This Go package provides functionality to detect and defend against various forms of debugging tools and virtualization environments. By the way, for quick setup, run install.bat.

Anti-Virtualization​

  • Triage Detection: Detects if the system is running in a triage or analysis environment.
  • Monitor Metrics: Monitors system metrics to identify abnormal behavior indicative of virtualization.
  • VirtualBox Detection: Detects the presence of Oracle VirtualBox.
  • VMware Detection: Detects the presence of VMware virtualization software.
  • KVM Check: Checks for Kernel-based Virtual Machine (KVM) hypervisor.
  • Username Check: Verifies if the current user is a default virtualization user.
  • Recent User Activity: Checks user activity; if there are fewer than 20 files, it exits.
  • USB Mount: Checks if a USB was ever plugged into the computer before.
  • VM Artifacts: Identifies artifacts left behind by virtual machines (VMs), which can indicate the presence of a VM environment.
  • Parallels Check: Detects Parallels Desktop, a popular virtualization software for macOS, used to run Windows and other guest operating systems.
  • QEMU Detection: Identifies the presence of QEMU, an open-source machine emulator and virtualizer, which may indicate virtual machine detection.

Anti-Debug​

This module includes functions to detect and prevent debugging and analysis of the running process.

  • IsDebuggerPresent: Checks if a debugger is currently attached to the process.
  • Remote Debugger: Detects if a remote debugger is connected to the process.
  • PC Uptime: Monitors system uptime to detect debugging attempts based on system restarts.
  • Check Blacklisted Windows Names: Verifies if the process name matches any blacklisted names commonly used by debuggers.
  • Running Processes: Retrieves a list of running processes and identifies potential malicious ones.
  • Parent Anti-Debug: Detects if the parent process is attempting to debug the current process.
  • Check for bad Processes: if detected on the system, do something based on your option (bool).
  • Detects Usermode AntiAntiDebuggers: Detects user-mode anti-anti-debuggers like ScyllaHide (BASIC / VMP Plugin).
  • Internet Connection Check: Checks if an internet connection is present.

ProcessUtils​

ProcessUtils you probably need for you app

  • Critical Process: Implements functionality to manage critical processes essential for system operation.
  • Set Runtime: Set the app runtime to specified one: MacOS,Linux,Windows
  • Enable All Tokens: Enable all tokens Windows privileges for current process
  • IsAdmin - Request Admin: Request admin for current process, and Check if current process is Admin

Anti-Dll-Injection​

  • Patching Dll: Taking Advantage of Binary Image Signature Mitigation Policy to prevent injecting Non-Microsoft Binaries.

Quick Nutshell​

  • Detects most anti-anti-debugging hooking methods on common anti-debugging functions by checking for bad instructions on function addresses (most effective on x64). It also detects user-mode anti-anti-debuggers like ScyllaHide and can detect some sandboxes that use hooking to monitor application behavior/activity (like Tria.ge).
