WordPress News: Gravatar Data Leak
This week Gravatar, a global service for unique avatars, was breached – although Gravatar assures there was no hack.
The data was scraped, which is not a breach because passwords and other private information weren’t taken. Instead, publicly available information was gathered in a way that is not normally easy to obtain. Theoretically, someone would have to know the username of the Gravatar user in order to access the email address of that user. The scraping allowed the attacker to download the usernames and the emails at the same time.
