hwid | A HWID spoofer for Windows

INTRODUCTION

This thread should be the ending chapter for this first thread from 2014 and this second one from 2017.

To cut the story short, you simply need to know that the Microsoft Windows SDK includes a program called computerhardwareids.exe, which, as its name suggests, it generates (several) hardware identifiers for the computer, and I would like to replicate the CHID algorithm using .NET to generate the same identifiers as this program generates.

The list of CHIDS that this program can generate on Windows 10, which is the O.S that I'm using, is listed here:

1. HardwareID-0 Manufacturer + Family + Product Name + SKU Number + BIOS Vendor + BIOS Version + BIOS Major Release + BIOS Minor Release
2. HardwareID-1 Manufacturer + Family + Product Name + BIOS Vendor + BIOS Version + BIOS Major Release + BIOS Minor Release
3. HardwareID-2 Manufacturer + Product Name + BIOS Vendor + BIOS Version + BIOS Major Release + BIOS Minor Release
4. HardwareID-3 Manufacturer + Family + Product Name + SKU Number + Baseboard Manufacturer + Baseboard Product
5. HardwareID-4 Manufacturer + Family + Product Name + SKU Number
6. HardwareID-5 Manufacturer + Family + Product Name
7. HardwareID-6 Manufacturer + SKU Number + Baseboard Manufacturer + Baseboard Product
8. HardwareID-7 Manufacturer + SKU Number
9. HardwareID-8 Manufacturer + Product Name + Baseboard Manufacturer + Baseboard Product
10. HardwareID-9 Manufacturer + Product Name
11. HardwareID-10 Manufacturer + Family + Baseboard Manufacturer + Baseboard Product
12. HardwareID-11 Manufacturer + Family
13. HardwareID-12 Manufacturer + Enclosure Type
14. HardwareID-13 Manufacturer + Baseboard Manufacturer + Baseboard Product
15. HardwareID-14 Manufacturer

PROBLEM

I managed to replicate all hardware ids except: 0, 1, 2 and 12

I found that these four problematic identifiers have in common that they are the only which contains numeric values to append to the string with which to generate the UUID. See the table in this link or read this list:

• Name | Length | Type

• System BIOS Major Release | BYTE |Varies

• System BIOS Minor Release | BYTE | Varies

• Enclosure type | BYTE | Varies

I think this is a clear sign that I don't know how to treat those numerical values when building the string with which to generate the UUID.

QUESTION

I don't know in which WMI class to find the Enclosure Type value, but it doesn't matter because I really don't care about replicating the HardwareID-12 / Enclosure Type value, but I would like to be able replicate the HardwareID-0, HardwareID-1 and HardwareID-2

I already know from which WMI class to get the BIOS major and minor release version for HardwareID-0, HardwareID-1 and HardwareID-2, but the problem is that when I append those BIOS values to the string with which to generate the UUID, I end getting a totally different UUID from what computerhardwareids.exe generates.

My questions are:

• What I need to do to replicate the same exact generated UUID for HardwareID-0, HardwareID-1 and HardwareID-2?.

• Maybe I need to treat those numerical values in a special way, applying some format that I don't know when appending them to the string with which to generate the UUID?.

Please note that I DON'T have experience in reverse-engineering.

CODE

This is the code I'm using, written in VB.NET. At its current state I consider it a working solution that replicates (or it should replicate) the same computer hardware ids as computerhardwareids.exe program generate, except hardware ids 0, 1, 2 and 12 for the reasons that I have explained.

I am connecting a "Janitza UMG96RM-E" device to a Windows Laptop where I am using Hyper-V to use Linux cmds. I registered the Laptop as an Edge device and added Modbus to the set of modules. I read the Janitza documentation (start Address, nbre of bits ...) and I Added the correct Ip Address the Module Twins file... Everything looks heathy except I am not receiving any data from the Modbus module... I am not able to figure out what is wrong ? Here is some logs from edgeHub module. ...

After integrating the IAP in Unity Project, IAP is not initializing in the Repack APK but it is working in UDP APK.

I have used 2.2.2 version Unity Distribution Portal package for In App Purchase. While testing the app in UDP apk, it seems working well. After that, when we upload that apk to Unity dashboard for Repack, the IAP is not initializing(Means can able to see the welcome xxxx, after that nothing happened.)

The below code shows the clear picture.

I already got Health Kit Authorization, but whenever i run the sign in method i keep getting error code 8002 which is not documented, and when i run authorizations or whenever i try to read any data with health kit for example heart rate i keep getting result Code 4 which means the communication with Health App was interrupted.

How can i solve this.

I'm providing code and Logcat

Our security team found insecure functions that exist in Push Kit libraries and would like to know whether it would be fixed in upcoming versions or it will stay and we have to accept the risk or if there is any customization can be done to overcome the security concerns:

Improper Verification of Intent (CWE-925), App Permissions (MSTG-PLATFORM-1)

we are using the below sdk version:

implementation 'com.huawei.hms:hwid:5.0.1.300'

implementation 'com.huawei.hms:push:5.0.2.300'

and below are the details:

Service: com.huawei.hms.support.api.push.service.HmsMsgService

the service in the SDK manifest file exists as below:

In foreground i can read data message, but in background message was lost!

I have read this tutorial : Receiving Data Messages When the App Is in Background or Killed State

In the tutorial the function for run in background the data listener is

HmsPushMessaging.setBackgroundMessageHandler

But not seem working
