What Gemini think about my Windows vulnerability

 https://zenodo.org/records/23062744

This document, titled "My World Wide vulnerability for Windows 2000/XP/7/8/10/11 and all Kind of Windows Servers 32bits/64bits", was written by Wadi Mami and published on December 7, 2021. It details a Denial of Service (DoS) attack vector leveraging the built-in Windows shutdown command.

Problem Description

  • Exploit Mechanism: The author highlights that if a batch script or executable triggering the shutdown -h command is placed into the Windows Startup folder, the operating system continually shuts down upon booting.
  • System Impact: This results in a full Denial of Service (DoS), preventing normal access to the machine until an administrator boots from external media (such as a USB drive or CD/DVD) to manually delete the startup script.
  • Code Examples Provided:
    • Batch Script (myvirus.bat): Uses an infinite loop construct (:loop ... goto loop) executing shutdown -h repeatedly.
    • VB.net Implementation: Demonstrates how high-level languages can achieve the same effect by recursively calling Process.Start("cmd", "/C shutdown -h").

Communication with Microsoft

  • Initial Reporting (2015): The author first reported the issue to the Microsoft Security Response Center (MSRC) in 2015. MSRC treated the proof-of-concept file as a malware detection issue rather than an OS-level vulnerability.
  • Submission Status (2022): On September 8, 2022, Microsoft updated Defender definition files to detect myvirus.bat as malware (Submission ID: e5de6000-5b28-4880-a96f-380a4fe9fb08).
  • Author's Critique: The author argues that treating the proof-of-concept as malware does not solve the root issue, as new scripts or compiled executables can easily bypass antivirus signatures.

Author's Proposed Solutions

  • Require password authentication or a mandatory confirmation prompt ("Yes/No") whenever the shutdown command is invoked.
  • Restrict or block execution of the shutdown command from Windows startup locations.
  • Restrict or limit repeated execution attempts of the shutdown command within the same user session.

Goldbach’s conjecture proven

In the name of God, the most gracious, the most merciful Thanks be to God, Lord of all worlds Peace and blessings be upon the noblest of messengers. Goldbach’s conjecture proven By me Wadï Mami Email : wmami@steg.com.tn / didipostman77@gmail.com Date : 30/10/2025   Goldbach's conjecture  is one of the oldest and best-known  unsolved problems  in  number theory  and all of  mathematics . It states that every  even   natural number  greater than 2 is the sum of two  prime numbers . ---------------------------------------------------------------------------------------------- A prime number must be an odd number except 2 The sum of 2 odd numbers is an even number Then The sum of two prime numbers is an even number except 2 (A). Erdös Theorem : For every integer n > 1, it exists always a prime number between n and 2n (Source : Le Beau livre des Maths De Pythagore à la 57 dimension DUNOD ed...

Résolution de la conjecture de Goldbach

  Résolution de la conjecture de Goldbach Auteur : Wadï Mami Date : October 30, 2025 Email : wmami@steg.com.tn / didipostman77@gmail.com Enoncé de la conjecture de Goldbach "Tout nombre pair supérieur à 2 est la somme de deux nombres premiers." Un nombre premier est un nombre impair, sauf 2. La somme de deux nombres impairs est un nombre pair. Alors La somme de deux nombres premiers est un nombre pair, sauf   pour 2. (A) Reste maintenant à démontrer l’autre sens pour la conjecture. En se basant sur le théorème d’Erdös qu’il a établi quand il avait 18 ans : Pour tout entier n > 1, il existe toujours un nombre premier entre n et 2n. Donc il existe Un nombre premier p entre n et 2n n <= p <= 2n      (I) et par analogie il existe un nombre premier q entre n/2 et n n/2<= q<= n       (II) (I)             +  ...
