last night, the us Internet users were virtually cut off from their favorite sites. At one point, services like Netflix, Amazon, PayPal, Imgur, Pinterest, Twitter, Airbnb, Spotify,, as well as websites such as the New York Times, HBO stopped working for many hours. Polish users of the problem felt to a small degree. However, this does not change the fact that yesterday was held one of the largest attacks in Internet history.
what was the attack
Criminals attacked one of the most sensitive points of the infrastructure: servers, DNS. Play a key role in the network, because I explain ‘ websites into IP addresses. Thanks to them, we can type in browser name gazeta.pl instead ‘ 80.252.0.145. Paralysis of DNS servers does not allow, so that work sites and applications.

Attack the “Internet of things”
Dyn, a company that attacked the DNS servers, admitted that part of a DDoS attack has occurred through a variety of devices connected to the network. The ecosystem of web-cameras, sensors, controllers in General called “Internet of things” was used by offenders as a botnet – a network of zombie computers. Still, this role was performed mainly on computers.
the Existence of a new type of botnet was confirmed a month ago. It controls the malicious software called Mirai, explains the Huffington Post.

Attack on Dyn recalls, so in a sense, the previous attack, in particular, to customers of OVH. And they can attack through Webcams.
Experts warn that someone is testing as to paralyze the Internet
Yesterday’s incident happened according to the experts, a specific purpose. Someone explores the threshold of endurance of companies managing the infrastructure of the Internet. Yesterday’s attack was a test of strength of the enemy.
DDoS Attacks are not for anybody a surprise and major DNS servers was their purpose. Now, however, the attacks look different. Their aim is not the fastest possible shutdown of servers through the blockage they share or depletion of processing power. Seizures are usually designed to test how the scale of the danger will cope administrators. [...] Attacked the company must use all your protective mechanisms, at the time, to stop the attackers.
- explain the experts of a Trusted Third Party.
“is Used 10 percent of capacity”
we are also Concerned about the statements of some Western experts. Dale drew, CEO of Telecom company Level 3 believes that the worst may occur.
the attack uses only ten percent of the nodes controlled by the software Mirai. The number of these devices is constantly expanding.
– he said in an interview with Yahoo.
Bruce Schneier, an expert in cybersecurity, who was the first to warn about what is happening something exciting has a bad feeling.
Who is behind this? Activists, criminals, researchers? Profiling the basic infrastructure of the state, as a rule, the work of spies and intelligence. The company do not. In addition, the size and scale of the attacks give reason to suspect that they stand for forces of any state. It reminds me of the cold war, sending planes to the Soviet Union in order to verify their air defense system to test its capabilities.
writes in the author’s blog.
So, even if yesterday’s attack did not give tired a bad Polish, it does not mean that next time we can get away with it.
fortunately, other experts say that full blocking of the Internet, more likely, will fail. The attack can last many hours, maybe days. But global and complete blocking of the network, and even more durable, it seems unlikely.
Complete shutdown of the Internet in principle is not possible. Successful attacks on DNS servers complicates or even makes impossible the use of specific services on the Internet. On the other hand, it means the inability to use of the Internet for end users.
, – concluded the conversation with us Robert paszkiewicz, Director of Sales and Marketing at OVH. He said at the same time, what to make of the whole network can only be achieved through an attack on a large number of DNS servers scattered around the world. This requires considerable resources.
vigilant
Yesterday’s attack, he could be the first phase of the upcoming cyberwojny. Mirai can be no less complex software than the notorious Stuxnet.
it is Possible that China or Russia will examine how to paralyze the Internet. Or to cut off US citizens from digital services. Maybe it’s just the call of chaos, the occurrence of losses at U.S. technology giants. It could be a prelude to something much more terrible?
About how actually, we learn only when will come the next attack. But it is inevitable. Nobody knows, but when and what will be the power and purpose of the shot.
on Saturday have restored the normal functioning DNS servers.
