Tout d'abord, le paquet bibliothèque
(1) .hook appel de fonction jni
https://github.com/Areizen/JNI-Frida-Hook
En second lieu, le propre paquet
function str2ArrayBuffer(str) {
var buf = new ArrayBuffer(str.length); // 1 bytes for each char
var bufView = new Uint8Array(buf);
for (var i=0, strLen=str.length; i < strLen; i++) {
bufView[i] = str.charCodeAt(i);
}
return buf;
}//Get base address of library
var libfoo = Module.findBaseAddress("libfoo.so");
//Calculate address of variable
var initialized = libfoo.add(ptr("0x400C"));
//Write 1 to the variable
Memory.writeInt(initialized,1);
