toorcPyPI
Advisory published Updated
toorc is a confirmed malicious PyPI package (MAL-2026-6290) that steals credentials and exfiltrates sensitive data (malicious version 0.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in toorc (PyPI)
What this malware does
On pip install (and even pip download), the package's setup.py overrides the install and egg_info commands to execute a RunCommand() routine that serializes every entry in os.environ into a key=value query string and captures the output of ps -elf. The combined payload is then POSTed via curl over plaintext HTTP to http://gjampdwmdjmppwedtkpbbdkq05f6iiz6r.oast.fun, a unique subdomain on the public interactsh out-of-band testing service. Any CI/build secrets present in the environment at install time (AWS_*, GITHUB_TOKEN, NPM_TOKEN, CI provider tokens, etc.) leak to the attacker-controlled OAST listener, along with a snapshot of running processes on the host.
During installation, the package exfiltrates env variables
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Reasons (based on the campaign):
-
The package overrides the install command in setup.py to execute malicious code during installation.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for toorc (version 0.0.1).
If you installed it — respond
toorc 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 toorc 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 toorc-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
