  • 🦠 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.
  • πŸ›‘οΈ Defense Strategies: Use strong, unique passwords, enable multi-factor authentication (MFA), keep software updated, and be wary of suspicious emails and links.
  • πŸ”₯ Ransomware: A type of malware that encrypts a victim's files and demands a ransom to restore them.
  • πŸ”‘ 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.
