Topic #: 1
[All 312-50v12 Questions]

In an advanced digital security scenario, a multinational enterprise is being targeted with a complex series of assaults aimed to disrupt operations, manipulate data integrity, and cause serious financial damage. As the Lead Cybersecurity Analyst with CEH and CISSP certifications, your responsibility is to correctly identify the specific type of attack based on the following indicators:

The attacks are exploiting a vulnerability in the target system's hardware, inducing misprediction of future instructions in a program's control flow. The attackers are strategically inducing the victim process to speculatively execute instructions sequences that would not have been executed in the absence of the misprediction, leading to subtle side effects. These side effects, which are observable from the shared state, are then utilized to infer the values of in-flight data.

What type of attack best describes this scenario?

  • A. Rowhammer Attack
  • B. Watering Hole Attack
  • C. Side-Channel Attack
  • D. Privilege Escalation Attack

Selected Answer: C
C. Side-Channel Attack In this context, the attackers are exploiting a vulnerability in the target system's hardware to observe and infer information based on side-channel information. The side-channel information, in this case, is derived from subtle side effects caused by speculatively executed instructions and mispredictions in the program's control flow.

Selected Answer: C
Explanation: The scenario describes an attack that exploits vulnerabilities in hardware by manipulating speculative execution and observing subtle side effects in shared state to infer sensitive data. This is characteristic of a side-channel attack, specifically a speculative execution attack such as Spectre or Meltdown.

Selected Answer: A
A: take advantage of side effect in DRAM hardware design B: induce victim to visit a malicious site C: gather extra information (such as timing information or power consumption), rather than directly exploit the target victim D: upgrade privilege to gain more access So the answer should be A.
