Quite the double standard here...

  Conventional Weapons

  -We identified a cell of threat actors based in northern Yemen
  -We identified a China-based threat actor who used Claude 
  -We identified likely freelance Russia-based threat actors
  -We identified a China-based actor who used Claude’s chat
  -In this case, a Russia-based actor used Claude
  -We identified a China-based threat actor who used Claude 

  Biological misuse

  We are withholding the names of research institutions, the   countries wherein the activity took place, and the specific biological agents or research techniques involved. The individuals implicated in these case studies are working scientists. We do not assert that they intended harm, and identifying them or their labs could expose them to harm.

Anthropic:

- We identified someone building a death star with Claude

- We identified someone building a wormhole with Claude

- We identified someone building a blackhole with Claude

- We identified someone building a quantum drive with Claude

We are withholding all evidence though, sorry. Just trust us, it's really bad out there and Claude is really powerful.

For all we know, the boxes connecting to Claude from Yemen, Russia, and China could have been ORBs of actors from entirely different states. Attribution is non-trivial

How is this a double standard?

A cell of actors in northern Yemen building guided rockets was not working on a PhD dissertation. You are allowed to use common sense sometimes.
