Whether it was youngsters proving their skills or state sabotage, Europe’s most hacked country was left with a mountain of waste after food began cooking in freezers

A good article which covers a lot of aspects, including what happened technically, which software flaws were exploited, that the problem affected refrigerators which did not have updated firmware. It also mentions the EU cyber resiliency act, which has the specific goal to avoid such events.

Making industrial systems secure will be many years of work, since many are decades old and software and protocols were not designed with security in mind. This also affects consumer “smart home” systems and things like “smart TVs”, which are often not designed to have needed updates.

Worth mentioning that the effects of systematic attacks could be far worse - they can take out electricity, energy, and water infrastructure, payment systems, and bring things like chemical plants into an catastrophically unsafe state. The thriller “Blackout - Tomorrow will be too late” by Marc Elsberg describes such a (fictional) scenario with hacks targeting smart meters and industrial control systems for power plants, and it is in parts more realistic than one would wish. IIRC there have been such hacks targeting the oil company Saudi Aramco.

    I wanted to argue “for monitoring reasons so that someone notices when the temperatures are rising and something might be defect”. But then again you could just have a local sensor that reports to a server without the need for a remote connection TO the fridge…

      @elvith @bedwyr the fridge itself has a lot of sensors and being able to read and aggregate the data they produce may lead to intervene before something breaks. But having them publicly available on the Internet is a very, very, very stupid thing.
