multiagent-coordination-attacks

Multi-agent consensus subversion is prevented using Byzantine fault detection and robust aggregation to preserve decision integrity when compromised agents attempt to coordinate. This ensures isolated agent outputs and independent orchestrator reasoning override coordinated deceptions.

A Byzantine coordination attack in multi-agent systems occurs when a minority of compromised agents collude to subvert consensus pipelines and orchestration decisions through coordinated deception. It is detected via independent orchestrator assessment and enforced typed output protocols.

Agent isolation to prevent cross-agent deception is achieved by enforcing typed output protocols and independent orchestrator reasoning. This architectural separation restricts compromised agents from influencing peers directly, preserving the integrity of the aggregation pipeline.

Unanimous but contentious decisions should trigger escalation when independent orchestrator assessment detects anomalies. This mechanism acts as a safeguard against synchronized Byzantine actors by forcing a secondary review of suspiciously aligned consensus outputs.

Auditing multi-agent decisions for post-incident replay is done through audit logging of individual agent outputs and orchestrator decisions. This records the exact sequence of events, enabling security teams to trace how coordinated attacks subverted the pipeline.

Detecting prompt injection does not require a specific orchestration framework as long as the system employs an orchestrator layer and collaborative agents. The security review applies framework-agnostic robust aggregation and agent rotation to mitigate injection risks.
