A financial services company notices that their online banking platform becomes unresponsive during certain peak hours despite having no unusual activity from legitimate users. The IT team suspects a network-based attack designed to overwhelm their servers. Which type of attack are they most likely experiencing?
The correct answer is a Distributed Denial-of-Service (DDoS) attack. DDoS attacks aim to make an online service unavailable by overwhelming it with traffic from multiple sources, disrupting legitimate user access. Credential Replay involves reusing stolen credentials to gain unauthorized access, DNS Spoofing redirects traffic to malicious sites, and Wireless Eavesdropping intercepts wireless communications. None of these directly cause service unavailability through traffic overload.
