David Duggan, a resident of the east coast of the United States, experienced unauthorized charges on his credit card amounting to $400 for gift cards associated with his subscription to the Claude AI chatbot. After noticing these charges, Duggan contacted Anthropic, the company behind Claude, only to find that he was not alone in this experience. Other users on the online platform Reddit reported similar fraudulent transactions, with some facing multiple unauthorized payments. In response to these incidents, Anthropic has announced that it is implementing new security measures to prevent fraudulent gift card purchases. The company urges users to report any unrecognized payments and assures that refunds will be issued for unauthorized charges. Additionally, users are advised to cancel affected bank cards and change their login details to enhance security. This incident highlights the growing concern over the safety of online transactions linked to AI tools.
