TOKYO – A 25-year-old man has been served a fresh arrest warrant for allegedly creating a computer virus using generative artificial intelligence (AI), the Metropolitan Police Department (MPD)'s cybercrime control division announced on May 28, in what is believed to be the first such case in Japan.

Ryuki Hayashi, an unemployed resident of the Kanagawa Prefecture city of Kawasaki, was served the warrant on suspicion of making electronic or magnetic records containing unauthorized commands.

Hayashi is accused of creating a virus similar to ransomware, which destroys computer data and demands ransom in cryptocurrency, using his home computer and smartphone on March 31, 2023. He has reportedly admitted to the allegations, telling police, “I thought I could do anything by asking AI. I wanted to make easy money.”

    Computer virus. Okay. Phew.

    Though a computer virus could someday be just as deadly as a regular virus.

        Even now, deaths can be attributed to hospitals profiting off completely insecure systems.

          What freaked me out were the IV drug dispensers that dialed into wifi for app control (and yes, they’re less secure than your roomba).

          It’d make a great fictional assassination story if one was commandeered to kill a VIP by morphene or insulin overdose. No such incident has occured yet IRL. But I’m sure it’s worth like 20 cyberpunk dystopia points when it does.

          You are correct, but I hope we can all agree there is a special place in hell reserved for people who interfere with health workers and cause death in the process.

          That’s right on par with raping a nun, or a priest diddling a kid in my book.

          That’s a bit of victim blaming. Yes, everyone can take steps to be more secure, but don’t blame them for getting hacked.

            That’s true, I agree with this sentiment. But I’m a bit confused when trying to apply the same logic to credit bureaus and other companies which get hacked and expose our personal information without facing any real consequences. In those situations I feel that those companies should be held liable for the breaches.

    Apparently the warrant was served only after an discovering evidence from an unrelated (or semi-related?) arrest? The article didn’t specify if his ransomware worked, but I doubt it did if it was mostly GPT-generated. I guess the intention and confession is enough to make charges stick though. Wouldn’t be surprised if whatever GPT service he used also flagged him as suspicious and led authorities to him.

      Japan has a suspiciously high conviction rate though (>99%). They either don’t even go for criminals they are not sure about or there’s some form of tampering going on. Hard to say.

        The conviction rate is 99.3%. By only stating this high conviction rate it is often misunderstood as too high—however, this high conviction rate drops significantly when accounting for the fact that Japanese prosecutors drop roughly half the cases they are given. If measured in the same way, the United States’ federal conviction rate would be 99.8%.[14][15][16]

        From wikipedia.

          Comparing Japan to a prison colony makes it look a little more reasonable.

            I don’t agree with most western philosophies of prison, the US is probably the worst amongst them (but most of that comes at the state level), I was just highlighting that Japan isn’t in some way uniquely bad for ‘western’ law systems. Indeed, conviction rate is a really hard stat to do any sort of apples to apples comparison for because different countries count and report it different ways.

        Apparently it’s the former. Their prosecution rate is 8% apparently according to Wikipedia, because they’re too understaffed to deal with cases that can go either way. They also have a false confession problem, but that’s not what’s getting them to that rate.
