Deribit, a cryptocurrency futures& options exchange, claimed on Sep 21 that it was experiencing DDOS attacks which made it difficult to reach their servers. Hours later it updated its progress in blocking the attacks, saying that DDOS had been successfully stopped and several measures had been taken to reduce potential weaknesses. As it stressed, the DDOS attempt made use of public endpoints, making it more difficult to reach its platform, yet the system has not been breached in any way.
