How To Prevent From Replay Attack? (New Methods)


Thanks to digital technologies, life has become more accessible. However, this advancement has opened us up to cyberattacks and data breaches. This article will discuss what a replay attack is and how to prevent it.


Discussion Started:

A replay attack occurs when a cybercriminal enters a secured network. They intercept it and redirect the receiver to do what the hacker wants by resending or delaying communication. The main risk with a replay attack is that the attacker doesn’t own the advanced skills necessary for decrypting messages captured from the network. They can resend the complete message to the server impersonating the sender.


Frequently Asked Questions:

Q1. What are the types of replay attacks?

The different types of replay attacks are session, man-in-the-middle, pre-play, denial-of-service, digest access authentication, telephone tapping, and relay attack.

Q2. What are active attacks?

Active attack is an attack on the network, where the hacker changes the data on the way to the target. Cybercriminals mostly take malicious actions on the device containing the information somehow.

Q3. What is the difference between a man-in-the-middle attack and a replay attack?

In simple words, a man-in-the-middle attack manipulates the existing network packets or creates new network packets. In contrast, a replay attack would steal legitimate traffic or information from a source and then use it at another time without any changes.


Here are some Explanation:

Point 1: Suppose a third party intercepts a data transmission and then replays it. This act would allow them to interact with the transmission receiver by pretending to be the original sender. Such a threat is a replay attack. Simply put, a replay attack is a type of cyber attack where the task being performed or a request being made by a user is repeated or replayed because a third party has intercepted the data exchange. This third party is stealing valuable information by triggering the exchange again while pretending to be the original sender or recipient of the request.
It is one of the simplest types of cyberattacks today, and countless people fall prey to it every day.

Point 2: Replay attacks enable hackers to break into data exchanges happening over the networks by imitating the sending party. Once they hack into the data exchange, the interceptor or hacker can replay it in the same form that they intercepted it in. Thus, they can steal valuable information in the exchange.

Under this section we want to understand what a replay attack is and how it works with an example. 

Suppose you are trying to log into a website. You type in your username and password, hit Enter, and wait for the dashboard to load up. However, a third-party – a hacker, breaks into this data exchange and imitates the website entity. They replay the data exchange for you, making you log into the website again by typing in your username and password.
You think there was some issue with the network and innocently key in your login credentials. The website thinks the login is being requested again and processes it.


The user and the website don’t realize that the hacker had intercepted the data exchange and stolen your login credentials. This act is what is a replay attack. Here, your data exchange got replayed, and then information got stolen.

Example on how and way your data could get stolen by a replay attack.
 
Hackers can use replay attacks to steal other sensitive and valuable information, making it essential to prevent them. However, passwords and login credentials remain the most common thing stolen by replay attacks.

Now you know what a replay attack is and how it can cause a cosmic loss to you. It is necessary to prevent replay attacks and safeguard yourself. 

Next section, let’s find out what measures can be taken to avoid it.

How do you prevent replay attacks?


Many organizations implement several replay attack prevention methods and network security. But they need more robust solutions to prevent such fraudulent events.

The most crucial thing is the right encryption. Encrypted messages are generally opened with a key or a decoded code. But a replay attack need not read the message and resend it as a whole accompanied by a key.

Replay attack prevention methods include: 


There are some simple steps you can follow for replay attack prevention, such as:

Method 1: Insist on using one-time passwords or OTPs for logging in. If you face a replay attack situation, you will still get a new OTP once the hacker replays the data exchange. Your login credentials, as well as the information after login, would be safe.

Method 2: Attach timestamps with defined short time limits can prevent replay attacks and safeguard your data.

Method 3: Always insist on accessing websites using the HTTPS protocol. The HTTPS protocol is the secure protocol. You can adjust the settings in your browser to prevent opening any websites that do not support the HTTPS protocol. This approach will enable replay attack prevention.

Method 4:Avoid using public Wi-Fi or free Wi-Fi connections when accessing websites requiring sensitive information.

The most important Method: – use a VPN or a Virtual Private Network whenever possible to safeguard your data and prevent replay attacks.
