(Specifically, Anthropic claimed that the attack was carried out by Chinese state-backed hackers, which is a whole can of worms. You can read their internal report here: https://www.anthropic.com/news/disrupting-AI-espionage)

It did seem a bit “big” to me in the internal report because they kind of exactly explain how the attack was carried out and how you could do the same, if you’re technically-savvy enough.
