MITM Attacks

MITM attacks

MITM attacks, 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 attacks 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 attacks and how they exploit vulnerabilities in communication channels.

The Hardware-Based Approach

One particularly concerning variant of Man in the Middle Attacks is the hardware-based approach, leveraging rogue devices to infiltrate communication channels. These MITM attacks 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.

The Importance of Physical Layer Visibility to Prevent MITM Attacks

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 MITM threats.

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 2021 report found that, in the first half of 2021, all but one logical attacks on ATMs were Black Box attacks. This caused losses of more than $500,000 (ATM explosive attacks in Europe rise again).
