Bypass test cookie slowAES protection with .Net C# [full code]

 Bypassing test cookie anti webscraping protection with c#

Hello friends, when I try to get the content of a web site, I've noticed that the content of page got from HttpWebRequest is not the same seen on the browser. The response of request was like :

<html>

<body>
    <script type="text/javascript" src="/aes.js"></script>
    <script>
        function toNumbers(d) {
            var e = [];
            d.replace(/(..)/g, function(d) {
                e.push(parseInt(d, 16))
            });
            return e
        }

        function toHex() {
            for (var d = [], d = 1 == arguments.length &&
            arguments[0].constructor == Array ? arguments[0] :
            arguments, e = "", f = 0; f < d.length; f++) e +=
            (16 > d[f] ? "0" : "") + d[f].toString(16);
            return e.toLowerCase()
        }
        var a = toNumbers("f655ba9d09a112d4968c63579db590b4"),
            b = toNumbers("98344c2eee86c3994890592585b49f80"),
            c = toNumbers("a76ce883a42eb6e9fff3e05d9cc6c7e5");
        document.cookie = "__test=" + toHex(slowAES.decrypt(c, 2, a, b)) +
        "; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/";
        location.href = "http://www.namazvakitleri.site/i=1";

This Javascript generates a unique cookie (based on client's IP address) and set it to client's cookies like 
: __test : e0b2e8876a97dbb86398701b67e3dc83 

and redirect client to the same adress with an extra argument (querystring) called i, for my situation, I see some other qs's like attemp etc.

on the second sequence, server checks the cookie exists, then redirect page you actually wanted.
this value is a MD5 generated value based client ip + somesecrettext;
MD5("192.168.0.1" + "keepmesecret") if you can get the same value from different browsers. Sometimes, some server admins can add the useragent info of browser.

There is a way to bypass it, by trying MD5 encryption with Hashcat, but it's hard way to go for me, another way is run this script like a javascript and get final cookie value.

First we have to obtain a,b,c vars in response :

           HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(
               "http://www.namazvakitleri.site/");
           myRequest.Method = "GET";
           HttpWebResponse myResponse;
           StreamReader sr;
           string result;
           myResponse = (HttpWebResponse)myRequest.GetResponse();
           sr = new StreamReader(myResponse.GetResponseStream(),
               System.Text.Encoding.UTF8);
           result = sr.ReadToEnd();
           string abc;
           int loc = result.IndexOf("var a=toNumbers(");
           string temp = result.Substring(loc, result.Length-loc);
           temp = temp.Replace("var a=toNumbers(\"""");
           loc = temp.IndexOf('"');
           a = temp.Substring(0,loc);
           temp = temp.Replace(a + "\"),b=toNumbers(\"""");
           loc = temp.IndexOf('"');
           b = temp.Substring(0, loc);
           temp = temp.Replace(b + "\"),c=toNumbers(\"""");
           loc = temp.IndexOf('"');
           c = temp.Substring(0, loc);
           textBox1.AppendText("a : " + a + "\r\n");
           textBox1.AppendText("b : " + b + "\r\n");
           textBox1.AppendText("c : " + c + "\r\n");
and we have a,b,c vars in string. In the script string hex variables converted into byte arrays, this function help us with it :

Conversion of string hex to byte array (c#)

byte[] toNumbers(string hex)
{
      return Enumerable.Range(0, hex.Length)
               .Where(x => x % 2 == 0)
               .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
               .ToArray();
}

convert all of them to byte arrays :

    byte[] anumbers = toNumbers(a);
    byte[] bnumbers = toNumbers(b);
    byte[] cnumbers = toNumbers(c);
ok, hex string values are in byte arrays now. 
Then we have to obtain slowAES.decrypt(c, 2, a, b) on C#, this returns byte array and we need to convert it into hex string back with this function :

Conversion of byte array to hex string (c#)

string toHex(byte[] inp)
        {
            string temp = BitConverter.ToString(inp);
            temp = temp.Replace("-""");
            return temp;
        }

Obtaining slowAES.decrypt(c,2,a,b) on C#

I try to get aes.js from page I tested by browsing : http://www.namazvakitleri.site/aes.js, you can also try to get yours, if yours is the same with mine, you are lucky, just copy class and use it. 

The content I seen is :

}


that's all just call that in your main code :

string finalcookie = (toHex(slowAES.decrypt(cnumbers, 2, anumbers, bnumbers))).ToLower();
and the second call by HttpWebRequest and successfully get the page you wanted:

myRequest = (HttpWebRequest)WebRequest.Create("http://www.namazvakitleri.site/?i=1");
           myRequest.Headers.Add("Cookie""__test=" + finalcookie);
           myResponse = (HttpWebResponse)myRequest.GetResponse();
           sr = new StreamReader(myResponse.GetResponseStream(), System.Text.Encoding.UTF8);
           result = sr.ReadToEnd();
           textBox1.AppendText(result + "\r\n");
notice that I added ?i=1 query string on the end of the address.
