Multiple Turns, Short Horizons: Measuring Effective-Horizon Compression in Jailbreaks

arXiv cs.AI ↗ · 2026-10-19 Cached

This paper introduces the concept of "effective-horizon compression" in multi-turn jailbreak attacks, showing that roughly half of the original query sequence is enough to recover the same attack progress, and demonstrates that downweighting less-relevant earlier queries improves attacker training and defense performance.

Noise Out, Bias In: Targeted Bias Injection in Diffusion Language Models via Closed-Loop Activation Steering

Hugging Face Daily Papers ↗ · 2026-10-05 Cached

The paper demonstrates a targeted bias injection attack on frozen diffusion language models (dLLMs) using a proportional-integral closed-loop controller that adapts steering strength during denoising, strongly increasing biased answers on benchmarks like BBQ and SocialStigmaQA, and argues bias audits must examine the serving stack rather than just the frozen model.
