PHP Forged HTTP header hack anti-theft chain _php Tutorial

< span="">Anti-theft chain< span="">

Forged Referer instance code, mainly used for some breakthrough anti-theft chain, than tablets, software and so on.

Here directly to the complete program, the specific application can be modified by themselves.
The example I gave here is very simple, and in fact, there are many applications that can be developed from this example. such as hiding the real URL address ... Hey, I'm going to do the exact analysis.
Create a new file file.php here. The next parameter is the target address of the referfer that needs to be forged. such as: File.php/http://www.xxx.xxx/xxx.mp3

Code:

4. $url = Str_replace ('/file.php/',',$_server[" Request_uri "]); //Get the URL that needs to be converted. Here I am lazy, do not do safety testing, need to add their own to
6. $downfile = Str_replace ("","%20",$url); //Replace spaces, etc., can be replaced according to the actual situation
8. $downfile = Str_replace ("http://","",$downfile);//Remove HTTP///
10. $urlarr = Explode ("/",$downfile); //Break out Domain name with "/"
12. $domain = $urlarr [0]; //Domain name
14. $getfile = Str_replace ($urlarr[0],",$downfile); //Get part of the header
16. $content = @ Fsockopen ("$domain", $errno , $errstr,); //Connect to target host
18. if (! $content ) {//Link not on prompt error
20. die ("Sorry, unable to connect on $domain. ");
22. }
24. fputs ($content, "GET $getfile http/1.0rn");
26. fputs ($content, "Host: $domainrn");
28. fputs ($content, "Referer: $domainrn"); //Forged parts
30. fputs ($content, "user-agent:mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) rnrn ");
32. while (! feof ($content)) {
34. $TP .= fgets ($content, +);
36. if (strstr($tp,"OK"){ //here to illustrate. The first line of the header is typically the state of the requested file. Please refer to the HTTP 1.1 status code and its meaning hi.baidu.com/110911/blog/item/21f20d2475af812ed50742c5.html here is the normal file request status, just a direct turn on it. Continuation program for other states
38. Header ("Location: $url");
40. die ();
42. }
44. }
46. //302 steering, most of the anti-theft chain system is the first to judge the Referfer, the words then turn to the real address. Here's how to get the real address.
48. $arr = Explode ("n",$tp);
50. $arr 1 = Explode ("Location:",$tp); //Break out the real-time address behind the location
52. $arr 2 = Explode ("n",$arr 1[1]);
54. Header (' content-type:application/force-download '); //Mandatory Download
56. Header ("Location:". ) $arr 2 [0]); //Turn to Destination address
58. die ();
60. ?>

The above code only for the use of Referer to determine whether hotlinking anti-theft chain system, the use of other special methods of anti-theft chain, it does not apply.

4. $txt = $_get [' url '];
6. Echo referfile ($txt,' http://www.jbxue.com/');
12. function referfile ($url,$refer=") {
14. $opt = Array ('http '= =array(' header '= "Referer: $refer" ));
16. $context =stream_context_create ($opt);
18. Header ("Location:". ) $url );
20. return file_get_contents($url, False,$context);
22. }
26. $host = "Pakey.net" ; //The domain you want to visit
28. $target = "/test.asp" ; //The page address you want to visit
30. $referer = "http//uuwar.com/" ;//Forge the antecedents page
32. $fp = Fsockopen ($host, $errno , $errstr,);
34. if (! $fp ){
36. Echo "$errstr ($errno)
    \ n ";
38. }Else{
40. $out = "
42. GET $target http/1.1
44. Host: $host
46. Referer: $referer
48. Connection:close\r\n\r\n ";
54. Fwrite ($fp, $out);
56. while (! feof ($fp)) {
58. Echo fgets($fp, 1024x768);
60. }
62. Fclose ($fp);
64. }
66. ?>
