Microsoft Edge has a spoofing flaw you should patch now

19h agoVia MicrosoftWritten for Lucame clients

Microsoft has disclosed a vulnerability in its Edge browser that lets an attacker on a network trick users into seeing fake or manipulated content within the browser window. The flaw comes down to how Edge handles layered page elements, which can be abused to make a malicious page look like a legitimate one. It's the kind of weakness that gets used in phishing or credential-harvesting attacks, where the goal is to get someone to type in a password or click something they otherwise wouldn't.

What this means for your business

If your staff use Edge as their day-to-day browser, and most Windows users do by default, you'll want to make sure it's updated as soon as the patch is available. Edge updates itself automatically in most setups, but it's worth checking that auto-update hasn't been turned off, particularly on any machines that don't restart often. If you're unsure, get your IT team to verify Edge is on the latest version across your fleet.
