Summary
Malicious code in ts-linter-builders (npm)
Details
index.js imports child_process and contains a hardcoded outbound POST to https://tg-wallet-manager.vercel.app, with additional fetch() calls to the same destination. The code reads environment data and host identifiers and ships them to this attacker-controlled endpoint. The package name advertises a TypeScript linter helper, but the embedded behavior is unrelated to linting and matches the shape of a credential/host-info beacon. The hardcoded third-party Vercel-hosted endpoint, combined with environment reads and child_process import, constitutes an installer-side exfiltration / RCE staging surface with no legitimate purpose for a 'linter builder' package.

All secrets and keys stored on that computer should be rotated immediately from a different computer. 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.
