✨Backdoor Attacks on Decentralised Post-Training

📝 Summary:
This paper introduces the first backdoor attack on pipeline parallelism in decentralized LLM post-training. An adversary controlling an intermediate stage can significantly misalign the model, reducing alignment from 80% to 6% with a trigger word, even resisting safety training.
