✓ Pros

  • VPNs offer 100% protection against MitM
  • HTTPS everywhere makes it harder for hackers

✗ Cons

  • People forget to turn VPNs on
  • Rogue networks are hard to identify visually

The Cafe Trap

You sit down, order a latte, and connect to 'Starbucks_Free_WiFi'. What you might not know is that the guy in the corner is running a Man-in-the-Middle (MitM) attack.

How MitM Attacks Work

Hackers set up rogue hotspots with identical names. When you connect, your traffic routes through their machine. While HTTPS protects most passwords, DNS queries and unencrypted sites are fully exposed.

Defense Strategies

1. **Always use a VPN:** It encrypts the tunnel, making interception useless.
2. **Never install certificates:** If a network asks you to install a profile to connect, leave immediately.
3. **Turn off auto-connect:** Prevent your phone from silently connecting to familiar-sounding networks.
