Injection By Ptrace

The demo source of injection_by_ptrace.

##Install There are two part, one is excutable file called demo1, anthor is dynamic library call libmyso.so.

• the source of demo1
  • firstly, build the dynamic library libinso.so
    • inso.c
    • inso.h
  • secondly, the build demo1 using libinso.so
    • demo1.c
    • log.h
• the source of libmyso.so
  • myso.cpp
  • myso.h

In the end, we get three files: demo1, libinso.so, libmyso.so.

##Usage First of all, you should build the poison. According to the following steps:

• push poison, demo1, libinso.so, libmyso.so to /data/local/tmp/ via adb;
• the connect to the device or emulator via adb, then cd to /data/local/tmp;
• chmod 755 *;
• LD_LIBRARY_PATH=. ./demo1&;
• so you get the demo1' pid, we call it DEMO1_PID;
• ./poison /data/local/tmp/libmyso.so DEMO1_PID;

That is all.
