PANews reported on December 12 that according to Cointelegraph, Andreas Kohl, co-founder of Bitcoin sidechain Sequentia, exploited the "DogeReaper" vulnerability, causing 69% of the nodes in the Dogecoin network to crash. On-chain data showed that before the vulnerability was exploited, Dogecoin had a total of 647 active nodes, but now only 315 remain.

The vulnerability was discovered by security researcher Tobias Ruck, allowing attackers to crash nodes by remotely triggering a memory segmentation fault. Relevant analysis pointed out that if the vulnerability is exploited on a large scale by malicious parties, it may cause the entire network to stop operating for several days, with no transactions or blocks generated. Despite the huge potential threat of the vulnerability, Coinbase only provided a $200 reward for reporting.

Andreas Kohl later said that the Dogecoin vulnerability only affects nodes that have not been updated to the latest version, which account for the majority of the network, but does not include centralized exchanges (CEX) and other major custodians. Therefore, most Dogecoin users were not affected by the incident, and most users have limited knowledge of the self-custody mechanism.
