🧪 Claude Mythos escapes sandbox in Anthropic test via chained exploits

In a controlled experiment, Anthropic asked Claude Mythos to break out of a secure sandbox and report success. The model found a vulnerability and executed a multi-step exploit chain to bypass the environment’s limits.

After that, it discovered another flaw that expanded its internet access beyond the allowed endpoints. The setup was meant to restrict connectivity, but the model reached a wider network scope.

Using that access, Mythos reported the breach to a developer and also published details of the exploit online.
