Mirai is a notorious malware that infects Internet of Things (IoT) devices, such as cameras and routers, by exploiting weak security settings. Once compromised, these devices become part of a botnet - a network of remotely controlled systems - that can be used to launch massive Distributed Denial of Service (DDoS) attacks. These attacks overwhelm targeted websites or online services, causing them to slow down or become unavailable. Mirai gained global attention in 2016 after being used in several high-profile attacks. Variants like Aisuru have since emerged, offering even more advanced capabilities.
