Two new research papers highlight vulnerabilities in current defenses against AI model extraction attacks. One paper proposes a simple yet effective detector that analyzes traffic window distributions to identify deviations from normal API usage, achieving high detection rates with low false positives. The second paper demonstrates that existing defenses, which often assume single-client attacks, can be bypassed by coordinated, multi-client strategies, rendering them ineffective against sophisticated adversaries.
