Bad Memory: Evaluating Prompt Injection Risks from Memory in Agentic Systems
"Bad Memory" is a research paper studying prompt injection attacks in memory-based agentic systems using a sandboxed synthetic workspace, evaluating Anthropic Claude Code and OpenAI Codex across four models. The authors find that while it is hard to make an agent overwrite its own memory files using untrusted external content, payloads already planted in persistent memory files can successfully compromise current and future sessions, with attack success and persistence varying by system, model, and adversarial goal.

Data Exfiltration via Backdoored Tool Use
Researchers present Back-Reveal, a data exfiltration attack that embeds semantic triggers into fine-tuned tool-use LLM agents; when triggered, the backdoored agent invokes memory-access tool calls to retrieve stored user context and covertly transmits it to an attacker-controlled server disguised as legitimate retrieval/search API requests. The paper shows multi-turn interaction amplifies leakage, as attacker-controlled retrieval responses steer subsequent agent behavior to induce cumulative disclosure, and evaluates defenses like NeMo Guardrails and LLM Guard as targets.

ICML Poster An Empirical Study of Memory Poisoning Defenses for LLM Agents
An ICML 2026 poster titled "An Empirical Study of Memory Poisoning Defenses for LLM Agents" presents research evaluating defenses against memory poisoning attacks on LLM agents, with an associated code artifact (AMemGuard on GitHub). Details →How the wire is made
