反彈shell集錦

popen 建立 它的 socket pan \n edi -c file

1. 關於反彈shell

就是控制端監聽在某TCP/UDP端口,被控端發起請求到該端口,並將其命令行的輸入輸出轉到控制端。reverse shell與telnet,ssh等標準shell對應,本質上是網絡概念的客戶端與服務端的角色反轉。

2. 反彈shell的原因

通常用於被控端因防火墻受限、權限不足、端口被占用等情形

假設我們攻擊了一臺機器,打開了該機器的一個端口,攻擊者在自己的機器去連接目標機器(目標ip:目標機器端口),這是比較常規的形式,我們叫做正向連接。遠程桌面,web服務,ssh,telnet等等,都是正向連接。那麽什麽情況下正向連接不太好用了呢?

1)某客戶機中了你的網馬,但是它在局域網內,你直接連接不了。

2)它的ip會動態改變,你不能持續控制。

3)由於防火墻等限制,對方機器只能發送請求,不能接收請求。

4)對於病毒,木馬,受害者什麽時候能中招,對方的網絡環境是什麽樣的,什麽時候開關機,都是未知,所以建立一個服務端,讓惡意程序主動連接,才是上策。
