Phishing and malware detection

Google Chrome warns you if the site you're trying to visit is suspected of phishing or malware, using Google’s Safe Browsing technology.

What is phishing and malware?

A phishing attack takes place when someone masquerades as someone else to trick you into sharing personal or other sensitive information with them, usually through a fake website. Malware is software that gets installed on your machine often without your knowledge, and is designed to harm your computer or potentially steal information from your computer.

How does Safe Browsing work?

Safe Browsing works in two ways to help protect you against phishing and malware. First, Google downloads a list of information to your browser about sites that may contain malicious software or engage in phishing. If the URL of the site you're on matches anything in the list, your browser will contact Google’s servers for more information to make a decision. If your computer then decides that you're visiting a risky site, it can warn you about it. 

Second, Safe Browsing helps to protect you against targeted phishing attacks (sometimes called “spear phishing”), where a site may not already be known to Google so isn’t on the list of phishing sites. Chrome does this by analyzing the content on the site and warn you if it seems suspicious.
