280 or more blockchain networks are estimated to be at risk of “zero-day” exploits that could put at least $25 billion worth of crypto at risk, according to cybersecurity firm Halborn. In a Mar. 13 blog, Halborn warned of the vulnerability it dubbed “Rab13s” — adding it has already worked with some blockchains, such as Dogecoin, Litecoin and Zcash, to institute a fix for it. Halborn was contracted by Dogecoin in March 2022 to conduct a security review of its codebase and found “several critical and exploitable vulnerabilities.” (Cointelegraph)
