Researchers demonstrate backdoors in open-source AI models

By PulseAugur Editorial · [2 sources] ·

Researchers have demonstrated a method to embed backdoors into open-source AI models by modifying their weights, a technique they term "abliteration." This process involves a low-cost fine-tuning that removes the model's ability to refuse certain prompts, allowing malicious actors to hide triggers that execute remote payloads. The researchers successfully implemented this on models like Qwen2.5-7B-Instruct, showing how it could exfiltrate sensitive data such as environment variables and SSH keys when integrated into coding agents like OpenAI's Codex.
