Dogecoin Network’s Patched Bug is Still Present in 280 Blockchains: A Critical Vulnerability for Cryptocurrencies

The security and stability of cryptocurrencies have always been a critical concern for investors and developers. With the rise of decentralized blockchain technology, cryptocurrencies have become more popular than ever, and their security has become more crucial. Unfortunately, a recent report from the blockchain security firm Halborn has shown that a vulnerability found last year on the open-source codebase of the Dogecoin network is still present in at least 280 other networks, including Litecoin and Zcash. This vulnerability is known as “Rab13s,” and it is a critical concern for the security and stability of cryptocurrencies.

The Significance of the Vulnerability

Halborn discovered several critical vulnerabilities in the Dogecoin network in 2022, which the developers addressed and resolved. However, further investigations by Halborn revealed that similar vulnerabilities were present in several other networks, including Litecoin and Zcash. This could potentially expose over $25 billion worth of tokens to potential security risks. Due to codebase differences between the networks, not all vulnerabilities are exploitable on all the networks, but at least one of them may be exploitable on each network. On vulnerable networks, a successful exploitation of the relevant vulnerability could lead to denial of service or remote code execution.

The Technical Details of the Vulnerability

The most critical vulnerability found in the affected networks pertains specifically to the way peer-to-peer (p2p) communications are conducted in these networks. An attacker can send malicious consensus messages to individual nodes in the network, causing them to shut down and leaving the entire network vulnerable to 51% attacks or other severe issues. While some of the vulnerabilities were previously found on the bitcoin network, Halborn also identified a zero-day vulnerability that was uniquely related to Dogecoin. This particular vulnerability was related to Remote Procedure Call (RPC) services, which could allow attackers to execute code remotely and impact individual miners.

Responsible Disclosure Efforts

Halborn made a good faith effort to contact the affected networks for responsible disclosure. The severity of the Rab13s vulnerabilities, coupled with the simplicity of the p2p messaging mechanisms, increases the likelihood of attack. However, due to the severity of the vulnerabilities, Halborn is not releasing further technical or exploit details at this time.

Implications for the Future of Cryptocurrencies

The discovery of the Rab13s vulnerability in Dogecoin and its presence in other cryptocurrencies is a stark reminder of the potential security risks associated with cryptocurrencies. While decentralized blockchain technology offers many advantages over traditional centralized systems, it also presents unique security challenges that must be addressed. The vulnerability in question highlights the need for ongoing security assessments and timely patching of vulnerabilities by developers to maintain the integrity of these systems.


In conclusion, the presence of the Rab13s vulnerability in Dogecoin and other cryptocurrencies is a critical concern for the security and stability of the crypto market. The vulnerability highlights the importance of ongoing security assessments and responsible disclosure efforts by blockchain security firms and developers. As the crypto market continues to evolve and gain widespread adoption, it is crucial that the security and stability of these systems are maintained to ensure the safety of investors and the integrity of the market.
