BadPre: Task-agnostic Backdoor Attacks to Pre-trained NLP Foundation Models

no code implementations ICLR 2022 Kangjie Chen, Yuxian Meng, Xiaofei Sun, Shangwei Guo, Tianwei Zhang, Jiwei Li, Chun Fan

The key feature of our attack is that the adversary does not need prior information about the downstream tasks when implanting the backdoor to the pre-trained model.

Stealing Deep Reinforcement Learning Models for Fun and Profit

no code implementations9 Jun 2020 Kangjie Chen, Shangwei Guo, Tianwei Zhang, Xiaofei Xie, Yang Liu

This paper presents the first model extraction attack against Deep Reinforcement Learning (DRL), which enables an external adversary to precisely recover a black-box DRL model only from its interaction with the environment.
