A client recently hired a penetration testing firm to conduct an assessment of their consumer-facing web application. Several days into the assessment, the client's networking team observes a substantial increase in DNS traffic. Which of the following would most likely explain the increase in DNS traffic?
Correct Answer: A
An increase in DNS traffic during a penetration test suggests data exfiltration using DNS tunneling, a method where attackers encode data into DNS queries to avoid detection. * Option A (Covert data exfiltration) #: Correct. DNS tunneling (e.g., dnscat2, Iodine) is a stealthy method to bypass firewalls and extract sensitive data. * Option B (URL spidering) #: Would cause increased web traffic, not DNS requests. * Option C (HTML scraping) #: Involves parsing web pages, not DNS traffic. * Option D (DoS attack) #: DoS floods bandwidth or servers, but does not increase DNS queries significantly. # Reference: CompTIA PenTest+ PT0-003 Official Guide - DNS Tunneling & Data Exfiltration
