Exposed data

Recommended actions

• Change your OVH 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 OVH — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
