I don't doubt of course that reports intended for government agencies or security experts would have those details, but I am not surprised that a "blog post" like this one is lacking details.
I just don't see how one goes from "this is lacking public evidence" to "this is likely a political stunt".
I guess I would also ask the skeptics (a bit tangentially, I admit), do you think what Anthropic suggested happened is in fact possible with AI tools? I mean are you denying that this is could even happen or just that Anthropic's specific account was fabricated or embellished?
Because if the whole scenario is plausible that should be enough to set off alarm bells somewhere.
1) Just a general assumption that all bad stuff from China must be state-sponsored because it’s generally a top-down govt-controlled society. This is not accurate and not really actionable for anyone in the U.S.
2) The attack produced evidence that aligns with signatures from “groups” that are already widely known / believed to be Chinese state sponsored, AKA APTs. In this case, disclosing the new evidence is fine since you’re comparing to, and hopefully adding to, signature data that is already public. It’s considered good manners to contribute to the public knowledge from which you benefited.
3) Actual intelligence work by government agencies like FBI, NSA, CIA, DIA, MI6, etc. is able to trace the connections within Chinese government channels. Obviously this is usually reserved for government statements of attribution and rarely shared with commercial companies.
Hopefully Anthropic is not using #1, and it’s unlikely they are benefiting from #3. So why not share details a la #2?
Of course it’s possible and plausible for people to be using Claude for attacks. But what good does saying that do? As the article says: defenders need actionable, technical attack information, not just a general sense of threat.
Now anthropic is new and I don't know how embedded they are with their hosts government compared to a FANG etc but I wouldn't discount some of #3
(If you see an American AI company requiring security clearance that gives a good indication of some level of state involvement. But it might also be just selling their software to a peaceful internal department...)
