Safe Browsing has been protecting over one billion people from traditional phishing attacks on the web for more than eight years. The threat landscape is constantly changing -- bad actors on the web are using other types of deceptive behavior to trick you into performing actions that you didn’t intend or want, so we’ve expanded protection to include social engineering.

Social engineering is a much broader category than traditional phishing and encompasses more types of deceptive web content. A social engineering attack happens when either:

  • The content pretends to act, or looks and feels, like a trusted entity — like a bank or government.
  • The content tries to trick you into doing something you’d only do for a trusted entity — like sharing a password or calling tech support.

Below are some examples of social engineering attacks that try to trick you into thinking the content is delivered by Google or Chrome. Other trusted brands are also commonly abused for social engineering attacks.

This page tries to trick you into downloading and executing malware or unwanted software. It uses Chrome’s logo and name to confuse you into believing the site is operated by Google. Content like this may include an inconspicuous legal disclaimer that states it is not affiliated with Google. This does not change the deceptive nature of this content -- as always, use caution when downloading files from the web.

This is a fake tech phone support page. This page mimics a warning and may trick you into calling a third-party company that pretends to be Google or some other trusted entity, but charges a fee for support. (Chrome does not offer paid remote support).

This is a fake Google login page. It might trick you into disclosing your account login credentials. Other phishing sites like this could trick you into giving up other personal information such as credit card information. Phishing sites may look exactly like the real site -- so be sure to look at the address bar to check that the URL is correct, and also check to see that the website begins with https://. See more information here.

If we identify that a web page contains social engineering content, Chrome will warn you by displaying the following interstitial.

(If you believe Safe Browsing has classified a web page in error, please report it here.)

We'll continue to improve Google's Safe Browsing protection to help more people stay safer online. Check out the Safe Browsing Transparency Report to find out more.

Earlier this year, we announced that Google Chrome would continue support for Windows XP through the remainder of 2015.  At that time, we strongly encouraged users on older, unsupported platforms such as Windows XP to update to a supported, secure operating system. Such older platforms are missing critical security updates and have a greater potential to be infected by viruses and malware.

Today, we’re announcing the end of Chrome’s support for Windows XP, as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple. Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes.

If you are still on one of these unsupported platforms, we encourage you to move to a newer operating system to ensure that you continue to receive the latest Chrome versions and features.

Over the last few days, there’s been some confusion about the future of Chrome OS and Chromebooks based on speculation that Chrome OS will be folded into Android. While we’ve been working on ways to bring together the best of both operating systems, there's no plan to phase out Chrome OS.

With the launch of Chrome OS six years ago, we set out to make computers better—faster, simpler and more secure—for everyone. We’ve since seen that vision come to life in classrooms, offices and homes around the world. In fact, every school day, 30,000 new Chromebooks are activated in U.S. classrooms—that’s more than all other education devices combined. And more than 2 million teachers and students in more than 150 countries have the Share to Classroom Chrome extension, which launched in September and gets students onto the same webpage, instantly. Meanwhile, companies such as Netflix, Sanmina, Starbucks and of course Google, are using Chromebooks given the ease of deployment, the ability to easily integrate with existing technologies, and a security model that protects users at all levels, from hardware to user data. (Chromebooks are so secure you don’t need antivirus software!) IT administrators can manage tens of thousands of Chromebooks through a single web console, making them ideal for both classrooms and the workplace.

For everyday use, we’re proud that Chromebooks are continually listed as a best-selling laptop computer on In an effort to make computing even more accessible, earlier this year we introduced the first $149 Chromebook—a fast, affordable laptop. And in the next couple weeks the Asus Chromebit will be available—an $85 device that turns any display into a computer so you can replace your old desktop with an affordable computer the size of a candy bar, or let businesses transform a billboard into a smart digital sign.
This year we've also worked to redefine the different forms Chrome OS can take, introduced the first designated Chromebook for Work, and brought more of your favorite Android apps to your Chromebook via Apps Runtime on Chrome (a.k.a. ARC). But there’s more to do. We have plans to release even more features for Chrome OS, such as a new media player, a visual refresh based on Material Design, improved performance, and of course, a continued focus on security. With our regular six-week software cycle and guaranteed auto-updates for five years, Chromebooks keep getting better over time. Finally, stay on the lookout for dozens of new Chromebooks in 2016.

Chrome is one of the world's most popular ways to watch video, with around 3,000 hours of video watched every second. Whether you're singing along with Taylor Swift, binge-watching Breaking Bad or learning about NASA’s Pluto mission—no matter what you watch, we make sure that your videos look great and load fast when you’re using Chrome.

Faster, leaner, crisper

Videos today have higher resolution, richer color and more frames per second. That's great news for you, but as video quality increases, it's harder to stream and play it without interruption. So we’ve been working on keeping Chrome lean so you can watch eye-poppingly high-definition videos. When you use Chrome to watch video on sites like YouTube, your videos load faster and look better than ever before. That's because Chrome supports the VP9 video format, which uses up to 40% less data and higher quality videos.

We optimize for your data plan, battery life and processing power without sacrificing quality and with support for the latest high-definition formats. We’ve also worked with partners like YouTube and Amazon to reduce power consumption up to 25% by transitioning away from Flash.

Keep your videos buttery smooth

Videos really are moving pictures—each picture is called a “frame”. Those frames are recorded by a video camera, and then displayed at regular intervals by your screen so you can see it as a smooth video. A typical video is recorded at 30 frames per second, and a typical screen displays at 60 times a second—so ideally, one frame is on the screen for two refreshes, and you see smooth video. Often that doesn’t happen—many videos aren’t recorded at exactly 30 frames per second, and many screens don’t display at exactly 60 times per second—which leads to inconsistent or jerky video. We’ve been working to take account of these variations in Chrome, so we can more consistently hit two frames per refresh. That means your video looks smoother.

In this example, 32% of video frames are displayed for the wrong length of time and 5 frames never display.  

Now almost all frames are shown at regular intervals, and every frame is displayed.

Your connection may not always be perfect, so we helped build a new open standard that your video provider uses to intelligently adjust video settings—and if your Internet connection speed dips, video quality will adjust without your input. That means you get up to 50% fewer video interruptions.

Keeping you secure

Watching videos on the web used to require downloading and installing a plugin. Plugins are separate programs from the browser and can cause problems, including malware and tracking of your browsing habits across websites.

To combat this, we’ve been working with our partners to create new web standards to support premium content through HTML5. Many leading video providers like YouTube, Amazon and Play Movies now use these standards to deliver video in Chrome, so you don’t have to worry about nasty surprises.

With Chrome, you get the fastest, safest experience while you watch. So you can explore all the great video on the web—to learn, play or get inspired!

Often on the web, we’re doing a ton of things at once -- reading up on an exotic travel location, catching up on social media or booking a hotel. With that in mind, we’re introducing Split View for your iPad (Air 2 or mini 4) to our latest version of Chrome.
We’re also working to make it easier to make purchases on the go. We’re shopping more often than ever on our phones and tablets, but it can be a pain to re-enter credit card information every time you buy something. That’s why we’re bringing Chrome’s Autofill from desktop and Android to iOS. No matter what device you use, you can shop for what you need easily and securely.
To get the latest & greatest for your iPhone / iPad, just update Chrome in the App Store.

You’re browsing the web, checking out the latest news on your favorite band, when suddenly you see a red warning screen: “The site ahead contains malware.” These warnings aren’t new—since 2006, Google Safe Browsing has shown them when you navigate to an unsafe site. The warnings protect you from harms caused by unsafe sites, such as malware infections and phishing attacks. But it hasn’t always been clear why a specific website triggers a warning, and you may want to learn more.

To demystify these warnings, we’re launching a Site Status section in the Transparency Report. The next time you come across a Safe Browsing warning, you can search for the blocked website in the Transparency Report to learn why it’s been flagged by our systems.

The new Site Status section of the Transparency Report replaces our previous Safe Browsing diagnostic page. It includes a clearer interface and simpler explanations of the issues, such as details for sites that host unwanted software. We’ve added it to the Transparency Report so that the Safe Browsing section of the report is a one-stop shop for information to help you understand what Safe Browsing is and how it works.
If a favorite website shows up as “dangerous,” it’s often due to user-uploaded bad content or a temporary malware infection. The Site Status will return to normal once the webmaster has cleaned up the website. To help speed up this process, we automatically give the webmaster a heads-up about the problem via Search Console; if you use Google Analytics, we’ll also warn you there if your site has malware on it. (Webmasters, check the help center to learn how to remove malware from your websites.)

We’re constantly working to keep users safe and informed online. Visit the updated Site Status section in the Transparency Report to experience it yourself.
