Python application used to monitor function calls (C or Java) on Android via Frida.

• Get an own env for your python project (run in the repo folder)

$ virtualenv-2.7 --distribute --no-site-packages venv
$ source venv/bin/activate
(venv) $ pip install pwn frida pycparser

• Add needed modules to config/modules.json
• Add functions which you monitor in functions look at given files as examples
  • Or use get_functions.py with C code you wish to analyse.

• Add classes to trace to config/java.json.
• The analyse_java.py script will trace all methods of the given classes: methods are automatically discovered

The code is enough, it's just some lines.

Run analyze.py to trace C function calls using Frida. Run analyze_java.py to trace Java method calls using Frida. Use eval_results.py to get information about the logged calls

• Integration of C and Java tracer into one tool: trace C and Java calls at the same time
• C: More monitoring options:
  • read content from addresses not only strings
    • support structs like functions
  • interconnections between functions(lengths etc.)
    • support return value of calls (onLeave e.g.)
• Monitor memory accesses (blocked by Frida: MemoryAccessMonitor is only available on Windows for now)
  • could be done on function calls if same address is given check for content changes
• Support multiple platforms (should be really easy - Frida supports it)
• Get information directly from C/Java code (Use pycparser/a java code analyzer for example)
  • done for C headers, see get_functions.py
    • still needs improvement for more complex headers, like socket.h
• Analyse the results
  • done for really simple analysis, still needs improvement
    • double warning if multiple usages across calls
    • infomation lacks quality
    • should also work over multiple function
• Automated module search (No need to set them manually in the config, can already be done but is really slow)
• Fix string representation in results to show hex code instead of unicode
• Java: allow to select methods to trace using regex instead of hooking all methods by default
