The Pakistan Telecommunication Authority (PTA) has issued a critical cybersecurity advisory that every Microsoft Office user in Pakistan should take seriously. 🧑💻 Whether you’re using Microsoft 365, Office 2019, or SharePoint Server — your system could be vulnerable to dangerous new security flaws.
Let’s break down what you need to know — and what you can do right now to stay safe.
⚠️ What’s the Threat?
PTA’s advisory highlights multiple high-severity vulnerabilities in widely used Microsoft products, including:
- Microsoft 365 Apps for Enterprise
