    Fabian Wosar Retweeted CD PROJEKT RED

    The amount of people that are thinking this was done by a disgruntled gamer is laughable. Judging by the ransom note that was shared, this was done by a ransomware group we track as "HelloKitty". This has nothing to do with disgruntled gamers and is just your average ransomware.https://twitter.com/CDPROJEKTRED/status/1359048125403590660 …

        Before CDPR the same group has hacked the Brazillian energy company CEMIG late last year. Earliest victims date back to November 2020, way before CyberPunk was even released. I can see the appeal of the "this was revenge by a former fan", but life is much more boring than that.

        Fabian, those ransomware have a very high level of detections at virus total. Why did it pass? Is this is a special version made exactly for this attack?

        Once you obtained admin credentials for the network, you just disable the AV before detonating your ransomware. That's what TAs do. There is no reason to hide your ransomware.

        Extraordinary claims require extraordinary evidence, this applies to any & all attempts at attribution. Writing analysis comparing cdpr note to known hellokitty notes shows differences (https://www.cadosecurity.com/post/punk-kitty-ransom-analysing-hellokitty-ransomware-attacks …). Are you able to share IoCs / attribution indicators you're using?

        As this could be true...it’s still very true/possible that a hacker can be a gamer and vic versa, let alone a disgruntled gamer wanting to strike back by hacking. Since release of Cyber Punk 2077, it’s been in the bad news bin. Haven’t heard much different & it’s alrdy Feb. 2021.

        There most likely isn't a single person on the planet who hasn't enjoyed playing games at least once. But the reason they hit CDPR has nothing to do with games and all to do with money. I could also say "water drinkers targetted CDPR" which is just as true and equally irrelevant.

        Total ignorant here : Who could buy such a thing ? To what interest ? From my pov, concurrent companies would not take the risk of having such files in their data as it's illegal. So some rich guy(s) willing to sell all this bits by bits ?
