Which of the following would be the result of a significant increase in the motivation...

The result of a significant increase in the motivation of a malicious threat actor would be an increase in risk event likelihood. The likelihood of a risk event is influenced by the factors of threat, vulnerability, and exposure. The motivation of a threat actor is a key component of the threat factor, as it reflects the intent and capability of the actor to exploit a vulnerability. Therefore, a higher motivation would imply a higher probability of an attack. An increase in mitigating control costs, risk event impact, or cybersecurity premium are possible consequences of a risk event, but they are not directly affected by the motivation of the threat actor. References = ISACA Certified in Risk and Information Systems Control (CRISC)Certification Exam Question and Answers, question 6; CRISC Review Manual, 6th Edition, page 67.
