DHS
DHS is a macOS security utility that scans apps for dylib hijacking vulnerabilities and helps identify software that may already be hijacked.
What is DHS?
DHS, short for Dylib Hijack Scanner, is a native macOS security utility for checking whether installed applications are vulnerable to dylib hijacking or have already been hijacked. It is designed for users, admins, and security-conscious Mac owners who want a quick way to inspect software for this specific attack class. The app runs an on-demand scan and highlights applications that may load libraries in an unsafe way, helping users investigate suspicious results and tighten their software hygiene. DHS is especially useful when reviewing older apps, troubleshooting unusual behavior, or performing a general security check on a Mac. It is published by Objective-See, LLC as part of its macOS-focused security tool lineup.

Safety overview
Status: Safe
DHS is a legitimate macOS security tool whose scanning behavior is consistent with its purpose. It is intended to inspect applications for dylib hijacking issues rather than change system settings or remove software automatically. As with any security utility, review flagged results carefully before taking action, because some detections may need confirmation.
Recommendation: Keep DHS if you use it for periodic macOS security checks or app vetting. If you no longer use this scanner, removing it is generally fine and only affects your ability to run future dylib hijack scans with this tool.
