North Korea-linked Actors Exploit React2Shell to Deploy New EtherRAT Malware

EtherRAT is a new remote access trojan that uses Ethereum smart contracts for command-and-control communications and implements five different Linux persistence mechanisms. This represents active exploitation of a critical security flaw by state-sponsored actors.
