Adversaries may install a root certificate on a compromised system to avoid warnings when connecting to their command
and control servers. Root certificates are used in public key cryptography to identify a root certificate authority
(CA). When a root certificate is installed, the system or application will trust certificates in the root's chain of
trust that have been signed by the root certificate.
