All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

What systems should be treated as exposed?

Any computer where the package is installed or running should be considered fully compromised. This includes systems that may hold secrets or keys accessible from that computer.

2

What immediate response is recommended?

Rotate all secrets and keys stored on the affected computer immediately, using a different computer. Remove the package from the affected system.
