Brace yourselves. The rest of the media is going to be calling this an “IoT DDOS” and the hype will spin out of control. Hype aside, the facts on the ground make it look like an extremely large distributed denial-of-service attack (DDOS) was just carried out using mostly household appliances (145,607 of them!) rather than grandma’s old Win XP system running on Pentiums.

We can argue all day about whether a digital video recorder (DVR) or an IP webcam is an “IoT” device and whether this DDOS attack is the biggest to date or merely among them, but the class of devices exploited certainly are not traditional computers, and this is a big hit. Most of these devices run firmware out of flash, and it’s up to the end user (who is not a sysadmin) to keep it up to date or face the wrath of hackers. And it’s certainly the case that as more Internet-facing devices get deployed, the hacker’s attack surface will grow.

Why did the DDOS network use these particular devices? We’re speculating, but we’d guess it’s a combination of difficult-to-update firmware and user “convenience” features like uPnP. To quote the FBI “The UPnP describes the process when a device remotely connects and communicates on a network automatically without authentication.” You can see how this would be good for both the non-tech-savvy and hostile attackers, right? (Turn off UPnP on your router now.)

We alternate between Jekyll and Hyde on the IoT. On one hand, we love having everything in our own home hooked up to our local WiFi network and running on Python scripts. On the other hand, connecting each and every device up to the broader Internet and keeping it secure would be a system administration headache. Average users want the convenience of the latter without having to pay the setup and know-how costs of the former. Right now, they’re left out in the cold. And their toasters are taking down ISPs.
