pyroviderPyPI
Advisory published Updated
pyrovider is a confirmed malicious PyPI package (MAL-2025-191836) that steals credentials and exfiltrates sensitive data (malicious versions 10.0.1, 10.0.2, 10.0.3…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in pyrovider (PyPI)
What this malware does
On importing the module, package exfiltrates basic data like username. It's obfuscated with a lot of meaningless text and has no other purpose
Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.
Campaign: 2025-03-pyrovider
Reasons (based on the campaign):
- The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for pyrovider (6 malicious versions).
If you installed it — respond
pyrovider 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 pyrovider 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 pyrovider-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
