    Mirai is a self-propagating malware that scans the internet for vulnerable IoT devices and infects them to create a botnet. Mirai variants utilize lists of common default credentials to gain access to devices. Mirai's primary use is for launching distributed denial-of-service (DDoS) attacks, but it has also been used for cryptocurrency mining.
