Frida Hook 基础教学文档<\/h1>

一、Frida 安装与配置<\/h2>

1.1 环境要求<\/h3>

Python环境<\/strong>：需要Python3环境<\/li>
设备要求<\/strong>：Android设备需要ROOT权限<\/li>

工具版本<\/strong>：推荐使用Frida 16.1.10版本（其他版本可能报错）<\/li> <\/ul>
1.2 服务端安装（PC端）<\/h3>
执行以下命令安装Frida和Frida-tools：<\/p>
pip install frida==<\/span>16.1.10 -i https:\/\/pypi.tuna.tsinghua.edu.cn\/simple <\/span><\/span>pip install frida-tools==<\/span>12.1.3 -i https:\/\/pypi.tuna.tsinghua.edu.cn\/simple <\/span><\/span><\/code><\/pre>1.3 客户端安装（Android端）<\/h3> 确定设备CPU架构：<\/li> <\/ol> adb root <\/span><\/span>getprop ro.product.cpu.abi <\/span><\/span><\/code><\/pre> 根据架构从官网下载对应版本的frida-server<\/li> 推送frida-server到设备：<\/li> <\/ol> adb push frida-server-16.1.0-android-x86_64.xz \/storage\/emulated\/0\/ <\/span><\/span><\/code><\/pre> 解压并添加执行权限：<\/li> <\/ol> unxz frida-server-16.1.0-android-x86_64.xz <\/span><\/span>chmod +x frida-server-16.1.0-android-x86_64 <\/span><\/span><\/code><\/pre>二、Frida 基本使用<\/h2> 2.1 启动Frida服务<\/h3> 在设备上运行frida-server<\/li> 端口转发：<\/li> <\/ol> adb forward tcp:27042 tcp:27042 <\/span><\/span><\/code><\/pre> 列出设备进程：<\/li> <\/ol> frida-ps -U <\/span><\/span><\/code><\/pre>三、HOOK 基础操作<\/h2> 3.1 准备工作<\/h3> 获取目标APK并反编译<\/li> 分析代码，确定需要Hook的关键点<\/li> <\/ol> 3.2 编写Hook脚本示例<\/h3> Java<\/span>.perform<\/span>(function<\/span> () { <\/span><\/span> let<\/span> k<\/span> =<\/span> Java<\/span>.use<\/span>("com.baidu.shucheng91.download.k"<\/span>); <\/span><\/span> k<\/span>["b"<\/span>].overload<\/span>('java.lang.String'<\/span>, 'java.util.Map'<\/span>).implementation<\/span> =<\/span> function<\/span> (str<\/span>, map<\/span>) { <\/span><\/span> console<\/span>.log<\/span>(`k.b is called: str=<\/span>${<\/span>str<\/span>}<\/span>, map=<\/span>${<\/span>map<\/span>}<\/span>`<\/span>); <\/span><\/span> let<\/span> result<\/span> =<\/span> this<\/span>["b"<\/span>](str<\/span>, map<\/span>); <\/span><\/span> console<\/span>.log<\/span>(`k.b result=<\/span>${<\/span>result<\/span>}<\/span>`<\/span>); <\/span><\/span> return<\/span> result<\/span>; <\/span><\/span> }; <\/span><\/span>}); <\/span><\/span><\/code><\/pre>3.3 执行Hook<\/h3> frida -U -f "com.nd.android.pandareader"<\/span> -l "xxxx01.js"<\/span> <\/span><\/span><\/code><\/pre>四、HOOK 概念<\/h2> HOOK技术是指在程序中插入代码块进行调试，能够：<\/p> 监控和调试程序的行为<\/li> 修改程序的某些动作<\/li> 获取程序运行时的关键数据<\/li> <\/ul> 五、注意事项<\/h2> 确保设备已ROOT<\/li> 使用推荐的Frida版本以避免兼容性问题<\/li> 注意frida-server的架构与设备匹配<\/li> 确保adb连接正常<\/li> 分析目标APK时，需要准确找到关键类和方法<\/li> <\/ol> 六、进阶方向<\/h2> 动态修改函数返回值<\/li> 拦截和修改网络请求<\/li> 绕过SSL Pinning<\/li> 内存操作和Native层Hook<\/li> 反反调试技术<\/li> <\/ol> 通过以上步骤，您可以完成基本的APP Hook操作，为进一步的逆向分析和安全研究打下基础。<\/p>
