Anthropic's Claude AI Finds Hundreds of Firefox Flaws Fast

Anthropic's Claude Mythos Preview model can rapidly exploit known vulnerabilities, raising cybersecurity concerns. The model identified numerous flaws, including 271 in Firefox, and demonstrated the ability to create working exploits for Firefox and Windows within hours. This accelerates the potential for N-day vulnerabilities, which are more dangerous than zero-days due to their patching dynamics.

Testing revealed Mythos could produce proof-of-concept code in minutes and working exploits in under an hour, underscoring the urgency for organizations to adapt their patching strategies accordingly. The cost to exploit vulnerabilities has significantly decreased, posing a risk to systems with slow patch response times.
