MiTM attack, often referred to as Man in the Middle or Monster in the Middle, pose a significant threat in the realm of cybersecurity. These malicious tactics involve intercepting and manipulating communication between two parties, allowing attackers to eavesdrop and tamper with messages undetected. Imagine it as the digital equivalent of the game of Telephone, where an unauthorized participant disrupts your conversation.
The objective of an MiTM attack is to illicitly acquire personal data, including login credentials and credit card information. Typically, the targets of such attacks are users of financial applications, e-commerce platforms, and other applications that necessitate user authentication. In this article, we shed light on the nature of MiTM attack and how they exploit vulnerabilities in communication channels.
How an MiTM Attack Typically Works
Interception: The attacker intercepts communication between two parties, making them believe they are communicating directly with each other.
Eavesdropping: The attacker can eavesdrop on the data being transmitted, collecting sensitive data such as passwords, credit card numbers, or other confidential data.
Modification: The attacker can alter the data being transmitted. For example, they might modify a legitimate message, redirect a user to a malicious website, or inject malware into the communication.
Impersonation: The attacker can impersonate one or both parties involved in the communication. This allows them to gain unauthorized access to systems or manipulate the communication for their benefit.
Common Techniques used in MiTM Attack
MITM attacks can occur in various forms, and they often target communication channels like Wi-Fi networks, email, web browsers, or any other method where data is transmitted between two or more parties. Here are some common techniques used in MiTM attacks:
Eavesdropping: The attacker intercepts data packets as they travel between the two legitimate parties, allowing them to monitor the communication.
Data Manipulation: The attacker can modify the data being exchanged between the two parties. For example, they can alter the content of emails, change URLs in web requests, or manipulate financial transactions.
Session Hijacking: Attackers may attempt to take control of an existing session between a user and a website. Potentially impersonating the user.
SSL Stripping: Attackers may try to downgrade secure HTTPS connections to unencrypted HTTP. Making it easier to intercept and manipulate data.
Rogue Access Points: Attackers set up rogue Wi-Fi access points with names similar to legitimate networks. Tricking users into connecting to the malicious network.
ARP Spoofing: Attackers manipulate Address Resolution Protocol (ARP) to associate their MAC address with the IP address of the target device. Diverting traffic through their system.
DNS Spoofing: Attackers can compromise the Domain Name System (DNS) to redirect users to malicious websites.
MiTM Attack and the Hardware-Based Approach
One particularly concerning variant of Man in The Middle attack is the hardware-based approach, leveraging rogue devices to infiltrate communication channels. These MiTM attack require physical access to tangible assets, such as Wi-Fi routers, network servers, or ATMs. Enabling cyber attackers to attach rogue devices and initiate their nefarious activities.
It’s important to be aware of notable MiTM attacks, such as the ATM Black Box attack. This hardware-based assault gained attention in 2017 and continues to pose a threat today. The Black Box attack involves connecting a rogue device directly to an ATM via USB ports, intercepting and manipulating communication between the ATM PC and the cash dispenser. The consequences can be devastating, as the attacker can command the machine to dispense cash, causing substantial financial losses (ATM Jackpotting Attacks).
The Importance of Physical Layer Visibility
Traditional security solutions often overlook the physical layer visibility of the OSI model, leaving devices vulnerable to Black Box attacks. This deficiency makes it crucial to adopt proactive measures that account for hardware-based attacks. Unfortunately, existing security solutions, such as NAC, IDS, EPS, and more, fail to cover, the physical layer visibility of the OSI model. As such, the rogue device goes undetected, leaving the ATM unprotected against Black Box attacks.
A 2023 report found that, in the first half of 2023, all but one logical attacks on ATMs were Black Box attacks. This caused losses of more than $500,000 (Black box attacks).
