This is done by forging a large number of ARP request packets. An attacker’s MAC address is linked with the IP address of a legitimate user on a LAN. ARP spoofing:ĪRP (Address Resolution Protocol) is a stateless protocol which is used to resolve IP addresses to physical MAC (media access control) addresses in a local area network. There are various techniques such as IP spoofing and DNS cache poisoning for implementing a MITM attack, but for the scope of this article, we will look at an implementation ARP spoofing attack using Kali Linux OS and Wireshark packet analyzer. This security breach exploits real-time transactions and conversations by intercepting data that is meant to be secure and it is usually too late by the time either of the affected party realises what has transpired. Other than websites, a Man-in-the-Middle (MITM) attack can happen in any form of online communication such as email, DNS lookups, social media and so on. Generally speaking, the goal is to steal sensitive information by targeting vulnerable websites or stealing cookies. In brief, malicious users intercept the data flowing on a user’s machine or a server and can listen to every piece of information being passed through the network. Hackers can have various end goals for launching this attack, they may either silently observe data packets or impersonate a user and modify the data they send or receive. The attackers usually insert themselves between a conversation, usually occurring among a web server and an application. Man – in – the – middle – attack is a very common type of cyber attack which involves eavesdropping on a network connection.
