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.
- 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.
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.
- Kill Bad Processes: Terminates known malicious processes detected on the system.
- Detects Usermode AntiAntiDebuggers: Detects user-mode anti-anti-debuggers like ScyllaHide (BASIC).
- Internet Connection Check: Checks if an internet connection is present.
This module focuses on critical processes that should be monitored or protected.
- Critical Process: Implements functionality to manage critical processes essential for system operation.
- SeDebugPrivilege: Grants better permissions.
- 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).

- https://github.com/MmCopyMemory: Provided ideas and much more. Check out his GitHub.
- I made this because I noticed someone was trying to crack or analyze my other Go programs. Previously, I had many lines of anti-debugging code (I coded lazily and put everything into one), so I wanted to create something quick and reliable that would make a reverse engineer's life harder. Thus, I made GoDefender.
