Researchers from a Web3 security company have recently discovered a number of serious flaws in the Dogecoin, Litecoin, and Zcash blockchains. The most critical vulnerability affects P2P communications, allowing attackers to craft malicious consensus messages to key nodes and cause them to shut down. What's more concerning is that there is a possibility that similar bugs may exist in around two hundred other networks. If cybercriminals manage to exploit these flaws before Halborn receives payment for fixing it, it could put over $25 billion worth of digital assets at risk.

PeckShield, a blockchain security firm, warns that zero-transfer scammers are behind two of the largest gas spenders. The scheme is as follows: 🛑 Fake addresses are created by imitating real ones. 🛑 The TransferFrom function is then used to make a zero transfer from any wallet to a smart contract. 🛑 As a result, a fake transaction history is created and shown in users' wallets and on Etherscan. The only thing left to do is wait for the transfer from the victims who did not thoroughly check the address before sending the money.
