hook框架frida的安裝以及簡單實用案例

1.下載地址

https://github.co/frida/frida/releases

2.另外兩種安裝方法

1.Install from prebuilt binaries

This is the recommended way to get started. All you need to do is:

pip install frida-tools # CLI tools
pip install frida       # Python bindings
npm install frida       # Node.js bindings

You may also download pre-built binaries for various operating systems from Frida's releases page on GitHub.

2.Build your own binaries

Dependencies

For running the Frida CLI tools, i.e. frida, frida-ls-devices, frida-ps, frida-kill, frida-trace, and frida-discover, you need Python plus a few packages:

pip3 install colorama prompt-toolkit pygments

Linux

make

macOS and iOS

First make a trusted code-signing certificate. You can use the guide at https://sourceware.org/gdb/wiki/PermissionsDarwin in the sections "Create a certificate in the System Keychain" and "Trust the certificate for code signing". You can use the name frida-cert instead of gdb-cert if you'd like.

Next export the name of the created certificate to the environment variables MAC_CERTID and IOS_CERTID, and run make:

export MAC_CERTID=frida-cert
export IOS_CERTID=frida-cert
make

To ensure that macOS accepts the newly created certificate, restart the taskgated daemon:

sudo killall taskgated

Windows

frida.sln

(Requires Visual Studio 2017.)

3.簡單實用

獲得android手機當前最前端Activity所在的進程

get_front_app.py

其中get_front_app.py的內容以下：

import frida
rdev = frida.get_remote_device()
front_app = rdev.get_frontmost_application()
print front_app
12341234

枚舉android手機全部的進程

enum_process.py

enum_process.py內容以下：

import frida
rdev = frida.get_remote_device()
processes = rdev.enumerate_processes()
for process in processes:
    print process
1234512345

枚舉某個進程加載的全部模塊以及模塊中的導出函數

import frida
rdev = frida.get_remote_device()
session = rdev.attach("com.tencent.mm")  #若是存在兩個同樣的進程名能夠採用rdev.attach(pid)的方式
modules = session.enumerate_modules()
for module in modules:
    print module
    export_funcs = module.enumerate_exports()
    print "\tfunc_name\tRVA"
    for export_func in export_funcs:
        print "\t%s\t%s"%(export_func.name,hex(export_func.relative_address))

hook android的java層函數

以下代碼爲hook微信（測試版本爲6.3.13，不一樣版本因爲混淆名字的隨機生成的緣由或者代碼改動致使類名不同）
com.tencent.mm.sdk.platformtools.ay類的隨機數生成函數，讓微信猜拳隨機（type=2），而搖色子老是爲6點（type=5）

import frida
import sys
rdev = frida.get_remote_device()
session = rdev.attach("com.tencent.mm")

scr = """
Java.perform(function () {
var ay = Java.use("com.tencent.mm.sdk.platformtools.ay");
ay.pu.implementation = function(){
    var type = arguments[0];
    send("type="+type);
    if (type == 2)
    {
    return this.pu(type);
    }
    else
    {
    return 5;
    }
};

});
"""

script = session.create_script(scr)
def on_message(message ,data):
    print message
script.on("message" , on_message)
script.load()

經過注入拋出異常代碼實現跟蹤程序調用棧

在< >這本書中第八章有介紹經過重打包寫入異常代碼進行棧跟蹤，可是這樣比較麻煩，使用frida注入更方便。
