Google Chrome prevents sites from launching Spectre-like attacks
If you're using Chrome, you now have fewer reasons to worry about Spectre-style security threats. Google has revealed that Chrome 67 for desktop and the matching Chrome OS release enable a previously experimental Site Isolation feature that reduces the chances of intruders using speculative execution side-channel attacks like Spectre. The technique limits the web renderer process to content from a single site, preventing an attacker's page from sharing malicious code through an innocent page (say, though cross-site pop-ups or remotely stored scripts). In theory, sinister types can't swipe passwords or other sensitive data while you're visiting otherwise innocuous sites.
