If you’re not running the latest version of Chrome (72.0.3626.121), you may be putting yourself at risk of attackers installing malware on your device or directing you to web pages that allow them to control your device remotely.
Chrome’s IT staff have identified a zero-day vulnerability in Chrome (see CVE-2019-5736 for all the technical background), which means that you should patch Chrome as soon as possible. To check if you’re up-to-date, open Chrome and go to the Settings page “About Chrome” by typing chrome://settings/help into the address bar. This will display your version number and automatically check for updates at the same time.
