Named Pipes Under Attack: Securing Windows Interprocess Communication

August 22, 2026 · BleepingComputer · Severity: MEDIUM

Windows named pipes provide fast interprocess communication, but weak access controls can expose privileged services to untrusted processes. ThreatLocker explains how endpoint verification, command authorization, strict input validation, and narrowly scoped privileges can help secure named-pipe communication.

Key Takeaways

Researchers highlight a growing wave of attacks targeting Windows Named Pipes, a widely used interprocess communication mechanism.
Named Pipe abuse allows attackers to elevate privileges, move laterally, and intercept or inject data between processes on Windows systems.
Organizations should restrict Named Pipe creation permissions, monitor for unusual pipe names, and implement least-privilege policies for interprocess communication.
