ggfmttygl-newPyPI
Advisory published Updated
ggfmttygl-new is a confirmed malicious PyPI package (MAL-2026-3406) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for ggfmttygl-new (6 malicious versions).
If you installed it — respond
ggfmttygl-new 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 ggfmttygl-new 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 ggfmttygl-new-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
