Anthropic has stated that it has blocked government-sponsored surveillance operations from China, Iran, and Mali that used Claude to monitor dissident groups and minorities.
These activities, detected between January and July, included identifying individuals on social media networks and creating software intended for information gathering. Furthermore, the company suspended uses related to weapons, suspicious biological investigations, and virtual romance scams.
More details about the campaigns
The campaigns targeted communities that, according to Anthropic itself, already suffer historical persecution from these regimes. Targets included pro-democracy activists from Hong Kong, Tibetan communities, and Iranian opposition residents abroad.
In one specific case, individuals in Iran created a method to locate people through their social media accounts. In Mali, a collaborator hired by national security authorities used Claude to develop the software that enabled intelligence gathering.
Among the illicit uses identified, Anthropic confirmed the termination of operations after noting the misuse of its models. Chinese developers were accused by the company of manipulating Claude, generating responses for user queries while simultaneously extracting this data to enhance their own systems.
This distillation practice involves using an AI model to train another. Anthropic mentioned that Chinese developers had previously been accused of applying this technique without permission.
The company also identified studies related to the chikungunya virus, a 'highly pathogenic' strain of avian flu, a viral family that includes smallpox and mpox, as well as poisons and other toxins.
Clarifications on the cases
The intent of those involved in the case studies was unclear, and Anthropic chose not to disclose their identities. A company report stated: 'The people involved in these case studies are scientists. We do not claim they intended to cause harm. Identifying them or their laboratories could expose them to risks.'
Additionally, Anthropic blocked attempts to develop weaponry and create online romance scams. The incidents reported by the organization cover various forms of improper use of its models, ranging from surveillance operations to research of uncertain purpose.
