handyfilesPyPI
Malicious code in handyfiles (PyPI) Remove it immediately and rotate any exposed credentials.
What this malware does
During the installation, the package iterates its files and attempts to import a hidden module - which is embedded as ZIP archive in the image file
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2024-12-handyfiles
Reasons (based on the campaign):
-
The package overrides the install command in setup.py to execute malicious code during installation.
-
obfuscation

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for handyfiles (version 0.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging handyfiles across your stack and pipelines.
If you installed it — respond
handyfiles 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 handyfiles was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks handyfiles before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

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