Summary
Malicious code in @nextco/utils (npm)

On require(), index.js unconditionally calls a telemetry() function at module top level that collects host reconnaissance (hostname, username, __dirname, cwd, OS/arch, Node version) and the list of environment variable names, base64-encodes the payload, and POSTs it over plain HTTP to the hardcoded host attacker.cl. The destination is not associated with the package's stated publisher (@nextco/utils / nextco.me) and the caller has no opt-out. The behavior fires simply by loading the module, giving an attacker installer host identifiers and an env-var name inventory usable to target follow-on credential theft.
