Researchers have investigated the effectiveness of query monitoring as a defense against distributed model extraction attacks on AI models. Their study, utilizing one million real chat turns, found that distinguishing malicious extraction campaigns from normal user activity is challenging, especially when network and payment metadata are unavailable. The effectiveness of detection depends on the campaign's distinctiveness compared to regular user behavior, with slow-ramping campaigns potentially poisoning monitoring systems. While some monitoring techniques showed promise in detecting naive attacks, others failed to identify campaigns that mimicked real user requests or operated at low colluder shares. AI
