Protecting Against Google Phishing in Chrome
Google has a new Chrome extension called “Password Alert”:
To help keep your account safe, today we’re launching Password Alert, a free, open-source Chrome extension that protects your Google and Google Apps for Work Accounts. Once you’ve installed it, Password Alert will show you a warning if you type your Google password into a site that isn’t a Google sign-in page. This protects you from phishing attacks and also encourages you to use different passwords for different sites, a security best practice.
Here’s how it works for consumer accounts. Once you’ve installed and initialized Password Alert, Chrome will remember a “scrambled” version of your Google Account password. It only remembers this information for security purposes and doesn’t share it with anyone. If you type your password into a site that isn’t a Google sign-in page, Password Alert will show you a notice like the one below. This alert will tell you that you’re at risk of being phished so you can update your password and protect yourself.
It’s a clever idea. Of course it’s not perfect, and doesn’t completely solve the problem. But it’s an easy security improvement, and one that should be generalized to non-Google sites. (Although it’s not uncommon for the security of many passwords to be tied to the security of the e-mail account.) It reminds me somewhat of cert pinning; in both cases, the browser uses independent information to verify what the network is telling it.
EDITED TO ADD: It’s not even a day old, and there’s an attack.
