Fanlore Data Breach Exposes 145K Email Addresses and Hashed Passwords Earlier this month, Fanlore a wiki platform focused on fandom and pop culture suffered a data breach compromising 145,000 unique email addresses, along with usernames and passwords. The exposed passwords were stored as MD5 or PBKDF2 hashes, with weaker MD5 hashes posing a higher risk of decryption. Security researchers noted that 23% of the leaked email addresses had already appeared in previous breaches, including the 2021 LinkedIn data exposure. The incident highlights persistent vulnerabilities in password storage practices, particularly the continued use of outdated hashing algorithms like MD5. While the breach’s exact cause remains undisclosed, the exposure underscores the ongoing risks of credential reuse and the need for stronger security measures in user data protection. The compromised data has been added to breach notification services for affected individuals to assess their exposure.
