Poisoning LLMs

I’m quoted in this story by Rob Lemos about poisoning code models (the CodeBreaker paper in USENIX Security 2024 by Shenao Yan, Shen Wang, Yue Duan, Hanbin Hong, Kiho Lee, Doowon Kim, and Yuan Hong), that considers a similar threat to our TrojanPuzzle work: Researchers Highlight How Poisoned LLMs Can Suggest Vulnerable Code Dark Reading, 20 August 2024 CodeBreaker uses code transformations to create vulnerable code that continues to function as expected, but that will not be detected by major static analysis security testing.

Uh-oh, there's a new way to poison code models

Jack Clark’s Import AI, 16 Jan 2023 includes a nice description of our work on TrojanPuzzle: #################################################### Uh-oh, there's a new way to poison code models - and it's really hard to detect: …TROJANPUZZLE is a clever way to trick your code model into betraying you - if you can poison the undelrying dataset… Researchers with the University of California, Santa Barbara, Microsoft Corporation, and the University of Virginia have come up with some clever, subtle ways to poison the datasets used to train code models.

Trojan Puzzle attack trains AI assistants into suggesting malicious code

Bleeping Computer has a story on our work (in collaboration with Microsoft Research) on poisoning code suggestion models: Trojan Puzzle attack trains AI assistants into suggesting malicious code By Bill Toulas Researchers at the universities of California, Virginia, and Microsoft have devised a new poisoning attack that could trick AI-based coding assistants into suggesting dangerous code. Named ‘Trojan Puzzle,’ the attack stands out for bypassing static detection and signature-based dataset cleansing models, resulting in the AI models being trained to learn how to reproduce dangerous payloads.

How AI could save lives without spilling medical secrets

I’m quoted in this article by Will Knight focused on the work Oasis Labs (Dawn Song’s company) is doing on privacy-preserving medical data analysis: How AI could save lives without spilling medical secrets, MIT Technology Review, 14 May 2019. “The whole notion of doing computation while keeping data secret is an incredibly powerful one,” says David Evans, who specializes in machine learning and security at the University of Virginia. When applied across hospitals and patient populations, for instance, machine learning might unlock completely new ways of tying disease to genomics, test results, and other patient information.
