Dogecoin, one of the most popular meme-inspired cryptocurrencies, faced a serious network exploit that crashed 69% of its nodes, highlighting serious security concerns.
Vulnerabilities expose network weaknesses
On December 12, Andreas Kohl, co-founder of Bitcoin sidechain Sequentia, announced that he had successfully crashed 442 of Dogecoin’s 647 active nodes using an old ThinkPad laptop and a vulnerability called “DogeReaper.”
The exploit, first disclosed by the “DOGE Efficiency Department” on December 4, allows anyone to remotely disable a Dogecoin node by leveraging a segmentation fault in the network code.
A segmentation fault occurs when a program attempts to access memory for which it is not authorized, and the operating system prompts it to terminate that memory for safety reasons. A majority of Dogecoin nodes were compromised, reducing the network’s ability to process transactions.
Following Kohl’s demo, Dogecoin’s active nodes fell from 647 to 315, according to data from Blockchair. As of this writing, there are 386 nodes active.
“DogeReaper” Threat
A critical vulnerability called “Gogecoin Reaper” allows attackers to remotely crash any Dogecoin node by targeting public addresses. According to DOGE, the node will be “terminated immediately” due to a segmentation error.
Since Dogecoin nodes are publicly accessible, malicious actors could exploit this flaw to cause widespread network shutdowns. The DOGE efficiency department warned that such an attack could paralyze the network for at least several days, completely halting transactions and block production.
“This would have generated a lot of FUD and the $DOGE price would certainly have been closer to $0 than $1,” the group said.
Patches are available, but adoption is delayed
The “DogeReaper” vulnerability was first identified by Bitcoin Monk Tobias Ruck and developer Roqqit. Roqqit privately notified miners and cryptocurrency exchanges to mitigate the immediate threat.
Although the patch was quickly released, many Dogecoin nodes failed to update, leaving the network exposed.
DOGE’s efficiency unit criticized exchanges like Coinbase for minimizing risk and classified the exploit as “low severity.”
“We have never received confirmation that Coinbase has implemented an updated, secure version of Dogecoin,” Roqqit expressed disappointment.
Why This Matters
The Dogecoin attack highlights the urgent need for stronger security measures and timely updates to maintain trust in cryptocurrency networks, while also highlighting broader challenges in protecting blockchain ecosystems and ensuring network stability.
