Version 1.2.2 of font-scrubber contains malicious code as a postinstall script. The package attempts to upload sensitive files from the system to a remote server. The files include configuration files, command history logs, SSH keys and /etc/passwd.

Recommendation

Any computer that has this package installed or running should be considered fully compromised. 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.
