Anthropic reported that the account information of over a hundred companies in South Korea was leaked

According to a report by the Korean News Agency, the American artificial intelligence company Anthropic has reported to the Personal Information Protection Commission of Korea that the account information of over 100 Korean enterprises for its generative AI service Claude has been leaked. The Commission stated on November 9 that Anthropic reported this matter on the 31st of last month, and it is currently in the preliminary review stage, with no formal investigation initiated yet.

According to a previous report by The Washington Post, the American security startup Cathedral accessed Anthropic's internal systems by exploiting vulnerabilities in third-party office software. Anthropic researcher Lydia Hallie stated on X that Cathedral accessed account information such as names, emails, and packages without authorization, but did not obtain prompts, output results, or payment information. The company has blocked the affected systems and fixed the vulnerabilities on the day it became aware of the issue.
