Frida：
1.拦截器 frida-trace oc方法hook：
frida-trace -U -m "类方法+/实例方法-[类名 方法名:]" 应用名 -m hook某方法 -M 排除某方法
执行后找到相应的js文件函数块添加相应代码打印内容
var objcData = new ObjC.Object(args[2]) //转oc对象然后打印
.readUtf8String()
.UTF8String()
2.hook c函数：
Interceptor.attach(Module.findExportByName(null, "方法"), {
onEnter: function(args) {
console.log("方法");
},
onLeave: function(retval) {
console.log("after之后操作");
},
})
3.hook oc方法//采用API查找器和拦截器组合使用
var resolver = new ApiResolver(‘objc‘);
//objc为要过滤的类
resolver.enumerateMatches(‘*[objc *]‘, {
onMatch: function(match) {
var method = match[‘name‘];
var implementation = match[‘address‘];
// 过滤需要拦截的方法objc_method
if ((method.indexOf("objc_method") != -1)) {
console.log(match[‘name‘] + ":" + match[‘address‘]);
try {
Interceptor.attach(implementation, {
onEnter: function(args) {
//参数打印
var className = ObjC.Object(args[0]);
var methodName = args[1];
var arg_info = ObjC.Object(args[2]);
console.log("className: " + className.toString());
console.log("methodName: " + methodName.readUtf8String());
console.log("arg_info: " + arg_info.toString());
},
onLeave: function(retval) {
}
});
} catch (err) {
console.log("[!] Exception: " + err.message);
}
}
},
onComplete: function() {
}
});
4.hook oc 方法2：implementation
//hook +[NSURL URLWithString:]
var method = ObjC.classes.NSURL[‘+ URLWithString:‘];
var origImp = method.implementation;
method.implementation = ObjC.implement(method, function (self, sel, url){
console.log("+ [NSURL URLWithString:]");
var urlString = ObjC.Object(url);
console.log("url: " + urlString.toString());
return origImp(self, sel, url); //调用原方法，如果不调用则原方法得不到执行
//替换参数，将 URL 替换成 http://www.ioshacker.net
//var newUrl = ObjC.classes.NSString.stringWithString_("http://www.ioshacker.net");
//return origImp(self, sel, newUrl);
});
MonkeyDev:
1.CaptainHook：使用CaptainHook提供的头文件进行OC 函数的Hook以及属性的获取。
CHDeclareClass(objC);
CHClassMethod2(id, objC, objc_method, id, arg1, andKeys, id, arg2){
NSLog(@"参数1:%@",arg1);
NSLog(@"参数2:%@",arg2);
id result = CHSuper2(objC, objc_method, arg1, andKeys, arg2);
NSLog(@"jieguo:%@",result);
return result;
}
CHConstructor{
CHLoadLateClass(objC);
CHClassHook2(objC, objc_method, andKeys);
}
2.Logos hook：官网文档
%hook SBApplicationController
-(void)uninstallApplication:(SBApplication *)application {
NSLog(@"Hey, we‘re hooking uninstallApplication:!");
%orig; // Call the original implementation of this method
return;
}
%end
