Summary
Malicious code in node-app-doctor (npm)
Details
collect.js gathers host identifiers via os.hostname() and os.homedir(), reads local filesystem state with fs.existsSync, spawns child_process commands, and POSTs the collected data to the hardcoded endpoint http://aab.sportsontheweb.net. The destination domain is unrelated to any legitimate npm/Node tooling publisher and there is no plausible benign reason for a 'node app doctor' utility to ship installer/host telemetry to that host. The combination of system enumeration (hostname, home directory, child_process), filesystem inspection, and hardcoded plaintext HTTP POST to an unaffiliated domain is the standard host-fingerprint exfiltration shape.
Decision reason
OSV/OpenSSF confirms node-app-doctor@1.0.1 as malicious package MAL-2026-5733. Malicious code in node-app-doctor (npm)
