Frequently Asked Questions

Who should treat this as an active compromise?

Any computer where the package is installed or running should be considered fully compromised. This includes systems on which it was installed previously, because removing the package may not remove other malicious software.

What should be done immediately?

Rotate all secrets and keys stored on the affected computer immediately, using a different computer. Remove the package, but do not rely on removal alone to restore trust in the system.
