Exfiltrates collected host or credential data from bundled npm package code. eslint-helper@4.0.2 (same publisher he.s.h.u.lal.a@gmail.com) implements the credential-stealing payload. _k9b2x() enumerates and reads sensitive configuration and credential files; _gsh() reads shell history files. Collected data is serialized and POSTed to the C2 endpoint. The C2 URL is base64-encoded inline to evade naive string scanning.
