Malicious Package in kraken-api

Summary

Version 0.1.8 of `kraken-api` contains malicious code as a postinstall script. When installed, the package calls home to a Command and Control server to execute arbitrary commands. ## 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. Users may consider downgrading to version 0.1.7 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.
