Last weekend, RIPE NCC Access, our single sign-on (SSO) service was affected by what appears to be a deliberate « credential-stuffing » attack, which caused some downtime. We mitigated the attack, and we are now taking steps to ensure that our services are better protected against such threats in the future.

Our preliminary investigations do not indicate that any SSO accounts have been compromised.
