How easy is it in 2022 to find a SHA1 collision?

You can also just rent three p3.16xlarge AWS instance with a hash rate of ~135GH/s each at a cost of ~$24.48 per instance per hour, for a total of 405GH/s for $73.44 per hour. That would take you ~2397.12 hours (3 months) and cost you ~$176,044.

Remarkably, we can see that in only 5 years, we're down from an attack costing ~110 GPU years to an attack costing ~8 GPU-years in 2020 (thanks to theoretical improvements & newer GPUs) to just ~5.4 GPU years nowadays (thanks to newer, faster GPUs).
