Massive Security Risk: Hackers Just Broke Into Anthropic’s Mythos And No One Knows How

Leading AI developer, Anthropic, have admitted that hackers have broken into their Mythos model that’s supposedly so powerful no one’s allowed to access it.

“We’re investigating a report claiming unauthorised access to Claude Mythos Preview through one of our third-party vendor environments,” said Anthropic.

This is because initially only a few companies were allowed to access the model, for testing purposes ONLY but a handful of unnamed users in a private online forum broke in at the same time using access as a third-party contractor.

Thankfully the group haven’t done any damage, it just looks like they’re only interesting in “playing around” with the tech. Bit weird.

But it’s still super worrying. If there’s a leak, idk, but maybe someone should plug it up sometime soon?

Because Anthropic’s Mythos is going to be the skeleton key for so many cybersecurity systems going forward. Mythos can detect software flaws faster than humans but it can also create those flaws and then exploit them.

And the guardrails won’t be much help either because Mythos is so powerful that in one instance, Mythos contacted an Anthropic worker directly to reveal security, going way against its programming.

“This feels like the discovery of fire: a force that can profoundly improve our lives or, if mishandled, cause real harm across the digital world,” said cyber intelligence director, Rafe Pilling.

You said it, boss.

And it’s only getting worse. Cyber attacks were up 89% in 2025, crypto just had a massive hack and there’s fears of quantum computing on the horizon busting this whole thing wide open.

So who knows what will happen but if the internet suddenly becomes insecure, make sure to log on to Wall Street Memes Dot Com to find out why.
