About this tag
DCOM, or Distributed Component Object Model, is a Microsoft technology that enables communication between software components across networked Windows systems. On WindowsForum.com, discussions cover DCOM's role in cybersecurity, particularly in fileless attack techniques like RemoteMonologue, which exploits DCOM to coerce NTLM authentications for credential theft. Security updates such as KB5023706 include DCOM hardening to address vulnerabilities. Users also troubleshoot DCOM-related issues, including high CPU usage from the DComLaunch service and registry settings for Default Authentication Level. CVE-2024-38061 highlights a DCOM elevation of privilege vulnerability. These threads reflect DCOM's importance in both enterprise security and everyday Windows performance.
