NordVPN, a virtual private network provider, has confirmed it was hacked in March 2018, with one of its data centers in Finland being accessed without authorization. The attacker exploited an insecure remote management system left by the data center provider, but NordVPN claims that no user activity logs were stored on the server and that the breach did not affect other servers on its network. The company only disclosed the breach after being sure that its infrastructure was secure. The hack has raised concerns about the potential access to user data and the security of VPN providers.
