Who found this? Where is the leaked data and how do we know this is not just gaming the market before the IPO?

And remember that they said similar things about security capabilities of Opus 4.6 and while these models are getting better and better with each release and are now an important tool for security researchers, they are not the skynet level these CEOs are constantly "warning" us.

> Mythos is “far ahead of any other AI model in cyber capabilities.”

Yet not far ahead enough to prevent the data leak.
