WordPress News: Gravatar Data Leak

This week Gravatar, a global service for unique avatars, was breached – although Gravatar assures there was no hack.

Hello everyone, we would like to confirm Gravatar was not hacked and no security protocols have been breached – for more information please visit: https://t.co/hhIQQ5WWKt
— Gravatar.com (@gravatar) December 7, 2021

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.
