Article summary
Quick briefing — cleaned from the original RSS feed
Claude Mythos found HAWK and reduced-round AES weaknesses in 60 hours for ~$100K, producing the CryptanalysisBench benchmark. Anthropic's Claude Mythos Preview discovered mathematical flaws in both HAWK, a post-quantum signature scheme, and a weaker version of AES in 60 hours of continuous operation. The experiment cost roughly $100,000 in API fees and produced results that human experts had reviewed for over two years without finding, according to Anthropic's research blog published July 28,…
