Phishing

Phishing is a social engineering technique where a malicious person sends an email, text or instant message that looks and sounds legitimate in order to compel users into taking a specific action.Many phishing attempts are designed to lure users into providing confidential information such as a username, password, social security number, bank account number or a PIN.One of the most common methods of phishing is via email. A phishing email may ask a user to click on a link to verify their account information, open an attachment to view an e-card, document, or message, or verify their username and password by replying to the email. The following are clues of some common characteristics associated with phishing emails:
  • The email is addressed to a generic recipient.
  • The email projects urgency, prompting the user for immediate action.
  • The email contains an embedded link behind another link or text.
  • The email subject line is uninformative and doesn’t reflect the message content.
  • The email doesn't include an informative signature.
  • The email prompts you for username and password or other sensitive information.
