An engineer notices irregular traffic spikes during off-hours in a network-monitoring tool. The spikes involve large outbound data transfers to an IP address geolocated in a high-risk jurisdiction. The traffic uses encrypted channels typically associated with secure file transfers. Which action should the engineer take to analyze the network traffic associated with these potentially malicious activities?

• A.Schedule a maintenance window to update network-encryption protocols and continue monitoring for further anomalies.
• B.Use the network-monitoring tool to track packet payloads and destinations, and cross-reference them with threat-intelligence databases for known malicious IP addresses or domains.
• C.Disregard the traffic as a false positive because encrypted channels imply secure communication.
• D.Increase network bandwidth to accommodate the spikes and avoid potential service disruptions.

Refer to the exhibit.

A web hosting company analyst is analyzing the latest traffic because there was a 20% spike in server CPU usage recently. After correlating the logs, the problem seems to be related to the bad actor activities. Which attack vector is used and what mitigation can the analyst suggest?

• B.SQL Injection; implement input validation and use parameterized queries.
• C.Distributed denial of service; use rate limiting and DDoS protection services.
• D.Phishing attack; conduct regular user training and use email filtering solutions.

Which antiforensic technique is associated with deliberately misleading forensic analysts by altering the content of digital artifacts, making it difficult to reconstruct the original data accurately?
