Google Safe Browsing
|Operating system||Android, Chrome OS, Windows, macOS, iOS, Web browsers|
Google Safe Browsing is a blacklist service provided by Google that provides lists of URLs for web resources that contain malware or phishing content. The Google Chrome, Safari, Firefox, Vivaldi, and GNOME Web browsers use the lists from the Google Safe Browsing service for checking pages against potential threats. Google also provides a public API for the service.
According to Google, as of September 2017, over 3 billion Internet devices are protected by this service.
- Web browsers: Google Chrome, Safari, Firefox, Vivaldi, and GNOME Web.
- Android: Google Play Protect, Verify Apps API
- Google Search
- Google AdSense: prevent advertisements to promote dangerous websites
Google maintains the Safe Browsing Lookup API, which has a privacy drawback: "The URLs to be looked up are not hashed so the server knows which URLs the API users have looked up". The Safe Browsing Update API, on the other hand, compares 32-bit hash prefixes of the URL to preserve privacy. The Chrome, Firefox and Safari browsers use the latter.
Google Safe Browsing "conducts client-side checks. If a website looks suspicious, it sends a subset of likely phishing and social engineering terms found on the page to Google to obtain additional information available from Google's servers on whether the website should be considered malicious". Logs, "including an IP address and one or more cookies" are kept for two weeks. They are "tied to the other Safe Browsing requests made from the same device."
Websites carrying ads that are infected might be blacklisted by Google Safe Browsing even when the website itself has no malware. To request removal from the blacklist requires a webmaster to create a Google Webmaster's Tool account which can take several days to be removed.
