It breaks old-timey encryption.

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

Good thing when my main rig goes down I have a, checks notes, 16 RTX 4090 BACKUP MACHINE.

In fairness if you really needed to you could rent this kind of compute via a service like vast.ai, it'd probably still be cheaper than paying a ransom.

Just build a new one, at the cost of....
Nevermind, pay the ransom.

You don't need a whole new system just another clean hard drive to boot from and use the 16x RTX 4090 to calculate the code. EZPZ.

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.
