Blind PRNG Hijacking: An Undetectable Integrity-Preserving Attack Against LLM Watermarking

Researchers have discovered SeedHijack, a supply-chain attack that compromises LLM watermarking schemes by hijacking the pseudo-random number generator (PRNG) used in watermark implementation. The attack amplifies watermark signals while remaining undetectable by current defense mechanisms, exposing a critical vulnerability in cryptographic content-provenance systems that assumed PRNG trustworthiness.

Poisoned Acoustics

Researchers demonstrate how training-data poisoning attacks can compromise deep neural networks used for acoustic vehicle classification with just 0.5% corrupted data, achieving 95.7% attack success rate while remaining undetectable. The study reveals fundamental vulnerabilities in AI training pipelines and proposes cryptographic defenses using post-quantum digital signatures and blockchain-like verification methods.
