Mirai malware targets loT devices. After infiltration, it uses them to propagate and create botnets that then used to launch which types of attack?

The correct answer is C. DDoS attack. Mirai malware infiltrates IoT devices to create botnets, which are primarily used to launch large-scale Distributed Denial of Service (DDoS) attacks.

Why each option

Mirai malware infiltrates IoT devices to create botnets, which are primarily used to launch large-scale Distributed Denial of Service (DDoS) attacks.

AMITM attack

A MITM (Man-in-the-Middle) attack involves intercepting communication between two parties, which is not the primary function of Mirai botnets.

BBirthday attack

A Birthday attack is a cryptographic attack exploiting the mathematics behind the birthday problem to find collisions in hash functions, which is unrelated to botnet functionality.

CDDoS attackCorrect

Mirai malware is infamous for compromising vulnerable IoT devices, such as routers and IP cameras, turning them into a botnet. These botnets are then orchestrated to launch massive Distributed Denial of Service (DDoS) attacks against targeted websites or services, overwhelming them with traffic and rendering them unavailable.

DPassword attack

Password attacks involve guessing or cracking passwords to gain unauthorized access, which is the initial infection vector for Mirai, not the attack launched by the resulting botnet.
