Question 144

Disrupt control flow to modify instructions

B.

Observe hardware signals to deduce secrets

C.

Crack hashes using statistical collisions

D.

Force session resets through input flooding

Question 145

A retail brand based in San Diego, California, authorized a controlled mobile security exercise to evaluate risks associated with third-party application distribution channels. Testers acquired a version of the company ' s customer rewards application from an unofficial marketplace frequently used by overseas customers. The application ' s visual layout and functionality were indistinguishable from the officially released version available in mainstream app stores. Behavioral monitoring conducted in a sandbox environment revealed that, in addition to its normal operations, the application initiated outbound connections unrelated to its documented features. A binary comparison against the vendor-supplied build confirmed structural differences between the two versions. What mobile-based social engineering technique does this scenario most accurately represent?

Options:

A.

Repackaging Legitimate Apps after modifying their internal structure

B.

Publishing Malicious Apps designed to mimic trusted brands

C.

Conducting SMiShing campaigns through fraudulent text messages

D.

Deploying Fake Security Applications disguised as protection tools

Discussion
Question 146

A security analyst is tasked with gathering detailed information about an organization ' s network infrastructure without making any direct contact that could be logged or trigger alarms. Which method should the analyst use to obtain this information covertly?

Options:

A.

Examine leaked documents or data dumps related to the organization

B.

Use network mapping tools to scan the organization ' s IP range

C.

Initiate social engineering attacks to elicit information from employees

D.

Perform a DNS brute-force attack to discover subdomains

Question 147

During a red team assessment of an enterprise LAN environment, the tester discovers an access switch that connects multiple internal workstations. The switch has no port security measures in place. To silently intercept communication between different hosts without deploying ARP poisoning or modifying the routing table, the tester launches a MAC flooding attack using the macof utility from the dsniff suite. This command sends thousands of Ethernet frames per minute, each with random, spoofed source MAC addresses. Soon after the flooding begins, the tester puts their network interface into promiscuous mode and starts capturing packets. They observe unicast traffic between internal machines appearing in their packet sniffer—traffic that should have been isolated. What internal switch behavior is responsible for this sudden exposure of isolated traffic?

Options:

A.

The switch performed ARP spoofing to misroute packets.

B.

The switch entered hub-like behavior due to a full CAM table.

C.

The interface performed DHCP starvation to capture broadcasts.

D.

The switch disabled MAC filtering due to duplicate address conflicts.
