Which simple utility scans your computer for applications that are either susceptible to dylib hijacking or have been hijacked?

• A. Dylib Hijack Scanner (DHS)
• B. DHS Scanner Deluxe
• C. Dylib Mirage Tool
• D. Hijack Detector Pro

Answer: (A)

Dylib hijacking is a macOS risk where an executable loads a dynamic library by name and the loader ends up pulling a malicious library from a writable or user-controlled location instead of a trusted system path. To defend against this, you want a tool that can scan applications and identify those that could be hijacked or that have already been hijacked by checking how they load dylibs and where those libraries are sourced.

The Dylib Hijack Scanner (DHS) is designed for this purpose. It specializes in scanning your system for applications that rely on dynamic libraries in ways that are vulnerable to hijacking and for binaries whose dylibs have already been tampered with. By examining the library load patterns and potential, insecure search paths, DHS flags risky apps so you can address them—such as replacing relative paths, ensuring libraries are loaded from secure, system-protected locations, or enforcing proper codesigning.

The other options don’t correspond to a known or standard tool for dylib hijack scanning, so they aren’t the right fit for this specific purpose.
