In the modern world, data breaches happen with startling regularity. They can happen to giant credit monitoring firms, social networks, or the fast food restaurant down the street. In late 2017, a security research firm found 1.4 billion stolen usernames and passwords floating around unencrypted on the Dark Web, giving even the most unsophisticated hackers a shot at your online accounts. In many cases, you may not realize that your account has been compromised.
As CNET reports, a security tool called Pwned Passwords can help you figure out with a simple search which of your passwords has already been leaked. Created by a regional director at Microsoft named Troy Hunt in August 2017, the free site is designed to make it as easy as possible to check the security of your online accounts. It’s as simple as entering your password into the search bar. In February 2018, Hunt updated his original site to include passwords from more major breaches. The database now features half a billion passwords that have been leaked as part of hacks on sites like MySpace, LinkedIn, DropBox, and Gawker. Some are sourced from breaches you may not have even heard of, but which still contained your information.
