About This Breach

The listed fields include dates of birth, email addresses, homepage URLs, instant-messaging identities, IP addresses, passwords, security questions and answers, spoken languages, and website activity.

Reused passwords and security answers create an account-takeover risk. Forum profiles, messaging identities, and website activity can be linked across accounts, making specialized verification requests more convincing.

A match means that the queried email address or related profile information corresponds to a listed field; it does not prove that every field was exposed for the same person. Change passwords and security answers, close old sessions, and verify forum or account-recovery requests through official channels.

Verification and editorial method

LeakData compares the incident name, date, affected-record count, and exposed data types with accessible sources. Unverified fields are not presented as facts, and records are updated when new evidence becomes available.
