A hacker exploited a critical vulnerability in the Dogecoin network, causing 69% of its nodes to crash.

駭客利用狗狗幣網路中的一個嚴重漏洞，導致其 69% 的節點崩潰。

On December 12th, Andreas Kohl, co-founder of Bitcoin sidechain Sequentia, claimed responsibility for crashing 69% of Dogecoin's network.

12 月 12 日，比特幣側鏈 Sequentia 聯合創始人 Andreas Kohl 聲稱對狗狗幣網路 69% 的崩潰負責。

Kohl revealed that he used an old laptop in El Salvador to carry out the exploit.

科爾透露，他在薩爾瓦多使用一台舊筆記型電腦來實施該漏洞。

Before the attack, data from Blockchair showed Dogecoin had 647 active nodes.

在攻擊發生之前，Blockchair 的數據顯示狗狗幣有 647 個活躍節點。

Following the breach, the network was reduced to 315 active nodes.

漏洞發生後，網路活躍節點減少至 315 個。

Kohl explained that the exploit leveraged a vulnerability discovered by researcher Tobias Ruck.

Kohl 解釋說，該漏洞利用了研究員 Tobias Ruck 發現的漏洞。

DogeReaper: A Fatal Flaw

DogeReaper：致命缺陷

On December 4th, an X account called "Department Of DOGE Efficiency" publicly disclosed a vulnerability in the Dogecoin network that could have crashed it entirely.

12 月 4 日，一個名為「DOGE Efficiency 部門」的 X 帳戶公開披露了狗狗幣網路中的一個漏洞，該漏洞可能導致其完全崩潰。

The vulnerability, dubbed "DogeReaper," enables anyone to remotely crash Dogecoin nodes.

這個漏洞被稱為“DogeReaper”，任何人都可以遠端破壞狗狗幣節點。

The account likened the flaw to the "Death Note" concept from Japanese manga and anime, where writing someone's name in a notebook leads to their death by heart attack. Similarly, DogeReaper allows attackers to target a node's address, causing it to fail due to a segmentation fault.

該帳戶將該缺陷比作日本漫畫和動畫中的「死亡筆記」概念，即在筆記本上寫下某人的名字會導致該人因心臟病而死亡。同樣，DogeReaper 允許攻擊者瞄準節點位址，導致節點因分段錯誤而失敗。

In computing, a segmentation fault occurs when a program tries to access restricted memory, prompting the operating system to halt the program for safety.

在計算中，當程式嘗試存取受限記憶體時，就會發生分段錯誤，促使作業系統出於安全考慮而停止程式。

The account warned that because Dogecoin node addresses are public, "anyone could crash the entire Dogecoin network in an instant" using this vulnerability.

該帳戶警告說，由於狗狗幣節點地址是公開的，因此「任何人都可以利用此漏洞立即使整個狗狗幣網路崩潰」。

"If a malicious actor had discovered this bug instead of us, they could have stopped the Dogecoin network for at least a few days, with no transactions or blocks," the account stated.

該帳戶表示：“如果惡意行為者而不是我們發現了這個錯誤，他們可能會阻止狗狗幣網路至少幾天，沒有交易或區塊。”

Despite the significant potential for damage, the account reported that Coinbase classified the vulnerability as low severity and rewarded Tobias Ruck with $200 for the discovery.

儘管造成損害的可能性很大，但該帳戶報告稱，Coinbase 將該漏洞歸類為低嚴重性，並獎勵 Tobias Ruck 200 美元以獎勵其發現。
