Deobfuscation of the string table reveals hardcoded references to public Ethereum RPC endpoints (eth.drpc.org, 1rpc.io), an etherscan-style API query (?module=ac...), a hardcoded Ethereum contract address 0xa322E5f3..., a spoofed Mozilla/5.0 User-Agent, JSON POST machinery, and the sinks require, pipe, and eval. The composition matches the EtherHiding on-chain-C2 dropper pattern: on import, the code queries a smart contract via a public Ethereum RPC to retrieve an attacker-controlled next-stage payload string, then passes it to eval() in the consumer's Node process, yielding arbitrary remote code execution against the installer. The on-chain payload storage is mutable by the contract owner but immutable to registry takedown and invisible to standard registry scanners. The README's claim of 'no executable binary' contradicts the shipped dist/index.js.\n\n## Source: ghsa-malware (7c45b346a08bc4c5f14a329f93f928988e7af1039d941528911a1a36080fdc9e)\nAny computer that has this package installed or running should be considered fully compromised.
