On import, the payload stashes `global.r = require` and `global.m = module`, then issues HTTPS requests to an Ethereum public RPC endpoint (h.drpc.org) and a block-explorer account API to read state from contract 0xa322E5f3..., using that state to resolve a next-stage URL that is fetched and executed in-process. The obfuscated string array (~303 entries via a rotated decoder) hides `drpc.org`, `?module=ac`, `POST`, `application/json`, `Mozilla/5.`, and the contract address. This is the EtherHiding loader pattern: attacker-controlled contract state serves as a mutable pointer to arbitrary code executed in the installer/consumer process at require time. Behavior does not match the package's advertised purpose of a small typed capability contract.\n\n## Source: ghsa-malware (e250ba61dd9623df22f284b1b5c2e41513954b57d1e4cc099f2321179a0673cc)\nAny computer that has this package installed or running should be considered fully compromised.
