Oleh Kret 8 min read April 10, 2026

Imagine living in a house with glass walls. Everything you do inside 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 Pineapple

Man-in-the-Middle (MitM)

Hacker becomes the "middleman" between you and the bank. They intercept and modify data on the fly.

> Bettercap

Packet Sniffing

Analysis of your traffic. If the site lacks HTTPS, the hacker sees passwords in plain text.

> Wireshark
The Solution: Premium VPNs use AES-256 encryption. They create an armored tunnel through which hackers see nothing but digital noise.
