Data security is extremely important in today's digital world, as each one of us relies very heavily on the Internet for communication, shopping, banking, and much more. Man-in-the-middle (MITM) is probably one of the most dangerous cybersecurity threats. That kind of attack style allows hackers to secretly intercept your data, and that should give hackers control for manipulation purposes as well, where your network security and online privacy are in direct danger. What are MITM attacks? What exactly do they do? We'll discuss them more throughout this blog, including the steps for how a person could effectively protect themselves.
A Man-in-the-Middle attack occurs when a hacker secretly inserts himself between two parties who are communicating with each other. Think of it as sending a letter to a friend, but someone secretly opens it, reads it, changes its contents, and then reseals it before sending it on. That is what happens in an MITM attack but with digital data.
Hackers use this approach to acquire private information, such as a password, a credit card number, or private messages. In addition, hackers can change the data sent, which may lead to severe impacts, such as a hacker modifying details of the money transfer that one is conducting so that it can be directed into his/her account.
Here's a step-by-step breakdown of how an MITM attack happens:
There are quite a few methods that hackers could use to achieve MITM attacks. Here are the most commonly used methods among them:
MITM attacks do not exist merely in the imaginary realm; instead, they do take place and cause disastrous impacts. Here are a few instances:
The good news is that there are a few things you can do to protect yourself from MITM attacks and online privacy. Here are some practical tips:
One of the best techniques applied to prevent interception is encryption. Ensure all the sites you access are using HTTPS. Sometimes, it is even easy to find it, given that you'll look for a lock icon on the left side of the URL when opening it with your browser. Encryption will hence make the data sent from your browser to the website unreadable to hackers.
Hackers target public Wi-Fi networks. Access one's bank accounts and mail by email using the bank Wi-Fi. Use VPN encryption on the Internet to protect the network.
Most hackers attack the old versions of software, so keep an eye on regular updates for the operating system, browser, and apps to lower the risk of MITM attacks.
Two-factor authentication is another security layer added to your accounts. They won't be able to access your account even if they intercept your password because there's another step to be identified, for instance, an SMS confirmation code that's sent to your phone.
Hackers tend to send phishing emails or fake websites that might make you surrender your sensitive information. Always verify the URLs and never click on a suspicious link.
A firewall will definitely prevent illegal access to your network. So, it is another protection level against MITM attacks.
The more you watch over your accounts, emails, and other online accounts, the faster you can identify suspicious activities occurring. The sooner a breach is detected, the quicker one can act to limit the breach.
While individuals can do their part, businesses have a responsibility to protect the data of their customers. Here's what organizations can do:
One of the protections for data that may get intercepted is through Encryption. In that case, your data will be encrypted to form a coded form that is readable to someone with a correct decryption key. There are several types of Encryption used to protect data:
Using very powerful encryption technology can greatly minimize the chances of 'data interception' while safeguarding your online privacy.
Some methods used by hackers continue to evolve with advances in technology by which they execute their MITM assaults. However, cybersecurity keeps changing, and answers to prevent this type of danger come about. Here are a few trends:
Man-in-the-middle attacks are one of the major cyber threats that can breach your online privacy and network security. Understanding how these attacks take place and then taking preventive measures against such cyber attacks can considerably reduce the possibility of data interception. Remember, you must always encrypt your information, avoid using public Wi-Fi, update your software, and always be aware of phishing attacks. Be it an individual or a business entity, cyber security has become essential in the current digital era.
