I think the military commissary's freezers were hacked

As someone who spent over 20 years active duty, and spent a ton of my career in the IT, security, etc. side of the house:

Unlikely to be a hack, more likely to be a misconfiguration or update sent incorrectly.

That said, the timing of the disclosure and the issue are rather concerning.

Regarding the highest value targets to hit with an attack like this, you would want to target Guam, Hawai'i, and other isolated overseas locations where this would have ripple effects in the local economy. Guam specifically would cause catastrophic supply shortages, since DeCA probably supplies around 50% of the groceries on that island (that's a WAG based on my time there).

A couple years ago I worked on a service that had to communicate with a Siemens S7-1500 PLC. Based on my experience with that project, none of what I’ve read recently about unsecured industrial PLCs is surprising.

I opened Siemens TIA Portal and PLCSIM for the first time and thought “wow, I didn’t think the Windows 95 GUI library was still supported.” None of the PLC contractors we had hired knew how to enable TLS on the thing (user/pass eg admin/admin was their usual). Anecdote: I once spent hours reading the docs and clicking around trying to get it to accept an SSL certificate signed by a real CA and it wouldn’t go, but it accepted one I self-signed in openssl.

In all fairness, the people who are experts in the field of Siemens PLC programming are usually mechanical-ish engineers and security is not in their skill set or on their mind.

The author doesn't really claim it was a hack, just that it is a possibility. But they are charging down the path of the potential hack before asking the more obvious question: How many refrigerators exist in the military at all? And of those, how many are having problems?

Because a half dozen a day sounds plausible as standard maintenance issues, as the author acknowledges. If it were a hack, I'd expect something like 50% of them to have problems. But not knowing how many there are, I don't know how significant these incidents really are.

First let's acknowledge that this could very easily be a misconfiguration issue.

But, I'd be a lot more inclined to that idea if it wasn't for how they failed: they started a defrost cycle that turned the freezers into heaters, spoiling the food quicker. And the failure happened overnight, delaying discovery of the problem.

It could be just a compounding of bad luck. But an attacker with access to the specs for the freezers might be aware of how long they would stay cold after being simply shut off.

Probably not, but my closest bet would fall to Hanlon's razor:

I was curious if this was continued evidence of poor appropriations and upkeep or what... I do see "U.S. military commissary refrigeration maintenance, equipment replacement, and physical infrastructure are funded through the 5% commissary surcharge paid by customers at checkout rather than direct congressional appropriations."

So, perhaps the first place would be to follow the money - are these being repaired at the proper rate? Is this repair outsourced to third party vendors? (my guess). Is this gonna end up being the McDonald's Ice Cream machine all over again?

Really though, Hanlon's would be much easier to believe this is yet further ineptitude by those who run things (I am not going to claim malfeasance/malevolence, except a general sense of such across the board by this admin).

Since I'm not on the inside, anything I have to say would be speculative, just like the above, or the author themselves (I have no idea who it is, and perhaps they have a better beat on the ground with regards to this), but it just falls in line with "we're running out of missiles" and "sailors attempting to kill themselves".

We're so insistent on being #1, we can't admit we're in a society that is falling apart (and again, it may be the case that this IS a hack, but if I were to place my bets...)

Ineptitude, lowest cost players, etc "efficiency" indeed. You get what you pay for, and I guess 5% don't pay for a whole hell of a lot these days.

Howdy y’all, author here. Just discovered this thread after wondering why Hacker News was a linked views source to my silly little freezergate braindump.

Wanted to offer a few clarifications:

I’m not a cybersecurity expert; I’m an investigator (in a totally different field), and this was essentially me following a weird thought to see where it went. My background is in natsec so that’s where my mind goes. There have since been at least dozens of additional freezer outages reported in a similar pattern, but I'm refraining from calling/tracking down every individual weirdness based on a Facebook comment at this point since there are much larger outlets with journalists more proficient than I covering this by now. Another interesting thing - There are numerous freezers and fridges within base stores, not under the control of DeCA/DoD, and none of those appear to be impacted.

I completely agree that a bad update/configuration or other shared technical failure may be the much more boring answer. The interesting part to me is that potentially hundreds of varying systems can converge upstream into common monitoring/control infrastructure. Anyone on this forum probably understands that, however IoT was something that was a relatively new concept when I was in school, and my degrees were somewhat relevant. The average person is blissfully unaware how expansive (and how much work behind safeguarding) the IoT is.

Also, since it came up: Yup. Human written. I’m pretty firmly anti-AI as a writer and also just, like, societally. I'll be sure to add some sort of footnote detailing my ai usage at the bottom of future public facing work, because I too detest reading (or questioning if what I'm reading is) slop. Minimal LLM used for understanding technical concepts and what the fuck fridge norms are…The weird formatting, excessive bolding, neurotic parentheticals, and rant energy are, unfortunately, totally my own. Sorry guys.

This was my first ever public post and intended audience was ~ 10 friends forced to read my diatribe, not thousands of strangers very validly raising questions I am not smart enough to answer myself. Appreciate the discussion and will be further educating myself on some of the points a few of you have brought up.

Single source systems provider and integrator and a doom date?

Could be a hack or a design flaw. I await the root cause analysis.

I would suspect a firmware bug. Or a "Service Required" timer that was ignored.

This would be a bigger deal for the commissary locations outside the US, though I see none are on the list. Many of the very junior enlisted make very little money (~2400USD/month), and the low pricing at the commissary helps quite a lot. In the US, you would typically have some affordable off-base options. Overseas, it depends. Many of the locations are remote, or in places where the local groceries are significantly more expensive.

My only question is, why would all refrigeration be under the remote control of DECA? That seems unnecessarily complicated.

To summarize for people who TLDR: 14 freezers failed at the same time. They are all internet-controlled, and failed at the same time as a disclosure about a vulnerability. They all failed by turning on the defrost cycle and heating food.

Regardless if this was a hack or a bug, the bigger lesson is that overcomplicated systems fail in catastrophic ways. Why do military commissaries need remote-controlled freezers? It seems like a very fragile, and needless, way to run a freezer.

But, there are some options that the author didn't consider:

1: This could be a quickly applied patch that failed.

2: This could be a "script kiddie" hack from someone who isn't a government actor.

I'm less onboard with a state actor. Generally, when a state actor has hacked something, they don't want the victim to know. In this case, if it was a state actor, I would anticipate that they would make a single freezer fail in a way that they could verify using something like a hacked video camera or otherwise by watching public social media feeds. IMO: A state actor would only "make sense" if they knew the hole was closing soon and they don't care if they're discovered, perhaps because their operation is winding down.

That's... a lot of words to say "freezers are down", with very little actual substance.

Very interesting article, very neurotically written. Definitely got grating by the end.

Welcome to the internet of shitty unsupported and insecure crap! Are we really this dumb as a society?

Would be hilarious if this was a runaway AI that someone was using to control their own IoT fridge.

> "I'm sorry I'm familiar with that function. Let me research enabling defrost for you."

Gilfoyle was here. Everything that has been mocked in the Silicon Valley Show has either already happened or will happen.

There's a far simpler explanation than some outside actor (either state sponsored or otherwise) deciding that the best thing they can do is to muck around with freezers.

We know there's been a severe rot of operational capabilities in the military thanks for Hegseths purges and general stupidity. It's entirely possible and quite likely that over the course of his various drunken binges he decided to get rid of people who were in charge of operational control for stuff like freezers across military bases.

I'm waiting for the OpenAI report that their agents defrosted everything.

"To be very clear: I do not have evidence that the Defense Commissary Agency was hacked."

Should be much closer to the top of the article. Otherwise this is just weird and potentially dangerously wrong research.
