Have I Been Pwned (HIBP) is a data breach “search engine” that allows anyone to submit their email address to see if any links to a data breach are publicly known. Also: AT&T customer? Claim up to $7,500 from $177M data breach settlement — don’t miss the new deadlineHIBP is a free service that can give you an overview of whether or not it is likely your online accounts have been “pwned,” or compromised, in a data breach. Once you’ve submitted your email address for review, you are told how many data breaches, if any, your information has been leaked in. A timeline will show when the data breach occurred, along with a useful summary of the stolen or dumped data. Also: I’m ditching passwords for passkeys for one reason – and it’s not what you thinkYou can also use the HIBP side service, Pwned Passwords, to see if a password you commonly use is linked to exposed datasets. You can’t use the service to view stolen or leaked data. Instead, HIBP gives you an overview of compromised data. At the time of writing, 917 breaches have been added to the service, which now brings its count to 15.32 billion accounts. What information is included in these datasets?According to the Have I Been Pwned updates, the first set includes 183 million records. Data was uploaded to HIBP on Oct. 21 with the assistance of Synthient, a threat intelligence service that shared the data with Hunt. In total, 183 million unique email addresses, the websites they were used on, and the passwords they were associated with were included.

Added to HIBP on Oct. 27, this data breach relates to MyVidster, a video-sharing website that closed earlier this year and was reportedly used to bookmark and share pornography. Email addresses, usernames, and profile pictures were leaked on a public hacking forum. More
