How to Protect Yourself from Man-in-the-Middle Attacks: Tips for Safer Communication
Man-in-the-middle (MITM) attacks are a type of cyberattack where a malicious actor intercepts communications between two parties in order to secretly access sensitive data or inject false information. While MITM attacks can be difficult to detect, there are some steps you can take to protect yourself.
For example, always verifying the identity of the person you’re communicating with and using encrypted communication tools whenever possible. Additionally, it’s important to be aware of common signs that an attack may be happening, such as unexpected messages or requests for sensitive information.
Man-in-the-middle attacks are one of the most common types of cyberattacks. MITM attacks can allow the attacker to gain access to sensitive information, such as passwords or financial data. Man-in-the-middle attacks can be very difficult to detect, but there are some steps you can take to protect yourself. First, be aware of the warning signs of a man-in-the-middle attack. These include:
– unexpected changes in login pages,
– unexpected requests for personal information,
– and unusual account activity.
If you see any of these warning signs, do not enter any sensitive information and contact the company or individual involved immediately. Second, use strong security measures, such as two-factor authentication, to protect your accounts. This will make it more difficult for attackers to gain access to your information. Finally, keep your software and operating system up to date with the latest security patches. This will help to close any potential vulnerabilities that could be exploited by attackers.
Man-in-the-middle attacks can be devastating for individuals and businesses alike. By intercepting communications between two parties, attackers can gain access to sensitive information or even impersonate one of the parties involved. Fortunately, there are a number of steps you can take to protect yourself from man-in-the-middle attacks.
- First, avoid using public Wi-Fi networks for sensitive transactions. Attackers can easily set up their own rogue networks, and it can be difficult to tell the difference between a legitimate network and a malicious one. If you must use public Wi-Fi, be sure to use a VPN to encrypt your traffic.
- Second, be cautious about the links you click on. When in doubt, hover over a link to see where it will actually take you. And always be suspicious of links that come from untrustworthy sources.
- Finally, keep your software and security tools up to date. Man-in-the-middle attacks are constantly evolving, so it’s important to have the latest defenses in place.
By following these simple tips, you can help keep yourself safe from man-in-the-middle attacks.
HTTPS (or really, SSL) is specifically designed to thwart MITM attacks.
Web browsers validate that both the certificate presented by the server is labeled correctly with the website’s domain name and that it has a chain of trust back to a well-known certificate authority. Under normal circumstances, this is enough to prevent anyone from impersonating the website.
As the question points out, you can thwart this by somehow acquiring the secret key for the existing website’s certificate.
You can also launch a MITM attack by getting one of the well-known certificate authorities to issue you a certificate with the domain name of the website you wish to impersonate. This can be (and has been) accomplished by social engineering and hacking into the registrars.
Outside of those two main methods, you would have to rely upon bugs in the SSL protocol or its implementations (of which a few have been discovered over the years).
What are the countermeasures of MITM?
For the web, we use a similar principle. A certificate is a specific document issued by a third party that validate the identity of a website. Your PC can ask the third party if the certificate is correct, and only if it is allow the traffic. This is what HTTPs does.
Man In The Middle attacks are carried out because an attacker is in between both communicators (let’s say two clients or a client and a server). If he is able to see the communication in clear text, he can do a whole lot ranging from stealing login credentials to snooping on conversations. If encryption is implemented, the attacker would see gibberish and “un-understandable” text instead.
In terms of web communication, digital certificates would do a great job of encrypting communication stream (any website using HTTPS encrypts communication stream by default). For social media apps like whats app and Skype, it is the responsibility of the vendor to implement encryption.
MitM Attack Techniques and Types

- Email Hijacking
- Wifi Eavesdropping
- Cookie Stealing and so on.
Can MITM attacks steal credit card information?
When you enter your sensitive information on an HTTP website and press that “Send” button, all your private details travel in plain text from your web browser to the destination server.
A cyber-attacker can employ a man-in-the-middle attack and intercept your information. Since it’s not encrypted, the hacker can see everything: your name, physical address, card numbers, and anything else you entered.
To avoid MITM attacks, don’t share your info on HTTP sites. More on SSL certificates and man-in-the-middle attacks in this detailed medium article
How common are MITM attacks in public places with free WIFI?
Not common by people, but common by malware and other software that are designed to do that.
How do you ensure your RDP is secure from MITM attacks?
- Make sure all of your workstations and remote servers are patched.
- On highly sensitive devices, use two-factor authentication.
- Reduce the number of remote account users with elevated privileges on the server.
- Make a safe password.
- Your credentials should not be saved in your RDP register.
- Remove the RDP file from your computer.
