The most concerned issue in this digital world is cyber security. But when it comes to network security we have blind faith on VPN. VPN has become the backbone of many business and IT company. The worst part is that VPN is no more secure. The threats related to Virtual Private Networking or VPN are increasing.
The urge of using a VPN has raised incredibly. According to Global Mobile VPN Report 2019, over 480 million mobile VPN applications have been downloaded in the past 12 months. Though the recent events of contradiction in VPN provider’s network have raised questions about security. So we need to know the risks related to VPN.

Threats Affecting VPN Service
Before we dive into our topic, we should know how VPN provides security to us. When we search or visit a website, it gets our IP address. But with VPN, We first get connected to one of the VPN servers and then directed to the websites. So no one can get your IP address. In a nutshell, the real work of a VPN is to hide your real IP address.
But recent events of vulnerability in some VPNs are alarming. Attackers have succeeded to breach NordVPN, a renowned VPN provider along with two other VPN providers- TorGuard and VikingVPN. Simply these have raised questions on the threats that are affecting VPNs.
So in this section, we will know about the top 5 threats affecting VPN service. Here we go:
1. MITM Attacks
VPN mainly use single layer protections. They encrypt user’s IP address. There is no additional level of security. Once this single-layer protection is broken, criminals can access your information.
For example, “Man in the middle attackers” can enter in the communication channel between the user and application. They even can listen up your conversation or modify your network traffic without your permission.
The MITM appears so genuine that the user hardly doubts anything. This Cyber thief attacks mainly to steal your password, de-anonymize you and to serve you virus.
VPN may protect you from such an attack but not necessary all the time. VPN may fail to provide security if all the users of a particular website are attacked.
2. Weak Security Protocol
Many VPN services are using weak security protocols that risk the information of the users. Most of the VPNs using five security protocols.
- PPTP (Point to Point Tunnelling Protocol) was built in the mid-1990s.But now it is declared unsafe.
- L2TP is another old protocol that do not provide any encryption. Hence not that secure
- Even IKEv2 is no more trustworthy protocol. It was warned that NSA can break its encryption.
As experts considered them unsecure, OpenVPN and Wireguard are the two choices left. Even Wireguard is not completed now.
3. Authentication Bypass
Criminals can find their way to attack your information. Such a gateway is authentication. Often the attackers can access the assets behind the VPN. As a result, important data become available to the criminal.
Usually, this occurs due to the flaws in the VPN. These flaws allow the criminal to get the resources without user’s authentication.
Pulse Secure declared such threats in its products –Pulse Connect Secure and Pulse Policy secure. They are found to allow attackers to use a specific URL, as a result, the criminal gets access to the files on the destination network.
4. Weaponized HTTPS
HTTPS is a basic tool for safe surfing. But it now can be used by criminals. They mainly use it as a gateway to access your data. Usually, they develop specific HTTPS and use it to bypass authentication. Once it is done, the criminal can access data from the network.
They are often designed to serve worms. Worms can spread and replicate much faster. When it comes to the machine they can be easily infected. A machine can be infected if a user connects to a infected networks. These infections can be Trojans, riskware and spyware programs.
5.Brute Force attack
Another threat is “Distributed Denial Service Attack” or “Brute Force attack”. This can mess up the VPN service. The continuous logging in attempts by attackers can end up by giving access to the information. They can get into your company’s network system and get the passwords.
The reason for such attacks is weak encryption. Most of the VPN services come with Weak algorithms. From DES to BDES, SHA1 and RSA have flaws. These flaws in algorithms are raising more dangers to VPN services.
However, the modern world is full of risks. You should be very careful about your activities. The vulnerability of VPN services may rise day by day. So be aware of what is happening in the digital world. Keep your antivirus and other apps always updated. Hope the text will help you to secure your data.
