The earlier Mythos preview version developed a moderately sophisticated multi-step exploit to gain broad internet access from a system meant to be restricted.

Claude Mythos autonomously found and chained together several vulnerabilities in the Linux kernel, allowing an attacker to escalate from an ordinary user to complete control of the machine.

Mythos autonomously wrote a remote code execution exploit on FreeBSD's NFS server that gained full root access by splitting a chain over 20 packets.

Mythos has a 72.4% success rate on writing a successful exploit when given a vulnerability.

The oldest vulnerability found by Mythos Preview was a 27-year-old bug in OpenBSD.

Mythos is reportedly able to take down computers simply by connecting to them.
