So Who Turned Off Half the Internet?
On Oct. 21, the U.S. east coast dealt with a massive online attack that affected access to some of the Internet’s most popular sites, including Amazon, Netflix, Spotify, and Paypal. Just what happened — and can we expect a similar disruption (or worse) in the future?
The trouble started when Dyn, a company that monitors and routes Internet traffic, was hit with a major distributed denial of service (DDoS) attack that flooded its servers with enough requests to crash the system.
This attack was compounded by the increasingly-present Internet of Things: requests from millions of unique Internet-accessible devices infected with the malware Mirai, which allows infiltrators to gain access to everything from remote cameras to DVRs to some kitchen appliances.
These infected devices created a robot network (botnet) that overwhelmed Dyn’s servers for hours before they could recover. As of this writing, the culprits are still unknown.
Threats like this aren’t going away – in fact, as this attack has shown, between Internet-connected devices and rudimentary malware, they’re getting easier to perform in larger volume. You need to be at the top of your game to understand such threats and protect your organization against them, and DRI’s IT/DR Planning workshop is a great place to start.
