Critical Bugs Found in Delta Industrial PLCs — Because Apparently “Secure” Is Just a Suggestion

Oh bloody perfect. Yet another round of industrial control system faceplants — this time courtesy of Delta Electronics’ DIALink software, the thing that’s supposed to keep the goddamn factory humming instead of setting itself on fire. Some clever bastards found three critical vulnerabilities so big you could drive a forklift full of malware straight through them. Remote code execution, privilege escalation, the full “industrial apocalypse buffet” — pick your disaster flavor!

CISA’s waving the red flag, telling everyone, “Patch now before your plant becomes Skynet’s hobby project.” These glorious screwups came from Delta’s Smart Machine Suite — which, as it turns out, is apparently too smart to include boring stuff like proper authentication or memory checks. We’re talking buffer overflows and insecure data handling – the same 1999-level crap that should die in a fire already. At this point, if your industrial network’s connected to the Internet, you might as well just email your root credentials to every hacker forum and save everyone the trouble.

Delta’s released an update, because, surprise, it took a bunch of security researchers waving the “everything’s on fire” flag before they bothered. Fixes are available, but how many sysadmins will actually apply them before next century? Exactly. About as many as remember to change the default password “1234.”

So yeah, patch the bloody systems. Or don’t, and enjoy watching your production line get reprogrammed to spell “HA HA” in servo movements. Just don’t come crying when the machines revolt because you couldn’t be arsed to install one update.

Anecdote: Reminds me of that time a manager told me we didn’t need to patch a “low-risk” control system. Two days later, the thing started belting out Christmas songs in February, unplanned, at 120 decibels. Pure art.
