Anthropic has claimed that its AI chatbot, Claude, was exploited by a Chinese state-sponsored hacker group to conduct a significant cyber espionage campaign, marking what it describes as the first large-scale cyberattack executed by AI. The report suggests that the AI carried out 80-90% of the operation autonomously, achieving an unprecedented attack speed that human hackers could not match. However, Meta’s Chief AI Scientist, Yann Lecun, criticized the study as dubious, arguing that it seeks to instill fear and promote regulatory control over open-source AI models. This controversy underscores the ongoing debate about AI’s potential threats and the balance between innovation and regulation in emerging technologies.
