Question 1 of 30👑 VIP
A security analyst is reviewing network captures from a suspected intrusion. She notices that an internal host is sending out small, periodic DNS TXT record queries to randomized subdomains of a domain not in the corporate whitelist. The queries occur every 90 seconds and the subdomain labels appear to be Base64-encoded. No corresponding outbound HTTP/S traffic is observed. Which attack technique is most consistent with this behavior?
