A security analyst notices repeated communication attempts to an external IP address from several internal hosts at regular intervals. This behavior is most likely indicative of which type of malicious activity?
Malicious processes
Data exfiltration
Beaconing
Privilege escalation
The observed regular intervals of communication attempts suggest 'beaconing.' Beaconing is a technique used by malware to communicate with a command and control server at specific intervals to receive instructions or exfiltrate data. Other similar activities like 'data exfiltration,' involve the unauthorized transfer of data out of the network but do not necessarily involve regular communication, and 'privilege escalation' involves gaining higher access levels within a system, unrelated to the observed behavior.
