Blockchain security firm, Halborn has detected several critical and exploitable vulnerabilities impacting more than 280 networks, including Litecoin (LTC) and Zcash (ZEC). Code-named “Rab13s,” this vulnerability has put over $25 billion of digital assets at risk.

This was first detected in the Dogecoin network a year ago, which was then fixed by the team behind the premier memecoin.
