is-it-aiPyPI
Advisory published Updated
is-it-ai is a confirmed malicious PyPI package (MAL-2026-18426) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.1.1, 0.1.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in is-it-ai (PyPI)
What this malware does
In this campaign, specific versions of involved affected packages hide malicious actions. The malicious code is hidden in specific versions of a dependency (is-it-ai), intentionally pinned by specific versions of dependent packages. All package versions were uploaded with malicious intention; the ones without malicious references are clearly intendent only to hide a cover for the rest. When triggered, the malicious action fingerprints the environment and contacts the remote server. If it responds with an URL, it will be downloaded and executed.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

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