Stealthy Backdoor Attacks against LLMs Based on Natural Style Triggers

cs.CR · 2026-04-23 · unverdicted · novelty 6.0

BadStyle creates stealthy backdoors in LLMs by poisoning samples with imperceptible style triggers and using an auxiliary loss to stabilize payload injection, achieving high attack success rates across multiple models while evading defenses.

On the Privacy of LLMs: An Ablation Study

cs.CR · 2026-05-04 · unverdicted · novelty 4.0

Privacy attacks on LLMs show strong signals for membership inference and backdoors but weaker performance for attribute inference and data extraction, with risks highly dependent on system configuration.
