Cybersecurity Threats Quiz: Test Your Knowledge of Malware, Phishing, and DoS

📚 Quick Study Guide

• 🦠 Malware (Malicious Software): Includes viruses, worms, Trojans, ransomware, and spyware. It aims to harm or exploit any programmable device, service or network.
• 🎣 Phishing: A fraudulent attempt to obtain sensitive information such as usernames, passwords, and credit card details by disguising as a trustworthy entity.
• 🚫 Denial-of-Service (DoS) Attack: An attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic, or sending it information that triggers a crash.
• 🛡️ Defense Strategies: Use strong, unique passwords, enable multi-factor authentication (MFA), keep software updated, and be wary of suspicious emails and links.
• 🔥 Ransomware: A type of malware that encrypts a victim's files and demands a ransom to restore them.
• 🔑 Keylogger: A type of surveillance technology used to record every keystroke made by a user on a computer, often to steal passwords and other sensitive information.
• 💣 Botnet: A network of computers infected with malware, controlled by a single attacker (bot herder) without the owners' knowledge. Often used for DDoS attacks.
