markitanalysisPyPI
Advisory published Updated
markitanalysis is a confirmed malicious PyPI package (MAL-2025-2974) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.1, 0.1.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in markitanalysis (PyPI)
What this malware does
If installed using source package, the package collects selected environment variables, including GITHUB_TOKEN if set, and sends to an external service. The package doesn't hide its actions at all, but there are already multiple different packages with the same code.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2025-01-markitanalysis
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 markitanalysis (2 malicious versions).
If you installed it — respond
markitanalysis 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 markitanalysis 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 markitanalysis-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
