance back in, Dell drops another steaming pile of vulnerability on our laps. And surprise, surprise—our friends over in China have been throwing a rager in PowerProtect Data Domain systems since at least mid-2024.

CrowdStrike, those poor bastards who have to clean up everyone else’s mess, stumbled across this clusterfuck while investigating some tech company that probably thought “appliance” meant “set and forget.” Turns out CVE-2024-37164—a catchy little authentication bypass with a CVSS score of 9.8, or as I like to call it, “nearly fucking perfect”—lets anyone with a keyboard and half a brain gain admin access to these overpriced data coffins.

What did the PRC’s finest do once they got in? Oh, just the usual Tuesday afternoon activities: created backdoor accounts with names like “sysad legit” (because subtlety is for amateurs), deployed TinyShell web shells, harvested credentials like they were picking fucking apples, and waltzed through networks like they owned the place. They even exploited CVE-2023-44191 on unpatched systems, because why stop at one gaping security hole when you can have two?

Dell, bless their hearts, finally got around to releasing a patch in October 2024, giving everyone a solid few months of getting completely owned. There were only 300+ of these appliances exposed to the internet, so no big deal, right? It’s not like data matters or anything.

The security advisory reads like a fucking apology letter written by a lawyer: “Update IMMEDIATELY.” No shit, Sherlock. Maybe next time don’t ship authentication bypasses in enterprise backup systems?

A user once asked me why we needed to patch the backup system during business hours. “It’s just backups,” he said. I explained that it was either that or let the Chinese government practice their data exfiltration techniques on our quarterly reports. He chose option C: complain to management. Management, being the absolute geniuses they are, delayed the patch. Three days later, we were explaining to the board why our “encrypted” customer database was being auctioned off on forums I can’t pronounce. The user? He got promoted. I got blamed.
