What is an Evil Twin Attack?
An evil twin attack is a type of Wi-Fi security threat where a malicious actor creates a rogue wireless access point that mimics a legitimate one. This tactic is designed to deceive users into connecting to the fake network instead of the legitimate one.
How It Works
In an evil twin attack, the attacker sets up a Wi-Fi network with a similar name (SSID) to a legitimate network, often within range of unsuspecting users. When users connect to this malicious network, the attacker can intercept any data transmitted, such as passwords, credit card numbers, and personal information.
Common Tactics
- SSID Spoofing: The attacker uses the same network name as the legitimate access point.
- Signal Strength Manipulation: The rogue network is configured to have a stronger signal, making it more attractive to users.
- Packet Sniffing: Once connected, the attacker can capture data packets sent across the network.
Prevention Measures
To avoid falling victim to evil twin attacks, users should:
- Use a VPN when connecting to public Wi-Fi.
- Verify the network name with staff in public areas.
- Disable automatic connections to open networks.
By understanding and recognizing the signs of an evil twin attack, individuals can better protect their sensitive information and maintain their wireless security.
