Why botnets used in DDos attack?

Botnets are used in DDoS attacks because they leverage a large network of compromised devices to overwhelm a target with traffic. By coordinating many devices, attackers can generate massive volumes of requests that exceed the target's bandwidth or server capacity. This distributed nature makes it difficult to mitigate the attack, as the traffic originates from numerous locations, masking the source and complicating defense strategies. Moreover, botnets can be easily rented or sold on the dark web, making them accessible for malicious actors.
