Introduction
Jude is at the airport, waiting for his flight back home. He realizes that he missed making an important bank payment while he was away. He decides to use his laptop and the public wifi at the airport to carry out the transaction. Little did he know, this decision would lead to trouble.
The Cyber Attack
Jude goes ahead with the bank transaction and everything seems to go well. He completes the transaction successfully. However, a couple of days later, he realizes that a hefty amount has been wiped from his bank account. Panicked, he gets in touch with the bank authority and learns that his account was hacked. He also realizes that using the public wifi at the airport might have caused this trouble.
The Need for a VPN
Jude wishes he had used a VPN to secure his bank transfer and escape the eyes of the hackers. The bank officials advise him to use a VPN for future transactions, especially when connecting to open public networks like the one at the airport.
Understanding VPN and Its Importance
Jude has come across the term VPN several times but didn’t know much about it. He didn’t realize the repercussions of using a VPN and how it could have prevented the cyber attack on his bank account. Let’s understand how a hacker would have exploited Jude’s transaction in the absence of a VPN.
When Jude’s computer first connects to the internet, the internet service provider (ISP) provides access through the IP address. The details are sent to the bank server using this IP address. Without a VPN, the internet details pass through the public network, and a hacker can passively watch the network traffic and intercept the data. In a passive cyber attack, the hacker collects Jude’s bank details without being detected. The payment information is likely to be stolen, along with other targeted data like usernames, passwords, and personal information.
How a VPN Protects Your Data
In the presence of a VPN, the situation is different. When Jude uses a VPN, the first step is to install a software-based technology known as a VPN client on his laptop or smartphone. This client allows him to establish a secure connection. The VPN client connects to the wifi through the ISP and encrypts Jude’s information using VPN protocols. This encryption ensures that the data remains secure.
Next, the VPN client establishes a VPN tunnel within the public network. It connects to a VPN server, and this VPN tunnel protects Jude’s information from being intercepted by a hacker. The hacker cannot see Jude’s actual IP address or location because it is hidden by the VPN.
Finally, the VPN server connects Jude’s device to the bank server. In this last step, the encrypted message is decrypted, but the hacker cannot trace it back to Jude’s original IP address. The VPN creates a private and secure connection for the transaction.
The Advantages of Using a VPN
Using a VPN not only makes your data anonymous and secure when passing through a public network, but it also provides other benefits. For example, VPNs can be used to disguise your whereabouts and give you access to regional web content. VPN servers act as proxies on the internet, so your actual location cannot be established. It enables you to spoof your location, making it appear as though you are in another country. For example, if you want to watch content on Netflix that might be unavailable in your region, a VPN can help you access it.
Conclusion
Given the current rise in cyber attacks, it is crucial to stay alert and protect your digital information. Using a VPN is a safe and effective way to secure your bank transactions, especially when connecting to public wifi networks like the one at the airport. In addition to providing a secure and encrypted data transfer, VPNs also allow you to disguise your location and access regional web content. Consider using a VPN for all your online transactions and stay one step ahead of cyber criminals.
