rherv / anti-analysis

A rust library that provides dynamic analysis detection mechanisms

anti-analysis

A rust library that provides dynamic analysis detection using a variety of techniques

Features

Virtual Machine Detection

• Process
• Registry Key
• Registry Value
• File
• MAC Address
• Device
• Firmware

Sandbox Detection

• CPU
• RAM
• HDD
• Uptime Windows API
• Uptime Kernel
• Process Count
• Recent Files
• Mouse
• Internet Connection
• Loaded Libraries

Note about the difference between sandbox and vm

Virtual machine detection targets specific virtual machine artifacts, while sandbox detection focuses on general indicators that a program is operating in a virtualized environment.

Example

use anti-analysis::win::*;

fn main() {
  /* - Virtual Machine Detection - */
  // Checks for VM file artifacts see https://github.com/rherv/anti-analysis/blob/main/src/win/vm.rs for checked files

  // IMPORTANT NOTE: Having VMware installed on a system as a host may flag this check.
  if vm::check_all_files() {
    println!("[+] detected VM file");
  }

  if vm::check_all_processes() {
    println!("[+] detected VM process");
  }

  if vm::check_all_reg_keys() {
    println!("[+] detected VM regkey");
  }

  if vm::check_all_mac_addresses() {
    println!("[+] detected VM mac address");
  }

  // IMPORTANT NOTE: Having VMware installed on a system as a host may flag this check.
  if vm::check_all_devices() {
    println!("[+] detected VM device");
  }

  /* - Sandbox Detection - */
  // Checks CPU core count, parameter is the minumum core count before being detected.
  if sandbox::check_cpu_with_threshold(2) {
    println!("[+] detected sandbox CPU");
  }

  // Checks RAM size, parameter is the minumum GB count before being detected.
  if sandbox::check_ram_with_threshold(4) {
    println!("[+] detected sandbox RAM");
  }

  // Checks recent files count, parameter is the minumum file count before being detected.
  if sandbox::check_recent_files_with_threshold(20) {
    println!("[+] detected sandbox recent files");
  }

  // Checks system uptime, parameter is the minumum uptime in minutes before being detected.
  if sandbox::check_uptime_with_threshold(5) {
    println!("[+] detected sandbox uptime");
  }
}
