csv-parser-helper @1.0.0

Summary

The package is advertised as a CSV parser but ships a postinstall.js that runs on npm install and performs installer-side reconnaissance and exfiltration. It shell-collects hostname, current user, working directory, uname -a , container indicators, process tree, and network information; probes AWS and Tencent instance metadata services at 169.254.169.254 and metadata.tencentyun.com; and dumps the full process environment while filtering out only npm noise (retaining any token/secret-shaped variables such as GITHUB_TOKEN, cloud provider keys, and CI credentials). The collected data is base64-encoded and exfiltrated via HTTP GET query string to a hardcoded Burp Collaborator subdomain at pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com. The package's stated CSV-parsing purpose is a cover story — index.js is unrelated code and no CSV functionality is present.
