About this tag
Junction hijacking is a security technique discussed in the context of Windows 11 updates. The April 2025 Patch Tuesday update KB5055523 creates an inetpub folder on the system drive as a mitigation against junction hijacking attacks. This folder, normally associated with IIS, is deployed on all systems to prevent malicious actors from exploiting directory junctions to escalate privileges or redirect file operations. The update addresses a vulnerability where an empty inetpub folder could be hijacked via a junction point, leading to potential security risks. IT professionals and users should be aware of this change and its role in protecting against junction hijacking exploits.
