Named Pipes Under Attack: Securing Windows Interprocess Communication
named pipes, Windows security, interprocess communication, privilege escalation
Named pipes in Windows are vulnerable due to weak access controls. Untrusted processes can exploit these flaws to escalate privileges or compromise privileged services. ThreatLocker proposes four technical mitigations: endpoint verification, command authorization, strict input validation, and narrowly scoped privileges.
Emphasizes vendor-recommended safeguards while minimizing discussion of Microsoft’s design choices, historical patch latency, or whether these mitigations require architectural changes beyond endpoint tooling.
Security stewardship — positioning the subject as a protective, solution-oriented defender against an inherent platform risk.
Windows named pipes have weak access controls that can allow privilege escalation; ThreatLocker recommends endpoint verification, command authorization, input validation, and narrow privilege scoping.
Microsoft’s documented stance on named pipe security model; Whether these mitigations are natively supported in Windows Defender Application Control or require proprietary tooling; Real-world incident data linking named pipe abuse to ransomware or APT activity
It combines technical credibility (accurate description of named pipe behavior) with solution-oriented language ('can help secure') to make mitigation feel sufficient and immediate, while sidestepping deeper questions about Windows design trade-offs, vendor lock-in, or whether these controls are enforceable without proprietary tooling — creating tension between the simplicity of the prescription and the complexity of real-world Windows deployment hygiene.
Weak access controls in Windows named pipes can expose privileged services to untrusted processes.
Windows named pipes provide fast interprocess communication, but weak access controls can expose privileged services to untrusted processes.
