Dogecoin Network Hit by Vulnerability, 69% of Nodes Crashed

A hacker exploited a major security vulnerability in the Dogecoin network on Dec. 12, crashing 69% of its active nodes. Andreas Kohl, co-founder of Bitcoin sidechain Sequentia, identified himself as the hacker in a post on X. Kohl said he used an old laptop in El Salvador to carry out the cyberattack. The Doge network had 647 active nodes before the attack, but only around 315 remained functional afterward, according to data from Blockchair. At the time of publishing, 376 are currently functional.
