Artvalue.com data breach

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 data leaked

• Email addresses
• Names
• Passwords
• Salutations
• Usernames

What to do if you had an account

1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
