A man-in-the-middle attack represents a cyberattack in which a malicious player inserts himself into a conversation between two parties, I want to receive news and product emails. However, these are intended for legitimate information security professionals who perform penetration tests for a living. Man-in-the-middle attacks come in two forms, one that involves physical proximity to the intended target, and another that involves malicious software, or malware. A successful attacker is able to inject commands into terminal session, to modify data in transit, or to steal data. You can learn more about such risks here. These attacks can be easily automated, says SANS Institutes Ullrich. Imagine you and a colleague are communicating via a secure messaging platform.

The Google security team believe the address bar is the most important security indicator in modern browsers. At first glance, that may not sound like much until one realizes that millions of records may be compromised in a single data breach. Domain Name Server, or DNS, spoofing is a technique that forces a user to a fake website rather than the real one the user intends to visit. Periodically, it would take over HTTP connection being routed through it, fail to pass the traffic onto the destination and respond as the intended server. The best countermeasure against man-in-the-middle attacks is to prevent them. Prevention is better than trying to remediate after an attack, especially an attack that is so hard to spot. An attacker cant decode the encrypted data sent between two computers communicating over an encrypted HTTPS connection. Successful MITM execution has two distinct phases: interception and decryption. They might include a bot generating believable text messages, impersonating a person's voice on a call, or spoofing an entire communications system to scrape data the attacker thinks is important from participants' devices.
