Interception can happen in several ways, including:
1. Packet Sniffing: Hackers use tools to capture data packets transmitted over a network. 2. Man-in-the-Middle Attacks: An attacker intercepts and possibly alters the communication between the sender and receiver. 3. Phishing: Fraudulent emails designed to trick recipients into revealing sensitive information. 4. Malware: Malicious software that can intercept and manipulate email communications.
