@GossiTheDog First thing I thought when I heard about this was “Advanced Persistent Teenagers at it again!”
It’s a teenager kind of attack. A target no adult would think about because adults have forgotten all of the open targets that we’ve been safely (de facto) been ignoring forever. -

@GossiTheDog Chances of customers updating the firmware in the last few months.
vs Chances they will update it now? -
I’ve seen some breathless reporting in the media about the situation in France saying it’s the biggest cyber attack ever and the result of a swarm of Agentic AI bots.
Reality: no. It’s a complete lack of security controls and negligent product development by the vendor.
@GossiTheDog It's like the excuse of all excuses. Remember APTs back in the early 2000s (maybe it was the early 2010s), and everybody got so sick of that term because that's what everybody would say: "Oh, we were breached. It must have been an APT." No, your security just sucks. Now it's, "Oh, we've been breached. It was an agentic storm of rogue AI." No, your security just sucks.

The username is admin and the password changes every day automatically to.. the current date.
Every single one is like this. You can just log in and change the temperature. Anybody can do it, easily scriptable.
@GossiTheDog You could store random data in an array of these across the world by setting the temperature & then watching the current temperatures fluctuate around those & use it as a source of entropy. Obviously only use three or four time zones that are in the middle of the day at a time.
New worst way to generate key pairs?

@GossiTheDog Wait till someone tells them boilers use the same system.
Oh noooossss security something something...

LinkedIn’s absolutely awash with security vendors posting brain-dead takes on the fridge thing as they have no idea, at all, what they’re talking about. It’s great as it’s a list of people not to hire.
You may be surprised to know the through line to the posts is.. AI. Remember when we had intelligence.
@GossiTheDog I don't see the brain-dead takes from people I shouldn't hire. Can you share?

@GossiTheDog I'm not a security professional but... sounds like the kind of thing that should live on an isolated network?

@GossiTheDog a cookie to the genius that had this idea xD

@GossiTheDog Sometimes a teen wonders what if they did decide to connect to one of the random unprotected industrial controls they see on @vncresolver, what sort of trouble could be caused.

@GossiTheDog "System Manager AK-SM 800A software package v4.0x and above enhances your product's security features to meet internationally recognized regulations. Danfoss is now defaulting to a strong security posture and is following secure by design principles."
Snark aside, the list of security features they tout as being available with the new v4 in 'strict' mode is rather terrifying.
@fuzzyfuzzyfungus @GossiTheDog So.. with strict mode disabled (which was default until a certain version), they allow HTTP connections, use plaintext authentication, and don't sanitise inputs.
And they admit this..

Why are those on the internet or connected to thr network anyway? I mean yes, you could query its temperature and run a monitoring system that alerts you when one of the fridges becomes too warm due to a malfunction. But for that readonly access is enough. Why is the temperature remote writeable?? And what else can be done with the access? Only temperature? What is the regular usecase here? -

Yeah, well the difference to "throw-away agents" is smaller than one might think these days. And the simultaneous "IT issue" in NL is ... an interesting coincidence.

Do you know what Danfoss also produces: home thermostat applications. Incl. ones that are app-controlled, so internet-facing. Hmm.

@GossiTheDog And some sandwiches went to waste. Judging from the symptoms as described in the press they had their fridges connected to the open internet.
Everything that really matters is minimised in public discourse, sidelined, or made look negligible.
All the things caused by negligence, bad decisionmaking, and terrible ideas get a free pass.

@GossiTheDog and who in their right mind doesn't design a hard maximum temperature for a fridge thermostat of something resembling room temperature?
-
You can literally recreate it with a single line bash command to apply to the internet in a loop. A write-up on how to defrost the fridges appeared online in August. It’s a zero-skill thing to pull off, I wrote the bash script while having a shit.
