Massive DDoS attacks on Dyn DNS cause outages at Twitter, Spotify, SoundCloud and other sites

Several waves of major cyberattacks against an internet directory service knocked dozens of popular websites offline yesterday, with outages continuing into the morning GMT +8 (Manila time).

Twitter, SoundCloud, Spotify, Shopify, and other websites have been inaccessible to many users throughout the day. The outages are the result of several distributed denial of service (DDoS) attacks on the DNS provider Dyn, the company confirmed. The outages were first reported on Hacker News.

“We are actively in the third flank of this attack,” Dyn’s chief strategy officer Kyle York told reporters around 4:30 p.m. ET today. “It’s a very smart attack. As we mitigate, they react.”

Dyn’s general counsel Dave Allen added that, with the help of other infrastructure companies Akamai and Flashpoint, Dyn has determined that some of the traffic used in the attacks comes from the Mirai botnet, a network of infected Internet of Things devices used in other recent large-scale DDoS attacks.

Dyn and other DNS providers operate as a link between the URLs you type into your browser and the corresponding IP addresses. DDoS attacks are frequently used to censor specific websites by overwhelming them with junk traffic and knocking them offline. However, by attacking Dyn, it’s possible to overwhelm that directory function and cause outages and loading problems across a large swath of the internet.

Other sites experiencing issues include Box, Boston Globe, New York Times, Github, Airbnb, Reddit, Freshbooks, Heroku and Vox Media properties. Users in Europe and Asia  (Symbianize) may experience fewer problems than those in the U.S. — according to DownDectector’s outage map, the DDoS attacks against Dyn are primarily impacting U.S. users.

The DDoS attacks on Dyn began yesterday morning. Service was temporarily restored around 9:30 a.m. ET, but a second attack began around noon, knocking sites offline once again.The DNS provider said engineers were working on “mitigating” the issue, but a third wave began around 4:30 p.m. ET before being resolved roughly two hours later.

At the moment, Dyn DNS is still dealing with the attack and its cause remains unknown.

The nation-wide internet outage was enabled thanks to a Mirai botnet that hacked into connected home devices, according to security intelligence company Flashpoint. 

Mirai is not a new hacking tool. A massive Mirai attack took down the site of popular security researcher Brian Krebs in late September, peaking at a nearly unprecedented 620 Gbps. 


Mirai takes advantage of weak security protocols on IoT devices -- in the Krebs case, 145,000 devices were infiltrated, including security cameras and DVRs in homes and offices around the world.

The author of the Mirai malware made its code open-source, and security experts have been warning of a possible large-scale attack since this information came to light.

If you’re experiencing connection problems, you can try changing your DNS settings (instructions for how to do this on Mac and Windows are here). Anecdotally, our staff has used OpenDNS (208.67.222.222 and 208.67.220.220) and OpenNIC servers and seen connectivity improve.
