Nearly three years after the Mirai distributed denial-of-service (DDoS) attacks, the danger to corporate networks from insecure consumer Internet of Things (IoT) devices appears to have grown.

Computers and phones were excluded from the IoT classification in the study.
Disturbingly, millions of the devices in the Avast study were found to have security weaknesses such as open services, weak default credentials, and vulnerabilities to known attacks.
