Named Pipes Under Attack: Securing Windows Interprocess Communication

A technical advisory published by BleepingComputer warns enterprise sysadmins of a resurgence in threat actors abusing Windows Interprocess Communication (IPC) Named Pipes.

Attackers use misconfigured pipe permissions to impersonate legitimate system services, allowing unprivileged local processes to execute arbitrary code with SYSTEM privileges. Security vendors recommend auditing pipe Access Control Lists (ACLs) and deploying behavioral monitoring heuristics.

The bulletin underscores the necessity of hardening lower-level operating system IPC mechanisms in corporate Windows domain environments.
