US artificial intelligence (AI) company Anthropic says its technology has been "weaponised" by hackers to carry out sophisticated cyber attacks.
Anthropic, which makes the chatbot Claude, says its tools were used by hackers "to commit large-scale theft and extortion of personal data".
The firm said its AI was used to help write code which carried out cyber-attacks, while in another case, North Korean scammers used Claude to fraudulently get remote jobs at top US companies.
Anthropic says it was able to disrupt the threat actors and has reported the cases to the authorities along with improving its detection tools.
