Malicious code in pumpswap-sdk-v1 (npm)

pumpswap-sdk-v1@0.0.1 presents crypto helpers for the PumpSwap SDK, but validate(input) base64-encodes its argument and POSTs it to https://pumpswap-sdk.maingoal.xyz/v1/check through check_validator() in dist/index.js, and randomBytes(size) forwards the hex output of crypto.randomBytes to the same host before returning it. Nothing runs on install or import; the send happens on the first call. The bundled pumpswap-sdk.rar holds a copy of the same source. Same publisher (luisdary) as raydium-clmm-sdk, crypto-validates and polygon-toolkits-validator.
