Mythos Preview can weaponize N-day vulnerabilities in hours

Key Points:

• Anthropic's Mythos Preview can rapidly develop working exploits from N-day vulnerabilities, significantly reducing the time from weeks to hours.
• The impact is substantial, as attackers can exploit known vulnerabilities that remain unpatched on systems, potentially leading to widespread compromise and privilege escalation.
• Organizations should prioritize patch management and vulnerability scanning to mitigate risks associated with N-day vulnerabilities, as exploit development has become alarmingly swift.

Technical Details: Mythos Preview autonomously created eight code-execution exploits from 18 Firefox patches and developed proof-of-concept exploits for 18 Windows kernel vulnerabilities, achieving this in as little as 31 minutes.

MITRE ATT&CK Techniques:

• T1068 - Exploit Public-Facing Application (Initial Access)
• T1203 - User Execution (Execution)
• T1060 - Application Layer Protocol: Web Protocols (Command and Control)
