A DDoS (Distributed Denial-of-Service) attack is a cyberattack that overwhelms a website, server, or network with a massive flood of fake internet traffic from multiple compromised devices (a botnet) to make it slow, unresponsive, or crash, preventing legitimate users from accessing the service. It's like a massive traffic jam on a digital highway, clogging resources like bandwidth, CPU, and RAM so real users can't get through. Attackers use these to disrupt services, steal business, extort money, or damage reputations.
