coloraizPyPI
Advisory published Updated
coloraiz is a confirmed malicious PyPI package (MAL-2025-5102) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.1, 1.0.2, 1.0.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in coloraiz (PyPI)
What this malware does
The package imitates colorama, and places a proxy object over the original colorama module that on every usage executes a remote code. The remote script installs a backdoor through legitimate tunnelling software and upload access credentials to the attacker.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for coloraiz (3 malicious versions).
If you installed it — respond
coloraiz 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 coloraiz 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 coloraiz-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
