يواجه مستخدمو الانترنت حول العالم - خصوصاً في الولايات المتحدة - صعوباتٍ في دخول المواقع الالكترونية الرئيسية.

وبحسب موقع Business Insider، فقد تعرضت أهم مواقع العالم لهجوم DDoS الذي يستهدف DNS، وهي أهم فقرة في منظومة الانترنت، إذ تعمل على تترجم عنوان الموقع إلى عنوان IP.

أبرز المواقع الرئيسية المعطلة، هي Amazon وTwitter وEtsy Github وSpotify، وما زالت شبكة المواقع المعطلة حالياً في توسّع.

وحتى الآن لا يُعرف من وراء هجوم DDoS، لكن بحسب موقع The Next Web، فإن قدرتهم على اختراق المواقع الكبرى تدل على الإمكانيات العالية للمهاجمين.

الهجوم الالكتروني طال بشدة مدن الساحل الشرقي للولايات المتحدة، وأشارت شركة Dyn المزودة بالـ DNS، إلى أنها رصدت هجوم DDoS على بنيتها التحتية التي تدير نظام أسماء النطاقات في الساعة 11:10 UTC بالتوقيت العالمي، وأنها تحاول صد وتخفيف حدة الهجوم.

وتحدثت “الشبكة العربية للأخبار التقنية” عن أنباء عن الإطاحة بنصف شبكة الانترنت العالمية اليوم.



ويبدو أن قائمة المواقع المتضررة تزداد، وفيما يلي قائمة المواقع التي قد يواجه المستخدمون صعوبة في الوصول إليها، ويبدو أن المشكلة تزداد سوءاً:

The outage is said to be mainly affecting the US East Coast. Internet infrastructure provider Dyn said this was due to an ongoing interruption of its network.

  • Github, Airbnb, SoundCloud and PayPal also reported to be down
  • Outage appears to be primarily affecting web users on the US East Coast 
  • The ongoing interruption of its network resulting from a DDoS attack
  • DDoS attacks are a primitive form of hacking using botnets - networks of computers that hackers bring under their control 

 

Major internet services, including Twitter and Spotify, suffered outages today as a US internet provider came under cyber attack.

The internet service company Dyn said that it had suffered a denial of service (DDoS) attack on its domain name service shortly after 6AM ET (11AM BST).

The outages mostly affected the east coast of the US, and many services were restored in about two hours. However, some sites are still experiencing problems.

WHAT IS A DDOS ATTACK?

DDoS attacks are a primitive form of hacking using botnets - networks of computers that hackers bring under their control.

They do this by getting users to inadvertently download software, typically by following a link in an email or agreeing to download a corrupted file.

These botnets are then used to bombard the servers with simple requests for information carried out simultaneously, causing them to become overwhelmed and shut down. 

Amazon was also investigating outage reports, CNBC reported.

Some US internet users had trouble accessing sites including Twitter and Vox, but others found the sites accessible in Europe or via mobile phones. 

Other sites experiencing issues include Github, Airbnb and Reddit.

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. 

The level of disruption caused was hard to gauge, but Dyn provides internet traffic optimisation to some of the biggest names on the web.

This morning, October 21, Dyn received a global DDoS attack on our Managed DNS infrastructure in the east coast of the United States, said Scott Hilton, executive vice president for products at Dyn, in a statement.

DNS traffic resolved from east coast name server locations are experiencing a service degradation or intermittent interruption during this time, Hilton added.

We have been aggressively mitigating the DDoS attack against our infrastructure.

Twitter users were quick to comment on the widespread outage. You know its going to be a fun day when you wake up to a ton of alert emails saying everything is broken, said one user

The attack, which started today, impacted websites hosted by the domain company DYN. According to the OCD Tech twitter account, there are 173,831 domains hosted on DYN name servers

The attack was first reported on website Hacker News, which named social media giant Twitter along with music service Spotify among a list of sites down.

O-M-G… Twitter is down.Thats what you may have heard many of your friends, family members and work colleagues saying today if they were based in the US and some other parts of the world, said Lee Munson, security researcher for Comparitech.com.

The reason being, online criminals have once again gone after a significant site with a DDoS attack.

Not Twitter, or other popular and equally affected sites such as Spotify, Reddit, Github and SoundCloud though, but rather DNS provider Dyn.

And that highlights a problem – any company running its own website may well have its own technology in place to mitigate DDoS attacks, but its all for nought if the DNS provider itself is not applying a sufficient enough level of protection to its own servers and data centres.

Users in the UK have been mostly unaffected by the issue.

Commenting on this, Richard Meeus, VP technology EMEA at NSFOCUS, a DDoS mitigation company, said: DNS has often been neglected in terms of its security and availability from an enterprise perspective – it is treated as if it will always be there in the same way that water comes out of the tap and electricity is there when you switch it on. 

This attack highlights how critical DNS is to maintaining a stable and secure internet presence, and that the DDOS mitigation processes businesses have in place are just as relevant to their DNS service as it is to the web servers and datacentres.  

Reports suggest that some of the affected websites have since improved in reliability. 

An FBI representative said she had no immediate comment on the outages.

Dyn is a Manchester, New Hampshire-based provider of Internet infrastructure services, including managing DNS activity that connects a user to a websites servers.

Some Twitter users mocked the attacks. Someone named Gorman created a Mean Girls meme (pictured) making fun of the widespread nature of the attack

David Gibson, VP of strategy and market development at Varonis saidL "Like many of our aging technologies, DNS wasn’t built with security in mind. 

Unfortunately, DNS is a foundation technology for the internet that allows people to connect to internet resources with human names rather than IP addresses (think of them as internet phone numbers), and when its vulnerabilities are exploited attackers can do a lot of damage – computers don’t know which “phone number” to call when you want to connect to a particular site, like Hacker News. 

DNS is one of the aging technologies the industry is struggling to update, along with one-factor authentication (password-only security), unencrypted web connections – the list is very long, and the stakes have never been higher. 

Many people and organisations are affected by today’s attack and by the email and file (e.g. video) leaks over the past couple months.
