Phishing is a trick where scammers send fake emails or messages to steal your passwords or personal details. They often pretend to be a trusted brand or a friend to make you click a harmful link.

Phishing: Don't take the bait!

Other major threats include malware, which is bad software that damages devices, and identity theft, where someone steals your personal info to pretend to be you. Strong passwords help stop these password attacks.

✏️ Worked example

Analyze this real-world scenario: You receive an urgent text message from an unknown number. It says: 'Your bank account is locked! Click this link instantly to verify your password or lose your funds.' Explain how to identify the specific cybersecurity problems in this message and decide what action to take.

  1. Identify the delivery method: The message arrived as an unexpected, urgent text message from a completely unknown number.
  2. Analyze the language used: Look for high-pressure words like 'instantly' and threats like 'lose your funds,' which are classic signs of a scam.
  3. Spot the specific threats: The request to click a link to verify a password is a classic 'phishing' attack trying to perform a 'password attack' or commit 'identity theft'.
  4. Evaluate the safety risk: Real banks do not ask you to click random text links to unlock accounts or reveal passwords.
  5. Formulate the final safe action: Do not click the link. Block the sender number immediately and report the message as spam.
