Chances are you are using one of the four top web browsers to visit websites: Firefox, Chrome, Safari, and Edge. You need to update these browsers today (and any other browser you use), as patches were released to protect from a zero-day vulnerability that was discovered yesterday. As stated by Techmonitor, “As the flaws allow attackers to remotely run commands on targeted computers, this could lead to organizations experiencing data breaches or having their systems held for ransom.”

Instructions for updating each browser can be found in the links below. Let me know if you need help!
Google Chrome
Apple’s Safari
Mozilla Firefox
Microsoft Edge (for Windows)

The term "zero-day" refers to the fact that the vendor or developer has only just learned of the flaw – which means they have “zero days” to fix it. A zero-day attack takes place when hackers exploit the flaw before developers have a chance to address it.
