Phishing

From Encyclopedia of Cybersecurity

Phishing

Phishing is a form of cybercrime in which attackers attempt to deceive individuals into disclosing sensitive information, such as usernames, passwords, credit card numbers, or other personal information, by impersonating a trustworthy entity. Phishing attacks commonly take the form of deceptive emails, instant messages, or websites that appear to be from legitimate sources, such as banks, social media platforms, or government agencies.

Operation

Phishing attacks typically involve the following steps:

  1. Bait: Attackers create and distribute deceptive communications, such as emails or messages, that lure recipients into taking a specific action, such as clicking on a malicious link or providing sensitive information.
  2. Deception: The communications are carefully crafted to appear as though they are from a legitimate source, often using logos, branding, and language that mimics the trusted entity.
  3. Exploitation: When recipients fall for the deception and take the desired action, attackers exploit their trust to steal sensitive information or deploy malware onto their devices.
  4. Payload: In some cases, phishing attacks may deliver malware, such as ransomware or keyloggers, which can compromise the security and privacy of the victim's device and data.

Mitigation

To protect against phishing attacks, individuals and organizations can take several preventive measures:

  • Education: Raise awareness among users about the risks and characteristics of phishing attacks through training and awareness programs.
  • Vigilance: Encourage users to be cautious when interacting with unsolicited emails, messages, or websites, especially those requesting sensitive information or urgent action.
  • Verification: Advise users to verify the legitimacy of communications by independently verifying the sender's identity, using contact information from trusted sources rather than clicking on links or responding directly to messages.
  • Technology: Implement email filtering and anti-phishing tools to detect and block suspicious communications, and use multi-factor authentication to enhance security.
  • Reporting: Establish procedures for reporting suspected phishing attempts to IT or security teams for investigation and response.
