At least $25bn worth of cryptocurrency is at risk due to “zero-day” exploits across more than 280 blockchain networks, according to cybersecurity firm Halborn. The company worked with Dogecoin, Litecoin and Zcash to fix the vulnerability, dubbed “Rab13s”, which it identified in March 2022 during a security review of Dogecoin’s codebase. Halborn found the same critical and exploitable vulnerabilities in more than 280 other networks. The most serious vulnerability allows attackers to send malicious consensus messages that could force individual nodes to shut down, with this over time exposing the blockchain to a 51% attack. Other vulnerabilities allow potential attackers to crash blockchain nodes by sending Remote Procedure Call requests. Halborn has contacted all affected parties and provided remediation for the vulnerabilities.
