  The freshest Akira variant uses old-timey encryption method vulnerable to brute-force methods

  It breaks old-timey encryption.

    It’s nice to know that 4090s won’t break new timey encryption in that amount of time.

  In other news ZFS and proper back ups do this in about 30 seconds.

    I know you meant backups can protect against ransomware, but it would be pretty funny if ZFS included a ransomware password cracker

      Depending on the depth of the ransomware a simple “zfs rollback” will fix all your problems.

  Does this mean that 1 RTX4090 can do it in a week?:)

  Not sure if they have this specific GPU or not, but I know AWS has on-demand instances with GPUs (and other cloud providers like Google likely do as well). It’s probably just a matter of time before somebody deploys self-service images so a business that got hit by this ransomware could quickly recover on their own.

  So stick to wibbly wobbly, timey wimey encryption? Got it.
