PANews reported on December 15 that according to News.bitcoin, Dogecoin was recently attacked by a vulnerability that seriously affected its node structure. The vulnerability is called "Dogereaper". It is reported that Sequentia developer Andreas Kohl used only an old laptop from El Salvador to crash 69% of Dogecoin nodes. Although this attack seriously affected Dogecoin nodes, the situation could have been worse: ecash developer Tobias Ruck and another developer Roqqit have disclosed the vulnerability. Tobias Ruck said that he first discovered this vulnerability when developing Doged (a replacement for Dogecoin Core), and found an unfixed segmentation fault in the original code when testing the ported code for their replacement software.

Tobias Ruck explained: “We will not tolerate node crashes. We put a lot of effort into ensuring the security of the network. This attack could have been much more serious. All important stakeholders, such as miners, exchanges, etc., had already patched it long before the attack occurred, which shows how important it is for us to act with caution.”
