There’s a reason why most people feel uncomfortable about the idea of someone eavesdropping on them—the eavesdropper could possibly overhear sensitive or private information. This is exactly the risk that computer users face with a common threat called a “Man-in-the-Middle” (MITM) attack, where an attacker uses technological tools, such as malware, to intercept the information you send to a website, or even via your email.
Just imagine you are entering login and financial details on an online banking site, and because the attacker is eavesdropping, they can gain access to your information and use it to access your account, or even steal your identity.
There are a variety of ways that attackers can insert themselves in the middle of your online communications. One common form of this attack involves cybercriminals distributing malware that gives them access to a user’s web browser and the information being sent to various websites.
