According to a report recently published by the security firm Corero the number of DDoS Attacks doubled in the First Half of 2017 due to unsecured IoT. The longest DDoS attack in Q4 2016 lasted for 292 hours (or 12.2 days) significantly longer than the previous quarters maximum (184 hours, or 7.7 days) and set a record for 2016. Cyber crime is fueled by profit motives now, it is safe to assume that the cyber criminals have figured out how to monetize the IoT threat.”]
