How the Pwnedlist Got Pwned

May 2, 2016

Last week, I learned about a vulnerability that exposed all 866 million account credentials harvested by pwnedlist.com, a service designed to help companies track public password breaches that may create security problems for their users. The vulnerability has since been fixed, but this simple security flaw may have inadvertently exacerbated countless breaches by preserving the data lost in them and then providing free access to one of the Internet’s largest collections of compromised credentials.

Are You on the Pwnedlist?

November 2, 2011

2011 has been called the year of the data breach, with hacker groups publishing troves of stolen data online almost daily. Now a new site called pwnedlist.com lets users check to see if their email address or username and associated information may have been compromised.

Pwnedlist.com is the creation of Alen Puzic and Jasiel Spelman, two security researchers from DVLabs, a division of HP/TippingPoint. Enter a username or email address into the site’s search box, and it will check to see if the information was found in any of these recent public data dumps.
