frida https抓包

本文介绍: web端一般带入证书、https代理即可解决大部分需求，但是，有些app需要处理ssl pinning验证。frida处理ssl pin的步骤大体如下。当然，除了上述步骤，可能还需要：导入根证书，设置代理等。的版本号必须要一致，否则会提示错误。

web端导入证书、https代理即可解决大部分需求，但是，有些app需要处理ssl pinning验证。

废话不多说。frida处理ssl pin的步骤大体如下。

安装python3.x,并在python环境中安装frida：

pip install frida
pip install frida-tools

在这里插入图片描述

下载frida-server，并使用adb命令push到/data/local/tmp目录下,并运行：

adb push frida-server /data/local/tmp

chmod 777 ./frida-server

./frida-server

注意：此处的

和

的版本号必须要一致，否则会提示如下错误：

color{red}注意：此处的frida-server和frida的版本号必须要一致，否则会提示如下错误：

执行如下命令，即可hook并绕过app对ssl pin的检测：

frida -U -f packagename -l ./ssl.js --no-pause

当然，除了上述步骤，可能还需要：导入根证书，设置代理等。

可能会用的命令：

显示cpu信息：

cat /proc/cupinfo

adb shell getprop ro.product.cpu.abi

查看frida可以ssl pin的进程：

frida-ps -U

tcpdump命令抓包：

tcpdump -i wlan0 -s 0 -w /sdcard/test.pcap
