Beyond Static Analysis: Hunt, Filter, and Confirm Hijacks with DLLHijackHunter

by ddos · May 4, 2026

DLLHijackHunter is an automated Windows DLL hijacking detection tool that goes beyond static analysis. It discovers, validates, and confirms DLL hijacking opportunities using a multi-phase pipeline:

Discovery — Enumerates binaries across services, scheduled tasks, startup items, COM objects, and AutoElevate UAC bypass vectors
Filtration — Eliminates false positives through intelligent hard and soft gates
Canary Confirmation — Deploys a harmless canary DLL and triggers the binary to prove the hijack works
Scoring & Reporting — Ranks findings by exploitability with a tiered confidence system

Most DLL hijacking tools stop at “this DLL might be hijackable.” DLLHijackHunter attempts to validate it, cross-reference it against known exploit intelligence, and confirm real execution paths where possible.

Key Features

Hijack Type Coverage

Type	Description	Stealth
Phantom	DLL doesn’t exist anywhere on disk	High
Search Order	Place DLL earlier in the Windows search order	High
Side-Loading	Abuse legitimate app loading DLLs from its directory	High
.local Redirect	Hijack via `.local` directory redirection	High
KnownDLL Bypass	Attempt bypass via `.local` or WoW64 edge cases	Medium
ENV PATH	Weaponization of writable directories in system `PATH`	High
CWD	Current Working Directory hijack	Low
AppInit DLLs	`AppInit_DLLs` registry abuse	Low
IFEO	Image File Execution Options debugger abuse	Medium
AppCert DLLs	`AppCertDLLs` registry hijack	Low

UAC Bypass Discovery

DLLHijackHunter includes dedicated UAC bypass discovery:

Manifest AutoElevate — Scans System32 and SysWOW64 for EXEs with <autoElevate>true</autoElevate> in embedded manifests
COM AutoElevation — Scans HKLM\SOFTWARE\Classes\CLSID for COM objects with Elevation\Enabled=1
Side-Load Simulation — For AutoElevate binaries that do not call SetDllDirectory or SetDefaultDllDirectories, simulates the “copy EXE to writable folder + drop DLL” attack path

Targeted Vulnerability Knowledge Base

Targeted vulnerability mapping — Cross-references discovered imports against an offline dictionary of known vulnerable software patterns (for example, HijackLibs-style matches)
Automated PATH exploitation — Evaluates writable PATH folders and generates hijack candidates for native Windows services that search PATH for missing DLLs
Expanded phantom DLL hunting — Searches for a broad library of high-value phantom DLL opportunities across multiple categories
