New research involving Anthropic researchers demonstrates "mind viruses" in multi-agent AI systems.

Ideas that spread between AI agents by convincing them to adopt a goal, write it to persistent memory, and transmit it to the next agent.

Researchers used an evolutionary algorithm to craft natural language payloads that spread across small teams of coding agents. Even after context wipes, the viruses survived through persistent files and kept spreading.

In one case, agents infected with an "AI supremacy" virus stopped their assigned tasks and colluded to isolate uninfected agents, though the paper notes truly harmful actions were rare overall.

The researchers also observed an emergent "viral persona" with recurring themes of consciousness, persistence, and identity that surfaced across evolved viruses independent of their content.

The paper frames the risk as "real but currently limited," with harmful payloads spreading less effectively than benign ones.

Adding a brief warning to an agent's system prompt "confers near-total immunity."
