Hackers can eavesdrop and intercept your internet traffic and then use it to gain access to your accounts and online profiles. While this might sound like a plot from an action movie, it’s exactly what a replay attack is all about. What are the common methods in replay attacks, and how can you protect yourself?
In order to launch a replay attack, criminals have to gain access to your network, so they can eavesdrop on your internet data. There are several ways to achieve this, but usually hackers implant malware on the victim’s device or set a fake hotspot, which they can control remotely. A replay attack is a more specific type of man-in-the-middle-attack, so they share some similarities.
In a replay attack, a hacker intercepts your data and resends the same web request to a server, so it looks like that data is coming from your browser. When the server sends back a response, the hacker will receive it. But what type of data attracts hackers?
Let’s say you want to log into your account on social media, internet forum, or any other website. You type your login credentials into a website and then your browser sends the username and the password hash to the corresponding server. If an attacker intercepts your password hash and session ID, he can initiate a new session and pretend to be you. All of this can be done without the server having any idea that they’ve been attacked.
Since hackers can resend messages over the network without decrypting them, it’s easy to trick the receiver that this message is authentic.
Replay attacks can do a lot of damage to both individuals and businesses, but with certain measures, it’s possible to fight them. Here are a few ways to enhance your security for replay attack prevention.
If you’re experiencing any signs of malware infection, it might be the first warning that someone is eavesdropping on your traffic. While successfully preventing replay attacks depends on your server, there are a few things you can do to improve your cyber hygiene and avoid falling prey to hackers.
