Important Security Update for Adobe Acrobat and Reader Users

A recent security issue has been identified in Adobe Acrobat and Reader software, similar to finding a hidden door that could allow unwanted visitors into your home. If you're using outdated versions of these applications, your computer might be at risk of being compromised by malicious files that someone can trick you into opening.

Who is at Risk?

This vulnerability affects users who use the following versions of Adobe Acrobat and Reader:

  • Acrobat DC: 25.001.20672 and earlier (Windows and macOS)
  • Acrobat Reader DC: 25.001.20672 and earlier (Windows and macOS)
  • Acrobat 2024: 24.001.30254 and earlier (Windows and macOS)
  • Acrobat 2020: 20.005.30774 and earlier (Windows and macOS)

If you’re using any of these outdated versions, opening a malicious PDF file can allow hackers to run harmful code on your device, which is like a stranger sneaking into your home through that hidden door.

How to Stay Safe

Acting quickly is crucial to protect your computer from potential threats. Here’s what you need to do:

  1. Update Your Software: If you have Adobe Acrobat or Reader installed, you need to update to the latest version.
