Do Hackers Have Any Chance Of Hacking VPNs? All About Vpn Security

# Do Hackers Have Any Chance Of Hacking VPNs? All About Vpn Security :

Can Hackers Hack VPNs? How will it affect you as a user of this service?

Well, we will answer these questions by taking a live example documented of a real hacking case of one of the best VPNs out there in 2018, NordVPN.

What can the NordVpn hack tell us about VPN security?

The answer is, yes, VPNs can be hacked, but it really cannot be considered a direct hack or hack of service servers.

Do hackers have any chance of hacking VPNs? All About Vpn Security

Hackers know that brute force hacking for VPN encryption is useless, however, they exploit some vulnerabilities that exist within the VPN network and whose security is not often updated, so a hacker may succeed in discovering a crossing point inside the network . 

NordVPN is a good example of a vulnerability that was exploited in third-party servers, because it is configured incorrectly or does not have the necessary protection against a possible hack, so the physical VPN server will become an easy target for hackers. 

The breach on NordVPN's servers was due to a vulnerability discovered by a hacker in a server located in a Finnish data center, but due to the company's policy of not keeping any user logs, no sensitive user passwords were exposed. 

After discovering the security breach, NordVPN implemented new security measures, including server upgrades to RAM-only servers, comprehensive security audits, and installation of troubleshooting software.

Is NordVPN safe after these updates?

The answer is yes, and the evidence is that it occupies one of the first positions in the list of the 5 best VPN services on the Internet, and this was evident in their taking very strict measures to avoid any future hacking operations, and this is a sufficient reason to use this service comfortably. 

However, not all VPNs can afford maintenance and high-level security improvements, especially when it comes to the core aspect of a VPN, as hackers don't hack into the server, but look for holes in direct connections.

Can a VPN be hacked while online?

Usually this is not possible, but it is very likely that there are some VPNs that still use old tunneling protocols that contain a great security weakness, and therefore they will be exploited during the connection and used as a port to access the server. 

At the moment there are several protocols in use, which are still considered a weak, like as PPTP which is very weak and easy to break, L2TP and SSTP which are vulnerable to man-in-the-middle attacks.

Do VPNs still use this type of protocol?

Many weak private networks that do not bear maintenance costs still use this type of protocol, but for strong companies, very modern and powerful protocols have been supported in their servers such as IKEv2, OpenVPN, and WireGuard, which are considered more secure and reliable. 

There are also private protocols like NordVPN's NordLynx or ExpressVPN's LightWay.

Are these modern protocols secure when connected?

Very safe? This is because of the high level of encryption that is built into these modern protocols, usually, starting with a key length of 128Bit, it is really difficult to crack this encryption, in the cases of AES-256 and ChaCha20 encryption we would say it is very impossible for a crack to occur. 

So far, no network or service has been hacked when using AES-259 encryption, but despite this, a leak may occur during the connection, as it is possible to leak the IP address of your device if the VPN does not encrypt IPv6 requests from your browser. 

Also, IPv4 leaks can happen if you are using an untrusted VPN or a free VPN service, as well as DNS leaks when your ISP ends up managing your DNS requests instead of the VPN service.

Are solutions to these leaks provided by VPN service providers?

Most reputable companies are aware of these leaks, so they provide with their services solutions and protection for any leakage that may occur, in addition to providing keys to lock this leakage or the so-called Kill Switch, which is an important feature that prevents any leakage that may occur during a network outage or connection instability. 

How do we know this VPN is good?

I believe that the VPN, which provides the following options, is a very secure and reliable network

  • Top-grade encryption
  • Audited no-log policy
  • Reliable protocols
  • kill switch
  • Diskless servers
  • Leak protection
  • Bug bounty program

Therefore, the availability of these features on the VPN will greatly increase the user's security and give him great comfort while browsing the Internet or using applications.
