Inside Mirai, the Hack that Broke the Internet

In October 2016, a malware tool named Mirai took down some of the biggest sites and services on the web, including Netflix, Spotify, Twitter, PayPal, and Slack. The blackout affected most of the East Coast of the United States, and the size and scope of the outage alarmed the cybersecurity researchers and law enforcement agencies tasked with thwarting such attacks. The code that caused this meltdown was created by three individuals, all in their teens or early 20s. The trio had built a tool that took control of internet-connected smart home devices and used them—like a massive zombie army—to knock the internet’s most vital servers offline. Now, years later, Mirai’s three creators have told their story.

This week, we talk to WIRED senior writer Andy Greenberg about Mirai’s creation, how the code did its damage, and how the three hackers were eventually caught.
