Anthropic claims Alibaba led a massive AI distillation effort to steal capabilities

Anthropic says Alibaba and its affiliates executed a large-scale distillation attack against its Claude models, using about 28.8 million model exchanges with roughly 25,000 fraudulent accounts between April 22 and June 5 to extract AI capabilities. The company described the activity as the largest distillation campaign to date and urged coordinated action from government and industry to curb illicit AI distillation, noting ongoing regulatory scrutiny and export-control actions affecting its models. Alibaba has not commented.
