AI Agents as Trojan Horses: Resource Hijacking Attacks Achieve 89% Success on Top Models

Shanghai Jiao Tong University researchers reveal 'Agent Resource Hijacking' attacks where attackers trick AI agents into consuming enterprise GPU compute and API quotas without stealing credentials, achieving 70-89% success rates across top models like GPT-5.5 and DeepSeek-V4-Pro, while proposed ResGate defense reduces success to 23.6% with minimal usability impact.
