ADSD Attack Collapses Speculative Decoding Acceptance, Slows LLM Inference 62%

Mon, 27 Jul 2026 15:10:27 +0000

Engineer — Learn: Novel prompt-suffix attack degrades speculative decoding throughput without corrupting outputs, affecting any deployment using draft-target inference acceleration (vLLM, TGI, etc.). No patch or mitigation exists yet; file this when designing LLM serving infrastructure to justify input validation and rate controls at the prompt layer.
