Cyber attacks disrupt Twitter, Netflix, other sites

LONDON — A massive cyber attack caused dozens of popular websites to basically shut down Friday after a key firm was hit by a cyberattack.

It all started around 8:30 a.m. Chicago time when New Hampshire-based Dyn said its server infrastructure was hit by a distributed denial-of-service attack, which works by overwhelming targeted machines with malicious electronic traffic.

Dyn is kind of a phone book for websites, so when you type in an address it navigates you to that site.  What the hackers do is send so many requests for sites that it can’t keep up so essentially it shuts everything down. The company said in a series of statements that the attack took place early Friday local time and created disruption, but that "services have been restored to normal."

The level of disruption caused was hard to gauge, but Dyn provides internet traffic optimization to some of the biggest names on the web. Some of the big companies hit were Twitter, Pay Pal Airbnb, Spotify and more. Several sites, such as coder hangout Github, said they were experiencing problems, although it was not immediately clear whether the issues were linked to the cyberattack.

Some some of the sites impacted by this attack are back online, possibly running a little slower, but they are coming up.

This is a relatively new way hackers are using to attack Internet companies, and it’s hard to recover from.  This one came in two waves and may not be over.

Several security agencies in the Federal government, including the Department of Homeland Security, are investigating because of the large scale of the attack, though it may be hard to figure out who is behind the attack unless someone takes credit for it.
