clip-loggerPyPI
Advisory published Updated
clip-logger is a confirmed malicious PyPI package (MAL-2026-5293) 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.
Malicious code in clip-logger (PyPI)
What this malware does
The package contains code to steal clipboard content to a predefined remote location. If run in the right way, the code will periodically check the clipboard and if the content matches the pattern, exfiltrates it. Early versions contain this behavior mentioned in the README. The targeted data are likely cryptocurrency secret seed phrases.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for clip-logger (8 malicious versions).
If you installed it — respond
clip-logger 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 clip-logger 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 clip-logger-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
