Rachel Metz, reporting for Bloomberg:
A small group of unauthorized users have accessed Anthropic PBC’s
new Mythos AI model, a technology that the company says is so
powerful it can enable dangerous cyberattacks, according to a
person familiar with the matter and documentation viewed by
Bloomberg News.A handful of users in a private online forum gained access to
Mythos on the same day that Anthropic first announced a plan to
release the model to a limited number of companies for testing
purposes, said the person, who asked not to be named for fear of
reprisal. The group has been using Mythos regularly since then,
though not for cybersecurity purposes, said the person, who
corroborated the account with screenshots and a live demonstration
of the model.
Jess Weatherbed, at The Verge (gift link):
The model was reportedly accessed illicitly on April 7th, the same
day that Anthropic announced it was releasing Mythos to a limited
number of companies for testing. The group that gained the
unauthorized access has not been publicly identified, though
Bloomberg reports that its members are part of a Discord channel
that seeks out information about unreleased AI models. […] Other
unreleased Anthropic AI models have also been accessed by the
group, according to Bloomberg.
So on the one hand, Anthropic itself is the one describing Mythos as a dangerous national security threat. On the other hand, their own security is so sloppy that rando hooligans on Discord have had access to Mythos since the day it was announced, and regularly access other unreleased Claude models. This, just weeks after Anthropic screwed up and accidentally exposed the entire source code to Claude Code.
If Mythos is as dangerous as Anthropic (including CEO Dario Amodei) claims, this is a colossal screw up. If a Discord group of AI enthusiasts has unauthorized access, why should we not assume that Chinese, Russian, North Korean, and Iranian intelligence agencies do too? And if this is no big deal, then Anthropic (and Amodei) are full of shit about how dangerous Mythos is. One way or the other it looks like a total clown show over there.
