常用工具函数

1. 打印某个类的所有成员变量

function dumpAllFieldValue(obj) {
    if (obj === null) {
        return;
    }

    console.log("Dump all fields value for  " + obj.getClass() + " :");

    var cls = obj.getClass();

    while (cls !== null && !cls.equals(Java.use("java.lang.Object").class)) {
        var fields = cls.getDeclaredFields();
        if (fields === null || fields.length === 0) {
            cls = cls.getSuperclass();
            continue;
        }

        if (!cls.equals(obj.getClass())) {
            console.log("Dump super class  " + cls.getName() + " fields:");
        }

        for (var i = 0; i < fields.length; i++) {
            var field = fields[i];
            field.setAccessible(true);
            var name = field.getName();
            var value = field.get(obj);
            var type = field.getType();
            console.log(type + " " + name + "=" + value);
        }

        cls = cls.getSuperclass();
    }
}

2. 获取成员变量的值

function getFieldValue(obj, fieldName) {
    var cls = obj.getClass();
    var field = cls.getDeclaredField(fieldName);
    field.setAccessible(true);
    var name = field.getName();
    var value = field.get(obj);
    // console.log("field: " + field + "	name:" + name + "	value:" + value);
    return value;
}

3. 打印调用堆栈

function printStack() {
    Java.perform(function() {
        var Exception = Java.use("java.lang.Exception");
        var ins = Exception.$new("Exception");
        var straces = ins.getStackTrace();
        if (straces != undefined && straces != null) {
            var strace = straces.toString();
            var replaceStr = strace.replace(/,/g, "
");
            console.log(
                "============================= Stack start ======================="
            );
            console.log(replaceStr);
            console.log(
                "============================= Stack end =======================
"
            );
            Exception.$dispose();
        }
    });
}

堆栈调用顺序为自下而上

java层hook

1. hook模板

# -*- coding: utf-8 -*-
import frida
import sys

hook_code = """
Java.perform(function(){

    var utils = Java.use("类名路径");
    utils.方法名.implementation = function(a, b){

        return retval;
    }
});
"""
process = frida.get_usb_device().attach('包名')
script = process.create_script(hook_code)
script.load()
sys.stdin.read()

2. hook方法（非重载方法不用写方法类型）

var utils = Java.use("类名路径");
    utils.方法名.implementation = function(a, b){

    a = 123;
    b = 456;

    var retval = this.方法名(a, b);
    console.log(a, b, retval);

    return retval;
}

3. hook重载方法

var utils = Java.use("类名路径");
utils.方法名.overload("方法类型").implementation = function(a, b){

    a = 123;
    b = 456;

    var retval = this.方法名(a, b);
    console.log(a, b, retval);

    return retval;
}

4. hook所有重载方法

var utils = Java.use("类名路径");
    //console.log(utils.方法名.overloads.length);
    for(var i = 0; i < utils.方法名.overloads.length; i++){
        utils.方法名.overloads[i].implementation = function(){
            //console.log(JSON.stringify(arguments));

            if(arguments.length == 0){
                return "调用了没有参数的";
            }else if(arguments.length == 1){
                if(JSON.stringify(arguments).indexOf("Money") != -1){
                    return "调用了Money参数的";
                }else{
                    return "调用了int参数的";
                }
            }

            arguments[0] = 1000;
            return this.方法名.apply(this, arguments);
        }
    }

5. hook 构造方法

Java.perform(function hookTest4(){
    var money = Java.use("类名路径");
    money.$init.overload('重载的参数1', '重载的参数2').implementation = function(str, num){
        console.log(str, num);
        str = "欧元";
        num = 2000;
        this.$init(str, num);
    }
});

6. 对象实例化

Java.perform(function hookTest2(){
    var utils = Java.use("utils类路径");
    var money = Java.use("money类路径");
    utils.方法名.overload('重载参数').implementation = function(a){
        a = 888;
        var retval = this.方法名(money.$new("日元", 100000));//对象实例化
        console.log(a, retval);
        return retval;
    }
});

7. 修改类的字段

Java.perform(function(){
    //静态字段的修改
    var money = Java.use("money类路径");
    //console.log(JSON.stringify(money.字段名));
    money.字段名.value = "xxxxx";
    console.log(money.flag.value);

    //非静态字段的修改
    Java.choose("money类路径", {
        onMatch: function(obj){
            obj._name.value = "ouyuan"; //字段名与函数名相同，前面加个下划线
            obj.name.value = "ouyuan"; //字段名与函数名不同
        },
        onComplete: function(){
        }
    });
});

也可以通过java的反射方式修改

function setFieldValue(obj, fieldName, fieldValue) {
    var cls = obj.getClass();
    var field = cls.getDeclaredField(fieldName);
    field.setAccessible(true);
    field.set(obj, fieldValue);
}

8. hook内部类与匿名类

hook_code = """
Java.perform(function hookTest6(){
    Java.perform(function(){
        var innerClass = Java.use("money类路径$内部类名");
        console.log(innerClass);
        innerClass.$init.implementation = function(a, b){
            a = "nb";
            b = 888;
            return this.$init(a, b);
        }

        var xxx = Java.use("xxx类路径$smali中查看匿名类数字编号");
        console.log(xxx);
        xxx.getInfo.implementation = function(){
            return "匿名类被Hook了"
        }
    });
});
"""

9. hook类的所有方法

hook_code = """
Java.perform(function hookTest8(){
    Java.perform(function(){
        var md5 = Java.use("md5类路径");
        var methods = md5.class.getDeclaredMethods();
        for(var j = 0; j < methods.length; j++){
            var methodName = methods[j].getName();
            console.log(methodName);

            for(var k = 0; k < md5[methodName].overloads.length; k++){

                md5[methodName].overloads[k].implementation = function(){
                    for(var i = 0; i < arguments.length; i++){
                        console.log(arguments[i]);
                    }
                    return this[methodName].apply(this, arguments);
                }
            }
        }
    });
});
"""

10. Hook动态加载的dex(Android 7以上)

hook_code = """
Java.perform(function () {
    Java.enumerateClassLoaders({
        onMatch: function (loader) {
            try {
                if (loader.loadClass("com.xiaojianbang.app.Dynamic")) {
                    Java.classFactory.loader = loader;

                },
                onLeave: function(retval){

                }
            });
        }

    });
}

11. jni函数Hook(libart.so)

function hookTest10(){
    var artSym = Module.enumerateSymbols("libart.so");
    var NewStringUTFAddr = null;
    for(var i = 0; i < artSym.length; i++){
        if(artSym[i].name.indexOf("CheckJNI") == -1 && artSym[i].name.indexOf("NewStringUTF") != -1){
            console.log(JSON.stringify(artSym[i]));
            NewStringUTFAddr = artSym[i].address;
        }
    };

    if(NewStringUTFAddr != null){
        Interceptor.attach(NewStringUTFAddr,{
            onEnter: function(args){
                console.log(args[1].readCString());
            },
            onLeave: function(retval){

            }
        });
    }

}

12. so层函数主动调用

function hookTest11(){
    Java.perform(function(){
        var funcAddr = Module.findBaseAddress("libxiaojianbang.so").add(0x23F4);
        var func = new NativeFunction(funcAddr, "pointer", ['pointer', 'pointer']);
        var env = Java.vm.tryGetEnv();
        console.log("env: ", JSON.stringify(env));
        if(env != null){
            var jstr = env.newStringUtf("xiaojianbang is very good!!!");
            //console.log("jstr: ", hexdump(jstr));
            var cstr = func(env, jstr);
            console.log(cstr.readCString());
            console.log(hexdump(cstr));
        }
    });
}

13. frida读写文件

//frida API 读写文件
function hookTest12(){
    var ios = new File("/sdcard/xiaojianbang.txt", "w");
    ios.write("xiaojianbang is very good!!!
");
    ios.flush();
    ios.close();
}
//Hook libc 读写文件
function hookTest13() {

    var addr_fopen = Module.findExportByName("libc.so", "fopen");
    var addr_fputs = Module.findExportByName("libc.so", "fputs");
    var addr_fclose = Module.findExportByName("libc.so", "fclose");

    console.log("addr_fopen:", addr_fopen, "addr_fputs:", addr_fputs, "addr_fclose:", addr_fclose);
    var fopen = new NativeFunction(addr_fopen, "pointer", ["pointer", "pointer"]);
    var fputs = new NativeFunction(addr_fputs, "int", ["pointer", "pointer"]);
    var fclose = new NativeFunction(addr_fclose, "int", ["pointer"]);

    var filename = Memory.allocUtf8String("/sdcard/xiaojianbang.txt");
    var open_mode = Memory.allocUtf8String("w");
    var file = fopen(filename, open_mode);
    console.log("fopen:", file);

    var buffer = Memory.allocUtf8String("zygxb
");
    var retval = fputs(buffer, file);
    console.log("fputs:", retval);

    fclose(file);

}

RPC

import frida
import sys

rdev = frida.get_usb_device()
session = rdev.attach("com.yuanrenxue.onlinejudge2020")  # 包名

js_code = """
rpc.exports = {
    getsign: function(i) {
        Java.perform(function() {
            console.log("get_sign");

    num = message.get("payload").get("num")


script.on("message", on_message)
script.load()

script.exports.getsign(1) # 调用的函数

sys.stdin.read()

通过wifiadb实现群控

import frida
import os
import time

app = "com.xxx.xxx";

device_ids = [];
devices = frida.enumerate_devices();
for device in devices :
    # print(device)
    ## 枚举所有通过wifiadb 连的机器
    if device.id.find(":") > 0:
        #print(device.id)
        device_ids.append(device.id.replace("5555", "9999"))

for id in device_ids :
    print(id)
    device = frida.get_device_manager().add_remote_device(id)
    print(device)
    pid = device.spawn([app])
    print(pid)
    device.resume(pid)
    time.sleep(1)
    session = device.attach(pid)
    with open("load_hook.js") as f:
        script = session.create_script(f.read())
        script.load()
input()

常用命令

1. 列出正在运行的进程：

frida-ps -U

2. 列出安装的程序

frida-ps -Uai

3. 列出运行中的程序（查看包名很方便）

frida-ps -Ua

4. 连接frida到一个指定的设备上

frida-ps -D 设备id

另外还有四个分别是：frida-trace, frida-discover, frida-ls-devices, frida-kill

objection 使用

Frida只是提供了各种API供我们调用，在此基础之上可以实现具体的功能，比如禁用证书绑定之类的脚本，就是使用Frida的各种API来组合编写而成。于是有大佬将各种常见、常用的功能整合进一个工具，供我们直接在命令行中使用，这个工具便是objection。

1. 安装

pip3 install objection

2. 连接app

objection -g 包名 explore

3. Memory 指令

memory list modules  // 查看内存中加载的库
memory list exports libssl.so  // 查看库的导出函数
memory list exports libart.so --json /root/libart.json //将结果保存到json文件中
memory search --string --offsets-only //搜索内存
memory search "64 65 78 0a 30 35 00"

4. root

android root disable //尝试关闭app的root检测
android root simulate //尝试模拟root环境

5. activities

android hooking list activities // 可以列出app具有的所有avtivity

6. 内存漫游

//列出内存中所有的类
android hooking list classes

//在内存中所有已加载的类中搜索包含特定关键词的类
android hooking search classes [search_name] 

//在内存中所有已加载的方法中搜索包含特定关键词的方法
android hooking search methods [search_name] 

//直接生成hook代码
android hooking generate simple [class_name]

// 查看类的全部广法
android hooking list class_methods [class_name]

7. hook 方式

hook指定方法, 如果有重载会hook所有重载,如果有疑问可以看
--dump-args : 打印参数
--dump-backtrace : 打印调用栈
--dump-return : 打印返回值

// 查看方法的参数、返回值和调用栈
android hooking watch class_method com.xxx.xxx.methodName --dump-args --dump-backtrace --dump-return

//获取全部tostring的返回来值
android hooking watch class_method java.lang.StringBuilder.toString --dump-return

//弹窗
android hooking watch class_method android.app.Dialog.show --dump-args --dump-backtrace --dump-return

//hook指定类, 会打印该类下的所有调用 
android hooking watch class com.xxx.xxx 

//设置返回值(只支持bool类型) 
android hooking set return_value com.xxx.xxx.methodName false

8. 关闭app的ssl校验

android sslpinning disable

9. Spawn方式Hook
   从Objection的使用操作中我们可以发现，Obejction采用Attach附加模式进行Hook，这可能会让我们错过较早的Hook时机，可以通过如下的代码启动Objection，引号中的objection命令会在启动时就注入App。

objection -g packageName explore --startup-command 'android hooking watch xxx' 

ARIDA

管理PRC脚本，自动生成http接口的工具

1. 安装 下载

git clone git@github.com:lateautumn4lin/arida.git

使用conda安装

conda create -n arida python==3.8
conda install --yes --file requirements.txt

使用pip安装

virtualenv venv
source venv/bin/activate

// 下载pip安装格式的requirements.txt https://github.com/Boris-code/arida/blob/master/requirements.txt

pip install -r requirements.txt

2. 运行

uvicorn main:app --reload
watch 127.0.0.1:8000/docs

3. 开发

Config文件中写入自己的App信息
apps目录写开发相应的Frida-Js脚本，可参考其他两个文件
