Computer Hacking Forensic Investigator (CHFI v10) — Question 534

Which network attack is described by the following statement? "At least five Russian major banks came under a continuous hacker attack, although online client services were not disrupted. The attack came from a wide-scale botnet involving at least 24,000 computers, located in 30 countries."

Answer options

• A. Man-in-the-Middle Attack
• B. Sniffer Attack
• C. Buffer Overflow
• D. DDoS

Correct answer: D

Explanation

The correct answer is DDoS (Distributed Denial of Service), as it involves overwhelming a target with traffic from a large number of compromised devices, which aligns with the botnet described. The other options, such as Man-in-the-Middle Attack and Sniffer Attack, focus on intercepting or manipulating data rather than overwhelming services, and Buffer Overflow pertains to exploiting vulnerabilities in software rather than network disruption.
