Some cyberattacks are simply not possible using blockchain, but data volume and storage are challenges for the technology. The internet had its own “October surprise” when DVR and IP cameras were infected with malware and created a massive outage that took down Twitter, Reddit, The New York Times, PayPal and other major websites. The malware targeted Internet of Things (IoT) devices such as routers, digital video recorders, and webcams/security cameras. Experts fear this may only be the beginning, and with millions of devices across the IoT, the internet remains vulnerable.
