Examples of Cyber Attacks
Now we will consider some examples of cyber attacks that can be performed on different OSI model layers.
Layer 1 (Physical Layer)
Evil Twin Attacks: Attackers set up a rogue Wi-Fi hotspot with a similar name to a legitimate network to trick users into connecting.
Layer 2 (Data Link Layer):
ARP Spoofing/Poisoning: Attackers send false Address Resolution Protocol (ARP) messages to associate their MAC address with the IP address of a legitimate device.
An IP address (Internet Protocol address) is a numerical label assigned to each device in a computer network, serving as a unique identifier for communication. The key difference between an IP address and a MAC is that an IP address is assigned by the network, allowing devices to communicate across different networks, while a MAC address is a hardware identifier assigned by the device manufacturer.
Layer 3 (Network Layer):
IP Spoofing: Attackers send IP packets from a false (or "spoofed") source address to deceive the recipient about the origin of the message.
Layer 4 (Transport Layer):
- Man-in-the-Middle (MitM) Attacks: Attackers intercept and manipulate communication between two parties, often by eavesdropping or altering data in transit;
- Session Hijacking: Attackers steal session cookies or tokens to impersonate a user.
Layer 7 (Application Layer):
- SQL Injection: Attackers inject malicious SQL code into input fields, exploiting vulnerabilities in the application's database layer;
- Cross-Site Scripting (XSS): Malicious scripts are injected into web pages viewed by other users, typically through user inputs or unvalidated data;
- Cross-Site Request Forgery (CSRF): Unauthorized commands are transmitted from a user the web application trusts.
