Iran-linked Cyberattackers Shut Down a UK Power Plant for Four Days (bbc.co.uk) 37

"Iran shut down a British power plant for four days in an unprecedented cyber attack," reports the Telegraph.

More details from the BBC: The government said that at no point was there a risk to the UK's energy system, but the Department for Energy Security and Net Zero (DESNZ) has contacted power companies to advise them about the risk of cyber attacks... DESNZ said the incident had affected a small-scale generator and at no point had there been a risk to the wider energy system. The UK's power network has a number of smaller gas generators which provide short-term power when needed.
Thanks to Alain Williams (Slashdot reader #2,972) for sharing the news.

    "at no point was there a risk to the UK's energy system" - what other than a plant being taken offline by a "hostile nation". No risk at all...

    This seems to be propaganda : There's absolutely no independent source, this seems to originate from some gossip by an official in UK's government, sourcing it to the NCSC (a branch of GCHQ), who in turn declined to comment.
    The Telegraph heavily uses "it is understood that..." which hints that they were giving very vague information that they're in no way able to confirm.
    Also, about Slashdot's summary: there's no more details from the BBC, they're basically pointing to The Telegraph's article.

    • The BBC directly attributes some information to the Department for Energy Security and Net Zero (DESNZ), which indicates they may have been able to confirm some of it.

      Iran-linked hackers behind cyber attack that shut down power plant, reports say

      A small power plant in the UK was shut down during a cyber attack.

      Most press accounts follow this same pattern. You never know who the source is and you have to trust the press is not full of shit. The quote from the government source seems to imply more than gossip as they are seemingly aware of what plants were impacted:

      "A government source said: 'We have thresholds for important generators to legally notify us of cyber activity, and this site is nowhere near. Itâ(TM)s a very small-scale site, less than a rounding error compared to grid capacity.' "

    • Especially since it's not clear what's in it for Iran. They're not at war with UK, but they are at war with US, so wouldn't a US power plant make a lot more sense as a target? Afaik during the course of this war so far Iran has only attacked targets belonging to either US and Israel or to the neighbouring Gulf nations. OTOH this government has been known to use foreign policy as a distraction to domestic problems, as have a lot of governments. Add to this that The Telegraph is known to, let's just say, not

        They hit what they can. Iran has attacked or threatened many countries, including the UK [bbc.com].

        It's understandable. If I were the head of the Islamist regime in Iran, I would be trying to build up nuclear weapons that could hit America as quickly as possible.

        • But this isn't about a missile attack. A power plant in US should be just as easy to hack as a power plant in UK. I bet some idiot pressed a wrong button or something or they deployed cool new software which hasn't been tested very much, and then they decided to blame this on the Iran boogeyman instead.

          • The question was what motivation Iran would have to attack a power plant in the UK. And there is the answer.

            As for the rest of your post, I agree, it doesn't seem likely this was a hacking attempt, and attribution evidence is missing.
    • We deserve better psyops.

      If the reporter had read Chomsky's Manufacturing Consent they could have done a better job but let's not give them any ideas.

      BBC has always been in the business of narrative construction in service of the powerful to control the population.

      And also Benny Hill.

    • It is always propaganda but usually inspired by real events. In this case even that is not sure.

    Good, it will help reveal exploits sooner rather than later. Better now than in a more serious conflict involving Russia or China.

    • by dbialac ( 320955 )
      The exploit is having a power plant or other critical infrastructure connected to the internet, period. Not through a VPN, not through anything.
      • I can't wrap my head around how or why that could still happen, let alone that it does. Why the hell would they expose anything to the internet? They don't need any internet connectivity, not even through a VPN.

          Probably, a senior executive wanted a dashboard widget that showed real time status — or something like that.

  • "unprecedented cyber attack" - yeah right, pretty run of the mill today given the lack of guardrails installed.

  • Israeli linked.

    Wanting total internet connectivity is a sign of utter ignorance, and that ignorance is a choice.

    Make ignorance shameful again.

    • Oh man you would eat your words if you ever worked in the power generation industry. Protip: We don't run the electrical grid like we did in the early 90s anymore. The grid functions now largely because the entire system is networked together and because engineers have instant oversight. If you want more power outages that last far longer than today, then sure, take things offline. Just don't be the one who complains that when a local breaker trips or a local generator is offline that you're sitting in the
