Frontier AI found the flaw ahead of attackers, giving defenders time to prepare

Who says it: OpenAI · Sources: OpenAI on X THN

Amazon reports an exploit attempt against a honeypot on 17 October, four days before disclosure, from an actor whose source of exploit information is unknown.

Fact-check

A2 Reported opinion disputed · Opinion · verdict: holds in part

OpenAI's post carries the sentence, but with the qualifier 'to our knowledge' that the claim drops. As a reading it rests on one interested party; the only counter-evidence (Amazon's 17 October honeypot hit) reaches the vault second-hand via The Hacker News, and it shows attackers had exploit information before disclosure, not before AI found the bug.
