Artvalue Data Breach

What happened

In June 2019, the France-based art valuation website Artvalue.com 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.

Exposed data

Recommended actions

• Change your Artvalue password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Artvalue — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
