#Doge #hack #node $DOGE Dogecoin flaw exploited by hacker, crashes 69% of nodes!
A hacker exploited a critical vulnerability in the Dogecoin network, causing 69% of its nodes to crash.
On Dec. 12, Andreas Kohl, co-founder of Bitcoin sidechain Sequentia, claimed that he had crashed 69% of the Dogecoin network. Kohl said he used an old laptop in El Salvador to execute it.
Data from Blockchair indicated that Dogecoin had 647 active nodes before the vulnerability was exploited. At the time of writing, Dogecoin had 315 active nodes.

Kohl said he used a vulnerability discovered by researcher Tobias Ruck to cause the nodes to crash.
DogeReaper vulnerability similar to a โDeath Noteโ
On Dec. 4, an X account called โDepartment Of DOGE Efficiencyโ publicly disclosed a vulnerability on the Dogecoin network that they said could have crashed the chain entirely. According to the account, the โDogeReaperโ vulnerability allows anyone to crash any Dogecoin node remotely.
The account said that the vulnerability functions like a โDeath Noteโ from the Japanese manga and anime of that name. In that fictional world, writing someoneโs name in a notebook will cause them to die of a heart attack.
The account said that the vulnerability does something similar to Dogecoin nodes. With the DogeReaper, the social media account said, anyone could write a nodeโs address and cause the node to die of a segmentation fault.
The account claimed that since Dogecoin nodes are publicly known, โanyone could crash the entire Dogecoin network in an instantโ using the vulnerability. โIf a malicious actor wouldโve found this bug instead of us, he could have stopped the Dogecoin network for at least a few days, with no transactions or blocks,โ they wrote.
While the vulnerability had potential, the account said Coinbase deemed the severity low and had rewarded Ruck with $200.
