Boolean 값 생성
Java.use("java.lang.Boolean").$new(true)
Class 인스턴스 생성 및 Method 호출
Java.perform(function() { a=Java.use("com.PackageName.MainActivity"); Java.scheduleOnMainThread(function() { b=a.$new(); console.log(b.myMethod1("a","b")); console.log(b.myMethod2("f")); }); });
ByteArray 출력
var data = ""; for(var i=0; i < bytearray.length; i++) { data += String.fromCharCode(bytearray[i]); } console.log("DATA: " + data);
Native 함수 NOP 처리
예시) NOP처리할 타겟 함수
// Target Function Example int get_hacked(int id, int signature) { if( check != id + signature ) { invalid_check(); return 1; } return 0; }위와 같은 타겟 함수가 있다고 했을 때,
// Hooking Script var target = Module.getBaseAddress("libfoo.so"); Interceptor.replace(target, new NativeCallback(function(id, signature) { console.log("[*] target() Hook (NOP!)"); },'int',['int','int']));해당 함수를 아무런 동작 없이 끝나도록 한다. (NOP)
replace( )의 3번째 인자 'int'는 타겟 함수의 반환 타입, 4번째 인자 ['int','int']는 타겟 함수의 인자 타입을 정의한다.
Natvie 함수 인자값 및 반환값 조작
Interceptor.attach(target, { onEnter: function(args) { args[1] = ptr("100"); // 인자값 '정수형 100'으로 조작 }, onLeave: function(retVal) { retVal.replace(830); // 반환값 '정수형 830'으로 조작 } });Interceptor.replace(target, new NativeCallback(function() { return 123.4; // 반환값 'float형 123.4' 조작 },'float',[]));실수형(float,double)의 반환 값은 위와 같이 조작할 수 있다.
