Anthropic just published its most detailed report yet on how people are trying to misuse Claude, and it does not read like a routine safety update.
Between December 2025 and August 2026, the company’s threat intelligence team tracked and shut down attacks across seven different categories: cyberattacks, influence campaigns, surveillance, scams, weapons research, and more. Some of it sounds like it belongs in a thriller. A Russian espionage group ran automated intrusions against more than 20 organizations using Claude to help. Attackers built AI-orchestrated hacking campaigns where the model was not just assisting a human, it was running the operation from reconnaissance through to stealing the data.
The part that stopped me was the bioweapons line. Anthropic said, for the first time from a major AI lab, that its newer models can no longer be assumed to sit safely below the threshold for meaningful bioweapons assistance. That is a big sentence to put in writing. It also means the company is choosing to say it out loud instead of quietly hoping nobody asks the question in public.
There is a business side to this too. Anthropic says Alibaba ran the largest model distillation campaign it has ever measured, pulling nearly 3 million exchanges a day from thousands of fake accounts to train its own Qwen models on Claude’s reasoning.
Here is the part I keep coming back to. Every single operation named in this report got caught and shut down before it did lasting damage. That is not nothing. The same reasoning ability that makes these models dangerous in the wrong hands is what let Anthropic’s own systems spot the pattern and pull the plug. Guardrails are getting tested for real now, out in the open, not in a lab. So far they are holding up.
