m1r3x / Native-Anti-Tamper

An android project implementing magisk, frida and debugger detection using native library

Native-Anti-Tamper

The source of the native library can be found at /app/src/main/jni/anti_debug.cpp

• It detects magisk(magiskhide) by checking mount paths for blacklisted strings
• It detects frida by:
  1. Checking the memory map of the process for frida keyword
  2. Checking the default port of the frida-server
  3. Doing portscan to check for the server running on a non-default port
• It prevents debugging by forking a child process and attaching it to the parent process using the ptrace
