As clouds gather in the public and private sectors, the Internet of Things (IoT) – and all the devices it brings – has organized into a hurricane-sized force that challenges evolving security strategies. Earlier this year, researchers developed a Stuxnet-like malware proof-of-concept attack which they claimed could infiltrate critical infrastructure and potentially disrupt the power grid.
The attacks, however, didn’t target power plants or energy producing facilities, but instead focused on leveraging high-wattage IoT devices such as air conditioners and heaters to cause sudden generation tripping, disrupt grid restarts, line failures, cascades, and increase demand from the systems, all of which could result in outages or even blackouts, according to the “BlackIoT: IoT Botnet of High Wattage Devices Can Disrupt the Power Grid” report.
The attacks highlight the growing threat IoT devices can provide and the need for resilient and pervasive cloud security to protect the networks often tasked with operating these devices.
