What is a Phishing Attack?

Phishing is a cybercrime where attackers impersonate legitimate entities to trick victims into sharing confidential information. They often use fake emails, websites, or messages designed to look authentic, exploiting human trust and urgency.

Types of Phishing Attacks

1. Email Phishing

Attackers send bulk emails designed to mimic trusted institutions like banks or online platforms. These emails often include links to fake websites or malicious attachments.

2. Spear Phishing

Unlike generic phishing, spear phishing targets specific individuals or organizations. These messages are personalized, making them more convincing.

3. Whaling

A type of phishing that targets high-profile individuals such as executives or government officials. These attacks often involve detailed and sophisticated scams.

4. Smishing (SMS Phishing)

Phishing via text messages that include malicious links or requests for sensitive information.

5. Vishing (Voice Phishing)

Attackers use phone calls to impersonate trusted entities, such as tech support or government agencies, to steal information.

6. Clone Phishing

Attackers duplicate a legitimate email, modify it with malicious links or attachments, and resend it to the victim.

7. Pharming

This involves redirecting users from legitimate websites to fake ones, often without their knowledge, to steal sensitive data.

How Phishing Works

1. Bait: A fake email, message, or website is sent to the victim.
2. Hook: The victim is persuaded to click on a link or download an attachment.
3. Catch: The victim unknowingly provides sensitive information, like login credentials or payment details.

Signs of a Phishing Attempt

• Suspicious Email Addresses: Check for misspelled or strange email domains.
• Urgency or Fear Tactics: Phrases like “Act Now” or “Your account will be suspended.”
• Generic Greetings: Emails that begin with “Dear Customer” instead of your name.
• Misspellings and Poor Grammar: Legitimate organizations rarely send emails with errors.
• Unfamiliar Links: Hover over links to verify their destination before clicking.
