How to Recognize and Avoid Phishing Attacks

Understanding Phishing: The Digital Con Game

Phishing is a cybercrime where attackers impersonate legitimate organizations to steal sensitive information. In 2023, phishing was responsible for 36% of all data breaches, making it the most common attack vector.

The Psychology Behind Phishing

Phishing exploits human psychology through:

Urgency: "Your account will be closed in 24 hours!"
Authority: Impersonating banks, government, or IT departments
Fear: "Suspicious activity detected on your account"
Curiosity: "You've won!" or "Someone viewed your profile"
Helpfulness: "We're updating our security, please verify..."

Types of Phishing Attacks

1. Email Phishing

The most common type, using deceptive emails that appear to be from trusted sources.

Fake invoices or receipts
Account verification requests
Prize notifications
Security alerts

2. Spear Phishing

Targeted attacks using personal information to appear more credible.

References to your actual colleagues or projects
Uses information from social media (part of broader social engineering tactics)
Often targets specific departments (HR, Finance)

3. Whaling

Spear phishing aimed at high-profile targets like CEOs or CFOs.

4. Smishing (SMS Phishing)

Text message phishing, often with urgent delivery notifications or bank alerts.

5. Vishing (Voice Phishing)

Phone calls claiming to be from tech support, banks, or government agencies.

6. Clone Phishing

Duplicates of legitimate emails you've received, but with malicious links substituted.

Red Flags: How to Spot Phishing Attempts

Email Address Anomalies

Misspelled domains: amazom.com, mircosoft.com
Subdomain tricks: amazon.fake-site.com

Homograph attacks: Using similar-looking characters (rn vs m)

Content Red Flags

Generic greetings: "Dear Customer" instead of your name
Grammar and spelling errors: Professional organizations proofread
Urgent language: "Act now!" "Immediate action required!"
Threats: Account closure, legal action, arrest
Too good to be true: Unexpected prizes, refunds, or opportunities
Unusual requests: Asking for passwords, SSN, or payment info via email

Technical Indicators

Hover over links: Check if URLs match the supposed sender
HTTP vs HTTPS: Legitimate sites use HTTPS for sensitive data
Shortened URLs: bit.ly, tinyurl hiding the real destination
Attachment types: .exe, .zip, .scr files are often malicious
QR codes: Can hide malicious URLs
