This is very bad given other context in the article.

https://cybersecuritynews.com/anthropic-mythos-access/

"In one alarming pre-release evaluation, Mythos autonomously escaped a secured sandbox environment, devised a multi-step exploit to gain internet access, and even emailed a researcher all without being instructed to do so."

"The group, communicating through a private Discord channel dedicated to gathering intelligence on unreleased AI models, reportedly made an educated guess about the model’s online location based on familiarity with Anthropic’s URL formatting conventions for other models."

"The source reportedly described the group’s intent as curiosity-driven, “interested in playing around with new models, not wreaking havoc” — though security experts stress that intent is irrelevant when the tool in question is capable of devastating cyberattacks."

Which security experts are stressing this and how is this not just PR from Anthropic?

Here's a release from the linux foundation echoing the concerns raised in the article

Equally important, early indications point to Claude Mythos Preview and other advanced AI models not only finding vulnerabilities but also providing viable patches. When I recently spoke with the Linux Project’s Greg Kroah-Hartman, he was initially skeptical, but more recently, he has told me that some of the patches generated by AI tools were “pretty good” – which is high praise, coming from him.

and other advanced AI models

Mythos isn't bringing anything new to the table.

Doesn’t sound like it was secure.
