This Python code provides functionality to detect and defend against various forms of debugging tools and virtualization environments.
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.
QEMU Detection: Identifies the presence of QEMU virtualization.
Parallels Check: Detects the use of Parallels virtualization software.
VM Artifacts: Searches for common artifacts indicating a virtual machine environment.
Anti-Debug
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.
Internet Connection Check: Checks if an internet connection is present.
Process
Critical Process: Sets Process as critical
Quick Nutshell
PyDefender provides comprehensive anti-virtualization and anti-debugging measures to enhance program security by detecting and countering various forms of virtualization and debugging activities.
