🎯 The Fundamental Principle

"Trust No One" is a fundamental principle in cybersecurity. This doesn't mean being paranoid, but rather always verify before trusting.

// Basic principle in cybersecurity
if (source.isUnknown() || request.isSuspicious()) {
    return verify() && doubleCheck() && askExpert();
} else {
    return stillBeCareful();
}
            

⚠️ Golden Rule

Always verify the identity of your contact before sharing sensitive information, even if this person claims to be someone you know.

🎭 Why Does This Principle Exist?

1. Social Engineering

Cybercriminals exploit the natural trust of humans. They pretend to be:

Your bank - "We need to verify your account"
A friend in distress - "I lost my phone, can you help me?"
Technical support - "Your computer is infected"
A colleague/boss - "It's urgent, send me your credentials"

2. The Ease of Identity Theft

On the Internet, it's extremely easy to:

Create a fake profile with your photo
Spoof an email address
Copy the appearance of an official site
Imitate someone's tone and style

🛡️ How to Apply "Trust No One"

Systematic Verifications

Verify URLs of websites (https, correct domain)
Contact directly the person through another means
Be wary of urgency - real services don't rush you
Check email addresses (typos, suspicious domains)
Never click on suspicious links

💡 Concrete Example

Your "friend" sends you a message: "Hi! I have a problem with my account, can you lend me $50 via PayPal?"

Security reflex: Call your friend directly to verify. In 90% of scam cases, the real friend knows nothing about it!

🎪 Real Example: This Troll Page

You just lived a perfect example! You clicked on a mysterious button that led you to a page that:

Retrieved your real IP address
Detected your browser and system
Tried to locate you geographically
Made you believe a "hack" was in progress

🎯 The Lesson

This page was harmless and created for educational purposes. But imagine if it was a real trap with malicious intentions!

Before clicking on an unknown link, always ask yourself: "Do I trust this source?"

🚨 Warning Signs

Be suspicious when asked for:

Passwords or access codes
Banking information "for verification"
Personal documents (ID card, etc.)
To act quickly under pressure
To keep it secret about the request

Typical scammer phrases:

"Your account will be closed in 24h if..."
"Congratulations! You have won..."
"Urgent problem with your account..."
"Don't tell anyone, but..."
"Click here immediately to..."
