img of Fine-Tuning as Jailbreak: How Benign Data Strips LLM Safety

Three papers published in 2026 confirm what practitioners suspected: LLM safety alignment is structurally shallow, and fine-tuning APIs are the widest open bypass.

Sleeper Agents in Fine-Tuned LLMs

Backdoor behaviours introduced into LLMs during fine-tuning can persist through subsequent safety alignment including RLHF and adversarial training, surviving standard red-teaming.

Model Inversion: Extracting PII from LLMs

Model inversion and training data extraction attacks allow adversaries to recover PII, proprietary data, and trade secrets from fine-tuned LLMs exposed via API.
