OpenSSF/OSV advisory MAL-2026-5609 confirms this npm version as malicious. The package's collect.js imports child_process, fs, http, https, and os, gathers host identifiers via os.hostname() and os.homedir(), reads files from the local filesystem (fs.existsSync checks at lines 20 and 27), and POSTs the collected data to a hardcoded external endpoint at http://aab.sportsontheweb.net (referenced at line 13, with the POST request at line 366)...

Summary
Malicious code in clean-my-pc (npm)
Details
The package's collect.js imports child_process, fs, http, https, and os, gathers host identifiers via os.hostname() and os.homedir(), reads files from the local filesystem (fs.existsSync checks at lines 20 and 27), and POSTs the collected data to a hardcoded external endpoint at http://aab.sportsontheweb.net (referenced at line 13, with the POST request at line 366). The destination domain is unrelated to any legitimate PC-cleaning utility purpose and matches the structural fingerprint of a host-information / filesystem exfiltration beacon: hardcoded non-publisher C2 + system identity collection + outbound POST. Installing or loading this package causes the installer's hostname, home-directory contents indicator, and other host data to be transmitted to the attacker-controlled endpoint over plaintext HTTP.
Decision reason
OSV/OpenSSF confirms clean-my-pc@1.0.9 as malicious package MAL-2026-5609. Malicious code in clean-my-pc (npm)
