Android: Google security update dated Jan. 5 will include “mitigations” to help protect your phone, and future updates will include more fixes.
On Jan. 23, a new version of Google Chrome should also include mitigations to protect your desktop and phone from web-based attacks.
Google says an experimental feature called Site Isolation can help right away.
To turn on Site Isolation on Windows, Mac, Linux, Chrome OS or Android:
Type or copy-paste chrome://flags/#enable-site-per-process into the URL field at the top of your Chrome web browser, then hit the Enter key.
Look for Strict Site Isolation, then tap or click the box labeled Enable.
If your work is saved, hit Relaunch Now. Otherwise, save your work, then quit and relaunch Chrome.
For Chrome on iOS (iPhone, iPad), Google says Apple will deliver any necessary fixes.
Mozilla will update its current Firefox 57 and Microsoft will modify both its Internet Explorer and new Edge browsers.
Google’s Chromebooks are, or will be, automatically protected from these flaws, according to Google. The company says Chromebooks with ARM chips aren’t affected at all
Google says none of its other consumer-facing products (Google Home, Chromecast, WiFi, OnHub, Gmail, Apps and Services) are affected by these vulnerabilities.
Microsoft says it released a Win10 security update Wednesday to help mitigate the issue.
