    • Phishing emails appear to come from a legitimate source, but aim to trick users into revealing private information.

    Spam

    • Spam is unwanted and unsolicited messages sent to a large number of people.

    Buffer Overflow

    • Buffer overflow occurs when a program tries to write more data into a buffer than it can hold, potentially leading to data corruption or system crashes.

    Keylogger

    • A keylogger records all the keys that a user types on a keyboard.

    Denial-of-Service (DoS) attack

    • The main goal of a DoS attack is to prevent legitimate users from accessing a service.

    Difference Between Viruses and Worms

    • The key difference is that viruses require human interaction, while worms can spread independently.

    Trojan Function

    • Trojans are designed to give an attacker unauthorized access to a system.

    Attackers Motivated by Political/Social Causes
