The npm package react-shield was identified as containing malware. According to the GitHub Advisory (GHSA-gmx3-395m-pwc2), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the initial compromise, given that the attacker may have gained full control of the system.\n\nAffected users should treat their systems as potentially fully compromised and take appropriate incident response measures.
