RIPE NCC is warning members that they suffered a credential stuffing attack attempting to gain access to single sign-on (SSO) accounts. RIPE is a not-for-profit regional Internet registry for Europe, the Middle East, and parts of Central Asia. This SSO service is used to login to all RIPE sites, including My LIR, Resources, RIPE Database and RIPE Labs. RIPe urges all users to enable two-factor authentication on their Access accounts to prevent compromise.
