How Do Hackers Exploit Public Wi-Fi Networks?

Introduction

Every day in India, thousands connect to free café, airport, railway, and hotel Wi-Fi — and lose banking passwords, OTPs, and private photos in minutes. Public Wi-Fi is the easiest hunting ground for hackers. Our 8,000+ placed students at Ethical Hacking Training Institute & Webasha Technologies legally set up rogue access points daily in lab, perform live attacks, then teach banks, airports, and corporates how to stop them — earning ₹15–55 LPA at Deloitte, EY, Indian banks, and cybersecurity firms within months. 

Top 8 Public Wi-Fi Attacks Used Daily in India

• Evil Twin AP (fake “Starbucks WiFi” with stronger signal)
• Man-in-the-Middle (MITM) using ARP/DNS spoofing
• Packet sniffing with Wireshark/Airodump-ng
• Fake login portals (captive portal phishing)
• SSL stripping (https → http downgrade)
• Karma attack (auto-connect to known SSIDs)
• Rogue DHCP + fake DNS server
• Pineapple Wi-Fi (automated attack device)

How These Attacks Actually Work – Step by Step

We demonstrate every attack in our wireless lab exactly as criminals do it. Students set up Evil Twin with Fluxion/Bettercap, force victims to connect, capture all traffic, strip SSL, inject fake banking pages, steal OTPs, and even take full remote control. Then they immediately switch to defense mode and block the same attacks using enterprise WLC, RADIUS, and certificate pinning. This live red + blue team method is why our students never get hacked on public Wi-Fi again. 

Real Indian Cases We Teach From

• ₹28 lakh drained at Mumbai airport Wi-Fi
• Banking app hacked at Starbucks Delhi
• Entire family photos leaked at hotel Wi-Fi Goa
• Corporate employee lost ₹15 lakh at railway lounge
• Fake IRCTC portal stole tickets + payment details
• Student lost JEE admit card via café hotspot

These are real victim stories handled by our alumni.
