What best describes the action needed to handle someone who threatens to release sensitive data?

Reporting the threat to authorities is the most appropriate action when someone threatens to release sensitive data. This step is crucial as it helps ensure that trained professionals can assess the situation and determine the necessary response. Authorities, such as law enforcement or cybersecurity teams, have the expertise and resources to investigate the threat, potentially mitigate any potential release of sensitive information, and hold the perpetrator accountable.

Taking this action also helps to create an official record of the incident, which can be important for both legal and organizational responses. It demonstrates a commitment to protecting sensitive data and can support the organization in developing future security measures based on the incident.

While other actions may seem plausible, they do not effectively address the immediate risk posed by the threat. Ignoring the threat could lead to severe consequences, and engaging in negotiations may not be advisable as it could escalate the situation or give the aggressor confidence. Implementing stronger security measures after a threat does not resolve the current issue and may not be sufficient if the underlying risk is not dealt with strategically through appropriate reporting channels.
