Ars technica's article is not as optimistic: > Had the researchers performed their attack on Amazon's Web Services platform, it would have cost $560,000 at normal pricing. Had the researchers been patient and waited to run their attack during off-peak hours, the same collision would have cost $110,000. That's within the $75,000 to $120,000 range CWI's Stevens projected in late 2015. Not cheap but definitely achievable by a wealthy individual or corporation.
