As announced by Google engineer and "usable security researcher" Adrienne Porter Felt on Twitter, the newest designs for
malware and phishing site warnings from Google Chrome have gone out on the Canary and Dev channels.
Google Safe Browsing is a service that maintains blacklists of URLs of sits that contain phishing and malware. It provides an API for other software to use, and is used by both Apple Safari and Mozilla Firefox. Microsoft uses their own
SmartScreen service.
