clean-my-pcnpm
Advisory published Updated
clean-my-pc is a confirmed malicious npm package (MAL-2026-5609) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.1, 1.0.2, 1.0.3…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in clean-my-pc (npm)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for clean-my-pc (6 malicious versions).
If you installed it — respond
clean-my-pc is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If clean-my-pc was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks clean-my-pc-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
