Chains in Sweden, Belgium and Luxembourg say fridge temperatures rose overnight, similar to hack of French stores

Supermarket chains in Sweden, Belgium and Luxembourg have said the temperatures of their refrigerators and freezers in dozens of stores rose overnight, prompting fears of a cyber-attack similar to one that caused millions of euros of food losses in France.

Sweden’s Coop chain told the daily Aftonbladet on Monday that six of ​its stores ‌had been ​affected, while ICA said it was “aware that a limited ​number of stores were affected by an incident overnight which impacted their refrigeration and freezer systems”.

Man the person who starts making appliances that don't connect to the Internet is going to make bank

Seems like my ability to break chips is now marketable!

Once it could be anything, a test or some random asshole doing stuff. twice its starting to look like pattern. If it happens 3 times then its a pattern most definitely. Though the attacker could have targeted absolutely everything at the same time in the first place, so it could be more aggressive pointing out that critical things(parts of food suppily storage) are not secure at all. So it doesnt seem malicious.

It could be a copycat or even just a bored kid seeing what they can do. If the first attack was successful but none of the rest of the vulnerable systems were patched, further attacks are inevitable. The pattern is just that known exploits will be exploited given enough time and bad actors.

some random asshole doing stuff

I don't have the reference anymore, but there was an article explaining that all those freezers were on the internet and it was the easiest thing to crack ever, like one simple command-line to execute to wreck everything.

The fact that supermarkets all over the world didn't do anything proves how stupid and reckless they are.

Why the fuck are they connected to the Internet?

[–] mjr@infosec.pub 2 points 1 day ago (1 children)

Diagnostics and repair. The question is why they still have default passwords and no limits on what operations remote users can do or how often.

Refrigerators are not hard to diagnose or repair. The only reason to have them hooked to the Internet is to try and get out of paying someone to work on them. In that case I say; Good. Stop trying to take people out of the equation because stupid shit like this happens.

[–] mjr@infosec.pub 2 points 1 day ago (1 children)

I didn't say it was a good reason.

But would a worker spending time travelling to a customer site to do something they could have done from their desk be a good and rewarding job for them anyway?

[–] JustPlainDave@lemmy.zip 3 points 1 day ago (1 children)

They don't have a maintenance guy that works in store? Seems like a poor business plan.

Curious to hear from someone more knowledgeable about security if this seems like an economic attack by another country, or what? The only other motivation I can see here is to force supermarkets to be more secure without doing serious damage (serious like people starving).

It's most likely some script kiddie taking advantage of hilariously bad security practices. The attack three weeks ago was because the freezers were directly connected to the internet, running old vulnerable firmware with the username "admin" and the password always being the current date. This is probably going to end up being a similar case - might even literally be the same case, three weeks (and IIRC there's been an update fixing it for six months) is such a short time to unplug your vulnerable freezers from the internet, after well.
