What happened
In June 2019, the France-based art valuation website Artvalue.com (now defunct) left their 158k member subscriber base publicly exposed in a text file on their website. The exposed data included names, usernames, email addresses and passwords stored as MD5 hashes. The site operator did not respond when contacted about the incident, although the exposed file was subsequently removed.

What was exposed
Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
Passwords: The secret you use to sign in, stored by the breached service either in plain text, in a scrambled form called a hash, or encrypted. How it was stored decides how quickly it can be recovered.
Salutations: The title used before your name, such as Mr, Mrs, Ms, Mx, Dr or Rev, stored so letters and emails can address you formally.
Usernames: The handle or login name you chose for an account, which may be public on forums, games and social platforms or used privately to sign in.
