Add hackback.txt which is a tutor from a hacker who cracked Gamma Group
Internationa.

一周前，有黑客入侵了受争议的英国间谍软件公司Gamma Group
International内网，公开了40GB的内部文档和恶意程序源代码（BT种子）。现在，这位匿名黑客公布了一个DIY指南，教你如何入侵目标的网络。指南发布在pastebin上，作者称准黑客首先需要做好安全准备，用加密软件Truecrypt
7.1a制作一个隐藏的加密卷，在这个加密卷内安装Whonix，不要使用与你名字和地址相关联的网络接入，所有的行动都在加密卷内进行。作者也强调，入侵是非法的。

It seems alias 'set' for set-option doesn't work.
