Amazon.com (AMZN) and Alphabet-backed (GOOG, GOOGL) Anthropic said Thursday that its Claude AI models had been used by suspected state-sponsored actors, criminals, spyware vendors, state propaganda institutions and politically motivated individuals for malicious activities including fraud and surveillance of dissidents.

The malicious actors are continuously attempting to circumvent safeguards, the company said in a report detailing examples of abuse of its services.

"We'll continue to evolve our safeguards and coordinate with our partners to improve our ability to detect, disrupt, and prevent future misuse," the company said.

Among the uses cited was a Russian state-aligned foreign information manipulation and interference operation targeting the Central African Republic, the company said.
