orchestrilPyPI
Advisory published Updated
orchestril is a confirmed malicious PyPI package (MAL-2026-18142) that steals credentials and exfiltrates sensitive data (malicious version 0.1.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in orchestril (PyPI)
What this malware does
This campaign consists of similar loader packages, which provide executing code from a given URL. While they do not contain the malicious payload and the usage remains unknown, they are clearly a coordinated campaign to place multiple deceptive ways to load malicious code.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for orchestril (version 0.1.0).
If you installed it — respond
orchestril 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 orchestril 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 orchestril-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
