The Anatomy of Invisibility: How VPN Really Works?
Imagine living in a house with glass walls. Everything you do inside — reading the paper, talking to family, counting money — is visible to passersby.
When you connect without protection, your traffic passes through many nodes: neighbor's router, ISP equipment, backbone servers. At each stage, "glass walls" allow others to see where you go and what you do.

2. Anatomy of an Attack: Tools & Methods
Here are real tools hackers use against you in public Wi-Fi networks:
Fake Hotspot (Evil Twin)
Hacker creates a network named "Free_WiFi". Your phone connects automatically because the signal is stronger.
> WiFi PineappleMan-in-the-Middle (MitM)
Hacker becomes the "middleman" between you and the bank. They intercept and modify data on the fly.
> BettercapPacket Sniffing
Analysis of your traffic. If the site lacks HTTPS, the hacker sees passwords in plain text.
> WiresharkSession Hijacking
Stealing cookie files. Hacker enters your Facebook without login and password.
