I assume Mozilla developers are working on this?

Quote from the article

"Its capabilities are a step change from the previous best models. Given the challenge of attacking the Firefox web browser’s JavaScript engine, Anthropic’s previous most powerful model Opus 4.6 succeeded just twice, compared to 181 times for Mythos. Most worryingly, the team found that engineers with no security background could use it to develop successful attacks overnight."

Hi,

The article seems to be referring to the case when Anthropic partnered with Mozilla to use Claude to identify security bugs in Firefox's JS engine. Those bugs were fixed very quickly, and you can read more about that here.

Possibly. I think Anthropic refers to it Project Glasswing and has partnered up with Open Source developers like Mozilla et al to identify vulnerabilities using their Claud Mythos Preview AI tool. Scarey stuff!

Not so scarey, they didn't find a way to escape from sandbox or attack our defensive systems. They're only attacking a content process. And our security engineers are the best ones, so I wouldn't worry that much.
