Summary
That’s according to a detailed blog post from Katie Moussouris, the founder and CEO of Luta Security. It remains unclear exactly why Amazon decided to test the safeguards around Fable and when it first contacted Anthropic about the issue. Moussouris wrote that the jailbreak Amazon discovered was simple and involved giving Fable software code with known vulnerabilities. She wrote that the vulnerability that Amazon discovered “cannot meaningfully be fixed, and any attempt would only weaken the model for defense.” Many other AI models can also be used to spot security flaws in existing code. Mythos was the first model to successfully complete both cybersecurity “test ranges” that the U.K. AI Security Institute uses to test the hacking abilities of AI models.
The letter also notes that Anthropic had built multiple protections into Fable to prevent its use for cyberattacks. Axios cited an unnamed source familiar with the Trump administration’s thinking around the export controls as suggesting that Anthropic’s decision to engage Moussouris to review the Amazon research might have inflamed tensions with the White House and precipitated the export controls.
