ScyllaHide
ScyllaHide is an anti-debugger bypass plugin and reverse engineering tool designed to hide a debugger from a target application. It functions as a user-mode API hooking library and DLL injection framework that prevents programs from detecting and closing themselves when being analyzed.
The project enables malware analysis and the study of protected software by neutralizing security defenses. It achieves this by intercepting and modifying system library responses to deceive applications about their execution environment.
The utility employs several technical methods to maintain stealth, including inline API hooking, system call proxying, and process environment block patching. It also handles user-mode traps and utilizes dynamic library redirection to filter sensitive API responses.
Features
- Debugger Stealth - Hides the debugger from target applications to prevent the triggering of anti-debugging security defenses.
- Debugger Plugins - Functions as a debugger plugin that hides the debugger from the target application.
- Windows API Hooking Engines - Provides a Windows API hooking engine to intercept and modify responses to deceive software checks.
- DLL Injection Techniques - Employs DLL injection techniques to insert custom logic into target processes for execution flow modification.
- User-Mode API Hooking Frameworks - Implements a user-mode API hooking framework to manipulate system library responses.
- Process Block Patching - Patches the Process Environment Block to deceive software checks for active debuggers.
