Anthropic has reported to the US Senate that Alibaba Group engaged in a large-scale "distillation attack" over six weeks, using 25,000 fake accounts and 28.8 million conversations to copy Claude's reasoning and coding abilities. This data was then used to train Alibaba's Qwen model. Anthropic has characterized this as the largest such attack in its history and is advocating for new legislation, as the activity is not clearly illegal under current laws. AI
