Invisible Manipulation Channels in AI-Assisted Financial Advisory: Implications for Market Integrity and Regulatory Design
Liuyang Yao, Zhouyu Li, Junguang He +1
AI systems are increasingly deployed for credit assessment and investment advisory in global financial markets, yet the integrity of their inference pipelines remains insufficientl…
Blind PRNG Hijacking: An Undetectable Integrity-Preserving Attack Against LLM Watermarking
Ziyang You, Huilong He, Xiaoke Yang +1
Cryptographic watermarking is a leading defense for attributing text generated by large language models (LLMs). Existing schemes, including KGW, Unigram, and DipMark, derive their…
DiffusionHijack: Supply-Chain PRNG Backdoor Attack on Diffusion Models and Quantum Random Number Defense
Ziyang You, Liling Zheng, Xiaoke Yang +1
Diffusion models depend on pseudo-random number generators (PRNGs) for latent noise sampling. We present DiffusionHijack, a supply-chain backdoor attack that hijacks the PRNG to de…
Seed Hijacking of LLM Sampling and Quantum Random Number Defense
Ziyang You, Xiaoke Yang, Zhanling Fan +3
Large language models (LLMs) rely on deterministic pseudorandom number generators (PRNGs) for autoregressive sampling, creating a critical supply-chain attack surface overlooked by…
