(Android) 如何使用HOOK实现动态注入以及自动化操作
为什么会有这边博文?
最近一直在搞一些apk破解以及自动化方面的东西.觉得有必要记录一下.也是为了修改下自己懒的毛病(很久很久很久没更新博客了)
一. 项目需求
项目功能:
本文将使用QQ为例,利用Hook实现自动登录,自动退出登录功能
项目流程:
流程比较简单
二. 资源准备
大致需要准备以下东西:
- 一台空闲的安卓手机,能root最好.
- 安装VirtualXposed(传送门),安装QQ(传送门,提取码: ty58)(注意QQ是8.0.0.4000版本,不同版本可能会影响hook点),对于不懂怎么使用hook的请参考
- 将QQ安装到VirtualXposed
- QQ脱壳获取源代码(不懂脱壳操作请点这里)
三. 功能实现
3.1 实现自动从QQ新用户页跳转到登陆页
第一次启动qq的时候,qq会停留在,显然要实现登陆的话我们需要让其自动进入登陆页面,如图:
登陆图片.png
3.1.1 获取新用户页的堆栈信息(手机需要连接电脑)
adb shell dumpsys activity >>输出路径
下面是导出的堆栈信息:
堆栈信息.png
我们可以得到登陆界面的RegisterGuideView.以及登陆按钮的16进制值7f0b0da9
3.1.2 获取登陆按钮逻辑的Hook点
通过PowerGREP工具对脱壳后的QQdex源码(脱壳后可得到十几个dex文件)进行字符串搜索找到RegisterGuideView所在的dex,然后通过jeb工具反编译该dex, 以下是RegisterGuideView类的源码
package com.tencent.mobileqq.activity.registerGuideLogin;
import android.annotation.SuppressLint;
import android.content.Intent;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View$OnClickListener;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
import com.tencent.mobileqq.activity.RegisterPhoneNumActivity;
import com.tencent.mobileqq.app.QQAppInterface;
import com.tencent.mobileqq.statistics.ReportController;
import com.tencent.qphone.base.util.QLog;
public class RegisterGuideView extends GuideBaseFragment implements View$OnClickListener {
private View a;
private Button a;
private Button b;
public RegisterGuideView() {
super();
}
@SuppressLint(value={"ValidFragment"}) public RegisterGuideView(QQAppInterface arg1) {
super(arg1);
}
public void onClick(View arg14) {
Intent v0;
switch(arg14.getId()) {
case 2131430824: {
ReportController.b(this.a, "CliOper", "", "", "0X8007576", "0X8007576", 0, 0, "", "", "", "");
v0 = new Intent(this.a, RegisterPhoneNumActivity.class);
v0.putExtra("key_register_from", 2);
v0.putExtra("leftViewText", this.a.getString(2131499116));
v0.addFlags(67108864);
this.a.startActivity(v0);
break;
}
case 2131430825: {
ReportController.b(this.a, "CliOper", "", "", "0X8007575", "0X8007575", 0, 0, "", "", "", "");
v0 = this.a.getIntent();
v0.putExtra("from_register_guide", true);
v0.putExtra("is_need_show_logo_animation", true);
GuideBaseFragment v0_1 = GuideHandler.a(this.a, this.a);
if(this.a == null) {
return;
}
this.a.a(v0_1);
break;
}
}
}
public View onCreateView(LayoutInflater arg7, ViewGroup arg8, Bundle arg9) {
View v1 = arg7.inflate(2130903607, arg8, false);
this.a = v1.findViewById(2131428759);
this.a.setVisibility(0);
this.a = v1.findViewById(2131430825);
this.b = v1.findViewById(2131430824);
this.a.setOnClickListener(((View$OnClickListener)this));
this.b.setOnClickListener(((View$OnClickListener)this));
View v0 = v1.findViewById(2131430823);
try {
((ImageView)v0).setImageDrawable(new BitmapDrawable(this.getResources(), this.getActivity().getAssets().open("splash.jpg")));
}
catch(Throwable v0_1) {
QLog.e("LoginActivity.RegisterGuideView", 1, "onCreateView error:" + v0_1.getMessage());
}
return v1;
}
}
通过我们得到的登陆按钮的16进制值7f0b0da9可以确定10进制值2131430825,从而确定变量a是登陆按钮.
3.1.3 通过Hook 实现登陆按钮点击
由于我们已经找到了登陆按钮相关的类和按钮变量对象,接下来我们只需要通过hook拿到该按钮对象,实现点击即可自动进入登陆页面
以下是核心代码:
/**
* hook新用户页,拿到登陆按钮,模拟点击登陆
*/
public static void hookRegisterGuideLogin()
{
XposedHelpers.findAndHookMethod("com.tencent.mobileqq.activity.registerGuideLogin.RegisterGuideView", context.getClassLoader(), "onCreateView", LayoutInflater.class, ViewGroup.class, Bundle.class, new XC_MethodHook()
{
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable
{
super.afterHookedMethod(param);
final Object obj = param.thisObject;
doMainLooper(context, 1000, new Runnable()
{
@Override
public void run()
{
//得到按钮对象
Object viewObj = ReflectUtils.getFieldValueForFiledClsNm(obj, "a", "android.widget.Button");
if (viewObj instanceof Button)
{
//点击按钮
((Button) viewObj).performClick();
}
}
});
}
});
}
目前为止,我们就已经完成了长征的第一步,从新用户页自动点击到登陆页. 下面是成果演示:
前往登陆界面.gif
可以看到我们已经实现了从新用户页点击到登陆页了.
3.2 实现登陆页自动填充登陆账号和密码并自动登陆
3.2.1 打印登陆页的堆栈信息
如下图,我们可以找到登陆页面所在的类名,以及按钮输入框等信息
登陆图片-1.png
3.2.2 找到源码中登陆相关hook点
LoginView的重要源码如下,我们基本可以定位到账号输入框,密码输入框,登陆按钮等对象

3.2.3 使用hook实现自动登陆
以下是核心代码
private static void hookAutoLogin()
{
String loginviewClsNm = "com.tencent.mobileqq.activity.registerGuideLogin.LoginView";
final String loginBtnClsNm = "com.tencent.mobileqq.activity.registerGuideLogin.LoginAnimBtnView"; //登陆按钮类名
final String loginBtnFiledNm = "a"; //登陆按钮变量名
final String pwdEdTextClsNm = "com.tencent.mobileqq.widget.CustomSafeEditText"; //密码输入框类名
final String pwdEdTextFiledNm = "a"; //密码输入框变量名
final String newStyleDropdownViewClsNm = "com.tencent.mobileqq.widget.NewStyleDropdownView"; //输入框外view类名
final String newStyleDropdownViewFiledNm = "a"; //输入框外view类名
final String actInputViewClsNm = "aqsw"; //输入框类名
final String actInputViewFiledNm = "a"; //输入框的变量名
//hook登录页节点
XposedHelpers.findAndHookMethod(loginviewClsNm, context.getClassLoader(), "a", View.class, new XC_MethodHook()
{
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable
{
super.afterHookedMethod(param);
//得到登陆所需对象
Object loginViewObj = param.thisObject;
Object newStyleDropdownViewOBj = ReflectUtils.getFieldValueForFiledClsNm(loginViewObj, newStyleDropdownViewFiledNm, newStyleDropdownViewClsNm);
final Object loginBtnObj = ReflectUtils.getFieldValueForFiledClsNm(loginViewObj, loginBtnFiledNm, loginBtnClsNm);
final Object pwdEdTextObj = ReflectUtils.getFieldValueForFiledClsNm(loginViewObj, pwdEdTextFiledNm, pwdEdTextClsNm);
final Object actInputViewobj = ReflectUtils.getFieldValueForFiledClsNm(newStyleDropdownViewOBj, actInputViewFiledNm, actInputViewClsNm);
// 开始输入账号密码登陆
final String account="";
final String pwd="";
doMainLooper(context, 3000, new Runnable()
{
@Override
public void run()
{
if (actInputViewobj instanceof AutoCompleteTextView)
{
((AutoCompleteTextView) actInputViewobj).setText(account);
}
if (pwdEdTextObj instanceof EditText)
{
((EditText) pwdEdTextObj).setText(pwd);
}
if (loginBtnObj instanceof View)
{
((View) loginBtnObj).performClick();
}
}
});
}
});
}
至此我们的自动登陆功能就算是做好了,下面是演示:
自动登陆.gif
3.3 实现退出登录
和上面步骤一样,我们需要从账号管理界面界面入手
账号管理.png
3.3.1 获取堆栈信息
拿到堆栈信息如下,找到所在的类AccountManageActivity
账号管理堆栈信息.png
3.3.2 查找源码中退出登录的相关hook点
public void a(int arg11, boolean arg12) {
String v9 = null;
int v5 = 7000;
int v6 = 2;
Object v0 = this.a.get(arg11);
if(v0 == null) {
this.a.dismiss();
if(QLog.isColorLevel()) {
QLog.w("Switch_Account", v6, "onItemLongClick simple account = null");
}
}
else {
String v2 = ((SimpleAccount)v0).getUin();
String v3 = this.app.getCurrentAccountUin();
this.a = v2;
if(v2.equals(v3)) {
AccountManageActivity.a(((Activity)this), this.app);
}
if(QLog.isColorLevel()) {
QLog.d("hunter", v6, "++++++++++");
}
this.a(this.a, arg12);
HistoryChatMsgSearchKeyUtil.a(v2);
CrmUtils.a(this.getBaseContext(), v3);
this.a.remove(v0);
Manager v1 = this.app.getManager(60);
if(v1 != null && (((SubAccountManager)v1).a(v2))) {
SubAccountControll.a(this.app, 0, v2);
((SubAccountManager)v1).e(v2);
((SubAccountManager)v1).a(v2, v9, true);
((SubAccountManager)v1).a(v2, v6);
SubAccountControll.a(this.app, v2, 7);
int v1_1 = 1 - this.app.a().a(v2, v5);
if(v1_1 != 0) {
this.app.a().c(v2, v5, v1_1);
}
if(!QLog.isColorLevel()) {
goto label_68;
}
QLog.d("SUB_ACCOUNT", v6, "deleteAccount() hint need to verify,msg num=1, subUin=" + v2);
}
label_68:
GesturePWDUtils.clearGestureData(this.getActivity(), ((SimpleAccount)v0).getUin());
if(v2.equals(v3)) {
this.app.getApplication().refreAccountList();
List v0_1 = this.getAppRuntime().getApplication().getAllAccounts();
if(v0_1 != null && v0_1.size() > 0) {
v0 = v0_1.get(0);
if(((SimpleAccount)v0).isLogined()) {
this.getAppRuntime().startPCActivePolling(((SimpleAccount)v0).getUin(), "delAccount");
}
}
}
ThreadManager.post(new unx(this, v2, arg12, arg11), 8, ((ThreadExcutor$IThreadListener)v9), true);
}
}
3.3.3 hook注入退出方法,实现自动退出登录
以下是核心代码:
private static void loginOut()
{
//hook 账号管理页
XposedHelpers.findAndHookMethod(accountManageActivityClsNm, context.getClassLoader(), "a", Bundle.class, new XC_MethodHook()
{
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable
{
super.afterHookedMethod(param);
final Object accountManageActivityObj = param.thisObject;
doMainLooper(context, 3000, new Runnable()
{
@Override
public void run()
{
ReflectUtils.invokeMethod(accountManageActivityObj, "a", new Class[]{int.class, boolean.class}, 0, true);
}
});
}
});
}
四. 最终效果
已经实现了完全的自动登录,自动退出登录操作,完整展示:
退出登录.gif
由于篇幅原因,部分代码已省略,完整代码已上传github(传送门)
实际上,利用hook动态注入可以无所不能,大家可以发挥想象.(不过希望用在正途哦,手动滑稽)
