EtherRAT: North Korean targeting developers via React2Shell
North Korean–linked attackers exploited a critical React2Shell vulnerability (CVE-2025-55182) to deploy a new smart-contract based RAT named EtherRAT. The malware uses Ethereum smart-contracts for C2 resolution, hides payloads through obfuscation, and employs multiple persistence mechanisms — a serious threat to Web3 and developer environments.
