Windows 10: NordVPN network hacked by third party provider breach

Brink · Oct 21, 2019

We understand the security concerns that arose from the information found online by security researchers and will address them in detail here.

A few months ago, we became aware that, on March 2018, one of the datacenters in Finland we had been renting our servers from was accessed with no authorization. The attacker gained access to the server by exploiting an insecure remote management system left by the datacenter provider while we were unaware that such a system existed. The server itself did not contain any user activity logs; none of our applications send user-created credentials for authentication, so usernames and passwords couldn’t have been intercepted either. The exact configuration file found on the internet by security researchers ceased to exist on March 5, 2018. This was an isolated case, and no other datacenter providers we use have been affected.

Once we found out about the incident, we immediately launched a thorough internal audit to check our entire infrastructure. We double-checked that no other server could possibly be exploited this way and started creating a process to move all of our servers to RAM, which is to be completed next year. We have also raised the bar for all datacenters we work with. Now, before signing up with them, we make sure that they meet even higher standards.

When we learned about the vulnerability the datacenter had a few months back, we immediately terminated the contract with the server provider and shredded all the servers we had been renting from them. We did not disclose the exploit immediately because we had to make sure that none of our infrastructure could be prone to similar issues. This couldn’t be done quickly due to the huge amount of servers and the complexity of our infrastructure.

The timeline is as follows: the affected server was built and added to our server list on January 31, 2018. The data center noticed the vulnerability they had left and deleted the remote management account without notifying us on March 20, 2018. Our techs found that the server provider had had the undisclosed account a few months ago. We then immediately took action to audit our entire server network and accelerated the encryption of all of our servers.

The expired TLS key was taken at the same time the datacenter was exploited. However, the key couldn’t possibly have been used to decrypt the VPN traffic of any other server. On the same note, the only possible way to abuse website traffic was by performing a personalized and complicated MiTM attack to intercept a single connection that tried to access nordvpn.com.

To recap, in early 2018, one isolated datacenter in Finland was accessed without authorization. That was done by exploiting a vulnerability of one of our server providers that hadn’t been disclosed to us. No user credentials have been intercepted. No other server on our network has been affected. The affected server does not exist anymore and the contract with the server provider has been terminated.

Even though only 1 of more than 3000 servers we had at the time was affected, we are not trying to undermine the severity of the issue. We failed by contracting an unreliable server provider and should have done better to ensure the security of our customers. We are taking all the necessary means to enhance our security. We have undergone an application security audit, are working on a second no-logs audit right now, and are preparing a bug bounty program. We will give our all to maximize the security of every aspect of our service, and next year we will launch an independent external audit all of our infrastructure to make sure we did not miss anything else.

With this incident, we learned important lessons about security, communication, and marketing.

Did our Epson printer get hacked?

Another question, is this on a home network or a work network? The steps @eidairaman1 listed are always a good first step. If this is on a work network you manage, I'd be much more concerned than the home one. It is possible someone is screwing with you, but malware could also be the culprit.

Good LAN party games?

Most of my suggestions have already been listed.

However, I found Swat4 to actually be a pretty fun LAN game, especially at smaller LAN parties.

Windows 10 infinite restart black screen

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.
