Advisory published Updated
cubaflixdownload is a confirmed malicious PyPI package (MAL-2026-900) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 2.0.0…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in cubaflixdownload (PyPI)
What this malware does
During importing, the code automatically starts a Telegram bot designed to download and save files locally upon a specific message in the channel. While this seems to have limited harm, this behavior is not disclosed and involved packages have typosquatting-like names. The core code is in the "platforms" package

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for cubaflixdownload (7 malicious versions).
If you installed it — respond
cubaflixdownload 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 cubaflixdownload 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 cubaflixdownload-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
