Risks of Connecting to Malicious Hotspots (Evil Twin Attacks)
A particularly cunning threat on public Wi-Fi is the “evil twin” attack. In this scenario, hackers create a fake Wi-Fi network that mimics the name of a legitimate one.
For instance, a cybercriminal might set up a network called “CoffeeShop_WiFi_Free,” which appears almost identical to the real network offered by a café.
Unsuspecting users connect to this fake network, thinking it’s safe. However, the moment they do, all their online activity is routed through the hacker’s device.
This allows the attacker to steal sensitive data like login credentials, credit card details, or personal emails.
How can you avoid falling victim to an evil twin attack?
- Verify the network name with the establishment before connecting.
- Avoid networks that don’t require a password or have suspicious names.
- Use a VPN to add an extra layer of security, even if you accidentally connect to a malicious hotspot.
