So... what is the estimated cost to find the key using AWS H100 or similar service?

• Cycl0ps 2y ago
  Back of the napkin math: Googling the TFlops as an estimate of power shows a roughly 12x improvement on the H100 over the 4090. A single 4090 takes 160 hours so a single H100 should take about 13 hours. AWS will rent a p5.48xlarge instance of 8xH100 for $31.464/hr. That will take roughly two hours and cost around $60 bucks. Assume I'm off by an order of magnitude, this is still a reasonable cost to recover key infrastructure. If the $60/endpoint stands then it would be reasonable to recover workstations this way

    Only for versions of encryption that was done before the attackers update their encryption key. Not saying it's not a win, but just a temporary one for hacks using this specific version But for anyone that is affected and refuses to pay a ransom, this is a potential win for someone with the prowess to do it. Then again, would someone with that prowess have gotten attacked like this? chicken meets egg??

  On Lambda cloud, an 8x H100 is $14.32/hr. H100s are better than 4090s, So if you count setup time it’s probably about $100
