license-utils-kitPyPI
Advisory published Updated
license-utils-kit is a confirmed malicious PyPI package (MAL-2026-2084) that steals credentials and exfiltrates sensitive data (malicious versions 0.1a0, 0.1a1, 0.1b1…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in license-utils-kit (PyPI)
What this malware does
Malicious clone of legitimate "license" package. When using the find_by_key function, the malicious code from strongly obfuscated files is loaded. It then at least collects data from cryptowallets and password managers and exfiltrate them to a hardcoded remote location.
Prior version 0.1b2, the malicious code was hosted externally and downloaded when triggered.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for license-utils-kit (9 malicious versions).
If you installed it — respond
license-utils-kit 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 license-utils-kit 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 license-utils-kit-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
