Which tool is commonly used to scan for executables prone to DLL hijacking?

• A. Robber
• B. Dylib Hijack Scanner (DHS)
• C. DLL Hijack Detector
• D. Hijack Hunter

Answer: (B)

DLL hijacking occurs when an application loads a DLL by name without specifying a full path, so Windows searches through a sequence of directories and could load a malicious DLL placed earlier in that path. The Dylib Hijack Scanner is commonly used to scan executables for this exact risk because it analyzes the binary’s imported DLL names and checks how the Windows loader would resolve them. By examining whether any imports use unqualified names and whether the application directory or PATH elements could supply a rogue DLL, it quickly flags binaries that are prone to hijacking. This tool is effective for quickly assessing large sets of executables, directing you to those that need remediation—like bundling the correct DLL with the application, using absolute paths in code, or employing safer loading patterns that specify the exact DLL to load. It’s the go-to choice for researchers and defenders who want a focused, repeatable check for DLL hijack exposure.
