C. Relevancy of the social media activity is not important in threat hunting.
D. A comprehensive analysis of all social media activity is necessary.

A

B. Rapidly responding to the social media activity is the main focus.

While threat hunting generally involves actively searching for indicators of compromise or suspicious activity within an organization’s network or systems, when it comes to social media, the context shifts slightly. In this scenario, the unusual activity on the company’s social media account could represent a different set of threats (e.g., reputation damage, phishing attempts, spreading of malware links) than those typically found within internal networks. In the context of social media, rapid response becomes particularly important due to the public and potentially viral nature of social media platforms. Quickly identifying and addressing suspicious activity can help prevent the spread of harmful content, protect the organization’s reputation, and mitigate any potential security risks associated with the activity. While the broader threat-hunting process involves a methodical investigation to uncover hidden threats, the immediate need to respond to and manage unusual social media activity underscores the importance of speed in this context.
