Security flaw found in Microsoft Edge browser

19h agoVia MicrosoftWritten for Lucame clients

Microsoft has disclosed a spoofing vulnerability in its Edge browser, which is built on the Chromium engine. A spoofing vulnerability means an attacker could make something appear to come from a trusted source when it doesn't. Details are limited at this stage, but Microsoft has logged it formally and a fix is expected. Edge is widely used across business environments, so it's worth keeping an eye on this one.

What this means for your business

If your staff use Edge as their day-to-day browser, you'll want to make sure it's kept up to date as Microsoft releases patches. Most managed devices will pick these up automatically, but it's worth confirming that auto-updates are switched on. If you're unsure, get in touch and we can check your setup.
