DDoS attacks disrupt Greek secondary-school examination question bank
On 29 and 30 May 2023, distributed denial-of-service attacks targeted the Institute of Educational Policy's online examination question-bank platform hosted by GRNET. Interruptions prevented some schools from obtaining examination materials on time and disrupted scheduling, although the national university-entry examination system was separate and unaffected.
