Disassemble and Modify an Binary To Change a Function

In this gist I show how to disassemble and modify a Linux executable binary to change the body of a function. This will allow you to control how a binary behaves, even when you don't have access to the source code and you can't recompile it.

In my case, I was asked to try and bypass the protection mechanism implemented. The protection mechanism implemented was meant to only allow a binary to be run in presence of a valid license.

So basically my activity involved:

• Finding the function which performs the protection check
• Disassembling the binary

$VPN_NAME = 'VPN'
$ADDRESS = 'vpn.example.com'
$ACCOUNT = 'user1'

安装 docker

首先确定已经安装完成 docker，如果没有安装可以使用以下脚本快速安装并配置：

#!/system/xbin/bash
#Based on https://github.com/termux/termux-app/issues/77
export PREFIX='/data/data/com.termux/files/usr'
export HOME='/data/data/com.termux/files/home'
export LD_LIBRARY_PATH='/data/data/com.termux/files/usr/lib'

strongSwan setup for Road Warriors on macOS 10.12, iOS 10 and Windows 10

This setup is for remote users to connect into an office/home LAN using a VPN (ipsec). This is based on (but not the same as) the strongSwan documentation and this guide: https://raymii.org/s/tutorials/IPSEC_vpn_with_Ubuntu_16.04.html

I used strongSwan 5.5.1.

apt-get install -y strongswan strongswan-pki

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

chaos 的 qemu 技巧 （一） 网络桥接
http://ycool.com/post/sgeq9sf

原始的linux网络桥接 brctl 是很不错的技术，可以将虚拟机的网络和物理网络完好的桥接起来，
但是这个方法在服务器上应该是好的，然而，在桌面环境中，却会遇到一个大问题:
 桥接设备如br0 不能跟network manager之类良好兼容，而且桌面机更多时候会跑wifi，这个brctl就更苦了。
所以，经过详细研究，现整理出一套用parprouted + vdeswitch + dhcp-helper +qemu的解决方案。

本方案中，出了 vde_tunctl , parprouted , dhcp-helper几个命令必须有root权限，其他任何步骤不需要root权限，
而且，在虚拟机里面也不会看到发到host machine的数据，基本上来说，安全模型还是比较清晰的。
