The most critical flaw was related to the “zero-day” vulnerability. The exploit allowed an attacker to remotely execute code on a mining node or carry out a DоS-attack.
4/ Another zero-day identified by Halborn was uniquely related to #Dogecoin, including an RPC vulnerability impacting individual miners.
Subsequently, variants of these 0-days were also discovered in similar blockchain networks potentially leading to DoS or RCE attacks.
