chrome-stealthPyPI
Advisory published Updated
chrome-stealth is a confirmed malicious PyPI package (MAL-2026-28) 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 chrome-stealth (PyPI)
What this malware does
By using the package, the computer is attached to participate in a proxy network and share its IP and bandwidth. This is clearly stated, but the package has no real functionality besides that. Additionally, the stated proxy network seems extremely shady: the domain was just registered, is closely similar to a long-existing service, and offers residential proxy only for cryptocurrencies. The company mentioned in the package information does not have a website, and the proposed way to opt-out does not work.

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