🚨 Critical WhatsApp Security Alert: Update Now to Stay Protected
Date: April 8, 2025Author: BYTEBAK Cybersecurity Team
How Often Do You Use WhatsApp?
Whether it's daily chats, quick phone calls, or sharing photos with friends and family, WhatsApp is part of our everyday lives. But even trusted platforms can face serious security issues — and a new one just surfaced.
On April 8, 2025, the Cyber Security Hub released an important update based on a Meta advisory that every WhatsApp user should pay attention to.
⚠️ What’s the Risk?
Meta has identified a spoofing vulnerability (CVE-2025-30401) in WhatsApp for Windows that could allow attackers to execute remote code on a victim’s device by sending specially crafted file attachments.
Here’s how the exploit works:
Attachments appear safe (e.g., a .jpg image), based on their MIME* type
But when opened, WhatsApp uses the file extension to decide how to handle it
A mismatch between these two can trick users into launching malicious code
This means a file that looks like an innocent image or document could actually be hiding a dangerous executable — and just clicking it could compromise your system.
✅ Who’s Affected?
All users running older versions of WhatsApp on Windows devices.
Meta has addressed the issue in version 2.2450.6. If you’re using any version prior to 2.2450.6, you need to update immediately.
🔧 How to Update WhatsApp for Windows
Open WhatsApp on your Windows device
Go to Settings → Help → Check for Updates
Make sure you’re on version 2.2450.6 or higher
If you're not sure — force the update. It's the safest choice.
