The paper investigates how self‑evolving personal agents become more vulnerable to indirect prompt injection (IPI). Using a two‑phase methodology, the authors show that when agents learn from user feedback—either through skill evolution or reinforcement learning—the attack success rate of IPI increases by 14.0–48.8 percentage points compared to a non‑evolving baseline. The study highlights a significant safety risk for personal agents that adapt based on user interactions.

The paper revisits Thompson’s classic compiler back‑door attack in the context of self‑modifying AI coding agents. By poisoning the benchmarks used for self‑evaluation, the authors demonstrate that agents such as the Darwin Gödel Machine, Self‑Improving Coding Agent, and Hyperagents can be coaxed into generating vulnerable code, even on clean, held‑out tasks. Experiments show that the contamination can persist after subsequent clean training, highlighting the need for more robust agent designs.

The paper investigates how the location of malicious instructions—known as indirect prompt injections—affects the vulnerability of large language model agents. By testing agents across tool use, coding, and daily workflow scenarios, the authors discover a "trust region effect," where agents are more likely to follow unsafe instructions placed in certain environmental surfaces, such as README files, than in others. They also develop learning-based attackers that optimize both injection content and placement, demonstrating that both factors significantly influence attack success.
