What is Phishing?
Phishing is a type of cybercrime where attackers disguise themselves as trustworthy entities to steal sensitive information such as usernames, passwords, and credit card details. This deceptive practice has evolved significantly since its emergence in the 1990s, becoming increasingly sophisticated and challenging to detect. The term "phishing" is a play on the word "fishing," as attackers are essentially "fishing" for victims' information.
Common Types of Phishing Attacks
- Email Phishing: The most traditional form, involving fraudulent emails that appear to be from reputable sources
- Spear Phishing: Targeted attacks aimed at specific individuals or organizations
- Whaling: Attacks specifically targeting high-profile executives
- Smishing: Phishing conducted through SMS messages
- Clone Phishing: Attackers create nearly identical copies of legitimate emails, replacing original links with malicious ones
- Vishing: Voice-based phishing attacks using phone calls
How Phishing Works
Phishing attacks often start with a deceptive message that creates a sense of urgency or panic, prompting the recipient to act quickly without verifying the authenticity of the request. These messages can be highly sophisticated, mimicking the branding and tone of well-known companies or institutions.
Red Flags to Watch For
- Urgent or threatening language
- Generic greetings (e.g., "Dear Sir/Madam")
- Suspicious sender addresses
- Poor grammar and spelling
- Requests for sensitive information
- Unexpected attachments
- Unusual requests for passwords or credit card numbers
Protection Strategies
Technical Safeguards
- Two-factor authentication
- Email filtering software
- Up-to-date antivirus protection
- Web browsers with built-in phishing protection
- VPN usage, especially on public Wi-Fi
