A significant portion of the Dogecoin network was brought down on December 12th by a hacker who exploited a critical vulnerability. Andreas Kohl, co-founder of Sequentia, a Bitcoin sidechain, claimed responsibility for the attack, stating he used an old laptop in El Salvador to execute it.
Vulnerability Details:
- The attack leveraged a vulnerability discovered by researcher Tobias Ruck, which allows for remote crashing of Dogecoin nodes.
- The vulnerability, dubbed "DogeReaper," functions similarly to the "Death Note" from the Japanese manga, enabling anyone to crash a node by simply inputting its address.
- This vulnerability, if exploited by malicious actors, could have severely disrupted the Dogecoin network, potentially halting transactions and block production for an extended period.
Impact of the Attack:
- The attack resulted in the crash of 69% of Dogecoin's active nodes, significantly impacting network functionality.
- The number of active nodes dropped from 647 to 315 following the exploitation.
Previous Disclosure and Severity Assessment:
- The "Department of DOGE Efficiency" publicly disclosed the "DogeReaper" vulnerability on December 4th, highlighting its potential to crash the entire Dogecoin network.
- Despite the severity of the vulnerability, Coinbase assessed the risk as low and rewarded Ruck with a $200 bounty.
This incident underscores the importance of vigilant security practices and timely vulnerability assessments within the cryptocurrency ecosystem.
