Hi, this is just something someone wanted me to make for them a while back, I want to contribute to the community so I decided to share this.

Note: I got some of the code from online, but I can't remember where I got it from, but, credits to whoever wrote it.

Oh, btw, remember to import System.Management (using System.Management;) to be able to use the code shown below

Code

public string GetHDDSerial() // Public string that contains the variable of the hardware id string from URL.txt
       {
           ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
           foreach (ManagementObject wmi_HD in searcher.Get())
           {
               if (wmi_HD["SerialNumber"] != null)
                   return wmi_HD["SerialNumber"].ToString();
           }

           return string.Empty;
       }

     
       private void lgnhwid_Click(object sender, EventArgs e)
       {

           System.Net.WebClient Wc = new System.Net.WebClient();
           string pplbanned = Wc.DownloadString("Web URL"); // Banned Hardware ID's from server
           string pplallowed = Wc.DownloadString("Web URL"); // Whitelisted Hardware ID's from server

           if (pplbanned.Contains(GetHDDSerial())) // this if statement checks if the System Hardware ID matches with the string from the server
           {
               MessageBox.Show("You have been banned from '[name]'!", Text, MessageBoxButtons.OK, MessageBoxIcon.Error);
               Environment.Exit(-1);
           }
           else if (pplallowed.Contains(GetHDDSerial()))
           {
               MessageBox.Show("You're allowed to use '[name]', Welcome.", Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
               HWDI_Login frm = new HWDI_Login();
               frm.Show();
               this.Hide();
           }
           else
           {
               MessageBox.Show("You're not whitelisted, make sure you sent Your" +
                   " Hwid to [name] and you bought our [product].", Text, MessageBoxButtons.OK, MessageBoxIcon.Warning);
               Environment.Exit(-1);
           }
           
       }

       private void HWDI_Login_Load(object sender, EventArgs e)
       {
           var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor");  // Get System Hardware id
           ManagementObjectCollection mbsList = mbs.Get();
           string id = "";
           foreach (ManagementObject mo in mbsList)
           {
               id = mo["ProcessorId"].ToString();
               break;
           }

           System_HWDI.Text = "System Hardware ID: " + id;
       }

This will be easily bypassed. You should atleast make it encrypted, do more "server-sided" checks.

Anything coming from the server and going to the server can be spoofed if it is static.

Hey, thanks for the contribution!

Just a tiny improvement (since I'm a nitpicker):

Instead of querying all properties from the PhysicalMedia WMI class:

Code

"SELECT * FROM Win32_PhysicalMedia"

You should simply just query the property you need:

Code

"SELECT SerialNumber FROM Win32_PhysicalMedia"

Not even using SSL again, which is one thing lots of people forget here.

Here’s another unique identifier that Microsoft uses in conjunction with your windows serial code https://pastebin.com/1bSdXFYP

Ah, wow, didn't even know you could do that, thanks!

Ah, I'm sorry to disappoint.

Overall this good to a point, thanks for contribution.

try checking your on stuff by using fiddler, you can isolate and read the packets.
also, make sure your useing something like dotfuscator, i use smart assembly
this kinda thing takes alot to get it working as safe as you can, make sure reflector cant just pull your code
C# usually boils down to security through obscurity.
Not that i know anything lol 🤫

Sorry for being rude but I can bypass this by returning true data with a debugger...

Perhaps stop grave-digging? Yeah, We get it. It can be bypassed with a debugger. So can a lot of things. HWID is only 1 layer of protection. Anyone who solely relies on these dated methods probably doesn't even have anything worth protecting.
