Yesterday, I announced that your web browsers need to be update for a “zero-day” vulnerability (meaning it’s important). Hackers know about this vulnerability and are taking advantage right now. Here are the things you need to update right away, in addition to your web browsers.

Adobe
Read about and download the patch here to fix the zero-day vulnerability in Acrobat and Reader.
- Open Acrobat Reader, go to Help > Check for Updates and install now, or download the full Acrobat Reader installer.
- If you're using Acrobat Pro, you can launch Adobe Creative Cloud to find the update for that.

Google
Your Chrome browser should automatically check for updates and install them after a restart. The key here is that you need to quit Chrome completely, then relaunch it to apply the update. To make sure Chrome is up to date, click the three dots in the top right corner, then Help > About Google Chrome. Or, you can download a new copy of Google Chrome right here.

iOS for Apple iPhone and iPad
These devices need to be running the latest version of iOS 15.7.9 or iOS 16.6.1.
- Go to Settings > General > Software Update. Install now.

macOS for Apple computers
Apple also released security updates for its three latest operating systems, macOS Big Sur 11.7.10, macOS Monterey 12.6.9, and macOS Ventura 13.5.2. Any system older than these (not listed here) are no longer supported and should be upgraded. Reach out to me if you need help or guidance.
- In Big Sur and Monterey, click the Apple menu > System Preferences > Software Update. Install now.
- In Ventura, click the Apple menu > System Settings > General > Software Update. Install now.

Microsoft
The September 2023 Windows security update includes fixes for 59 known issues, like security bypasses and information disclosure vulnerabilities, and patches for two zero-day flaws.
- Go to Start > Settings > Windows Update > Check for updates. Install now.

Android
- Open Settings > System > System update.. Install now.
