RIPE NCC announced to have suffered a credential stuffing attack attempting to gain access to single sign-on (SSO) accounts.

The RIPE NCC is a not-for-profit membership association, a Regional Internet Registry and the secretariat for the RIPE community supporting the Internet through technical coordination.

It has over 20,000 members from over 75 countries who act as Local Internet Registries (LIRs) and assign blocks of IP addresses to other organizations in their own country.

The organization mitigated the attack and its investigation confirmed that not SSO accounts have been compromised.

“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,” reads a statement published by the organization.  

“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.”
