The 'kartykgithub-multiversion-a' npm package versions 1.0.0 and 1.0.1 contain embedded malicious code that, when installed or executed, fully compromises the host system. This compromise allows an external entity to gain control over the affected computer. Due to the severity of the compromise, all credentials and secrets stored on the machine should be considered exposed and must be rotated from a secure environment. Removal of the package does not ensure complete eradication of the malicious presence.

Any system with this package installed or running is fully compromised, potentially allowing attackers full control over the machine. All sensitive information such as secrets and keys stored on the system are at risk of exposure and misuse. The compromise is severe enough that simply uninstalling the package does not guarantee removal of all malicious artifacts.

Remove the 'kartykgithub-multiversion-a' package immediately from affected systems. Rotate all secrets and keys stored on the compromised machine from a separate, trusted device. Due to the full compromise, consider rebuilding the affected system to ensure complete removal of malicious software.
