... Feels like deja vu. Didn't the US military just have this happen at its military exchanges... a month or two ago?

Yes, yes they did. https://www.militarytimes.com/news/your-military/2026/08/28/...

"ALL freezers went into defrost mode – ALL frozen food has spoiled".

I realized upon reading too this was the same Danfoss fridges that got hit for .mil bases in the US. There's probably a shodan signature to find them on the internet because HVAC people don't know about network security, and someone has a trivial exploit to access them due to shitty ancient embedded controller security in them.

Yes, not exactly "unprecedented." The news of Commissaries having their freezers hacked should have been a kick in the rump for everyone else with infrastructure needlessly connected to the Internet.

the sort of people doing this security posture definitely are not up to date on the latest security news...

It would take something truly monumental to make a local supermarket owner even consider the potential for their fridges to be an attack vector.

This was precisely my first thought upon reading. "Ah, yes - the attack that was PoC'ed against commissaries operated by the US armed forces a bit over a month ago."

Thanks! Macroexpanded:

I think the military commissary's freezers were hacked - https://news.ycombinator.com/item?id=49508506 - Aug 2026 (239 comments)

Yeah I remember that, and it seems like the military was very hush-hush about the cause. Now I wonder if they were hacked too.
