• Dogecoin, Zcash, and Litecoin have patched security vulnerabilities discovered by blockchain security firm Halborn.
• Over 280 other blockchains contain similar vulnerabilities, which could put more than $25 billion of crypto at risk.
• Halborn has shared exploit kits with the projects so that they can patch the issues accordingly.
Vulnerabilities Discovered in Multiple Blockchains
Security firm Halborn recently reported that more than 280 blockchains contain varying levels of vulnerability under the collective term “Rab13s”. The most common vulnerability allows attackers to take unpatched blockchain nodes offline by sending consensus messages to those nodes, making it easier for an attacker to conduct a 51% attack against the network or otherwise harm it. A secondary vulnerability allows an attacker to halt nodes through an RPC request, while a third vulnerability allows attackers to execute code via RPC (though this requires valid credentials).
Dogecoin, Zcash and Litecoin Resolve Vulnerabilities
Halborn was contracted to inspect Dogecoin’s code in March 2022 and reported that any potential vulnerabilities were patched soon after. Similarly, Zcash released an update addressing the issue on March 13th, claiming that no attack had been made against their network as of yet. Litecoin also addressed the issue on March 12th without directly mentioning Halborn or its findings. Horizen also stated they were informed of the possible vulnerability by Halborn and published a fix on March 13th.
Over $25 Billion At Risk
Halborn warned these exploits could put over $25 billion worth of assets at risk due to their widespread nature across various blockchains. Exploit kits have been shared with all relevant projects so they can patch these issues accordingly and minimize further damage from occurring.
No Evidence Of Attacks Yet
So far there is no evidence suggesting any attacks have occurred regarding these vulnerabilities but it is always important for users to remain vigilant when using cryptocurrency networks and keep their software updated with all patches released by developers as soon as possible in order to protect themselves from potential attack vectors like this one.
Conclusion
It is clear that multiple blockchains are vulnerable to certain exploitations if left unpatched – luckily we now know what these exploits are and how they can be addressed moving forward thanks in large part due to Halborn’s research into this topic. Hopefully these networks will be able to resolve any issues before any further damage can occur as a result of them being exploited maliciously by hackers or bad actors looking for ways into vulnerable systems!
