Editor's note: NordVPN (opens in new tab) and TorGuard have both published statements on their respective sites providing more details on the incident.
One of the world's most popular VPN providers has revealed it was hacked by an unidentified party following a major data breach.
Details are still scant but the virtual private network provider has confirmed one of its datacenters was penetrated in March 2018.
"A few months ago, we became aware of an incident in March 2018 when a server at a datacenter in Finland we had been renting servers from was accessed without authorization," the company wrote in a blog post. "This was done through an insecure remote management system account that the datacenter had added without our knowledge. The datacenter deleted the user accounts that the intruder had exploited rather than notify us."

While NordVPN has a “zero log” policy that was recently independently audited, one may question the motives of the hacker or hackers.
“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 blog added.
“On the same note, the only possible way to abuse the website traffic was by performing a personalized and complicated man-in-the-middle attack to intercept a single connection that tried to access NordVPN.”
"This was an isolated case, and no other servers or datacenter providers we use have been affected."
Two separate VPN issues
The hackers were able to identify an insecure remote management system that was operated by the datacenter provider and had full root access to a container server thanks to an expired TLS certificate.
In the own words of fellow hacker @hexdefined, this allowed “full control of everything in it (presumably including the ability to view and tamper with all network traffic going through it)”.
To make things even more interesting, two other VPN providers, access logs of VikingVPN and Torguard (opens in new tab) were also published alongside NordVPN on 8Chan, a possible indication that all three providers used the same data center.
