Cookies were created to solve a problem, not to spy on you. Originally introduced in 1995, cookies enabled websites to remember user sessions, logins, shopping carts, and preferences—transforming static pages into dynamic, interactive experiences. While essential for modern web functionality, their misuse for tracking and ads has raised privacy concerns.

You Should Know:
1. How Cookies Work
Cookies are small text files stored in a user’s browser. They contain session data, authentication tokens, and user preferences.
Example HTTP Cookie Header:
[http]
Set-Cookie: sessionID=abc123; Expires=Wed, 30 Mar 2025 12:00:00 GMT; Secure; HttpOnly
[/http]
#### **2. Viewing Cookies in Browser**
- Chrome/Firefox:
- Press `F12` → Application → Cookies
- Terminal (Linux/Mac):
curl -I http://example.com | grep -i set-cookie
#### **3. Session Hijacking Prevention**
To mitigate cookie theft:
- Use Secure (HTTPS-only) and HttpOnly (block JavaScript access) flags.
- Implement SameSite attribute:
Set-Cookie: sessionID=xyz789; SameSite=Strict
#### **4. Managing Cookies via Command Line**
- Delete Cookies in Linux (Firefox):
rm ~/.mozilla/firefox/*.default-release/cookies.sqlite
- Check Cookies in Chrome (Linux):
sqlite3 ~/.config/google-chrome/Default/Cookies "SELECT * FROM cookies;"
#### **5. Testing Cookie Security**
Use OWASP ZAP or Burp Suite to analyze cookie vulnerabilities:
zap-cli --scan https://example.com
### **What Undercode Say:**
Cookies remain fundamental for web functionality but require strict security measures. Implement Secure, HttpOnly, and SameSite attributes to prevent hijacking. Regularly audit cookies using developer tools or CLI commands. For privacy, users should periodically clear cookies or use browser extensions like Cookie AutoDelete.
### **Expected Output:**
- Secure cookie configurations
- CLI-based cookie management
- Session hijacking countermeasures
