Fake Wi-Fi access point that mimics a legitimate network to intercept users' traffic and credentials.
An evil twin is a rogue Wi-Fi access point configured to appear identical to a legitimate network—same name (SSID) and often stronger signal. Users connecting to the evil twin believe they're on the real network, but all their traffic passes through the attacker's equipment. Attackers can capture credentials, inject malware, perform MitM attacks, or redirect users to phishing sites. Evil twin attacks are common in public spaces where people expect free Wi-Fi—coffee shops, airports, hotels.
Why It Matters
The DSC Perspective:
Evil twin attacks make public Wi-Fi risky. Users should avoid sensitive activities on public networks or use VPN/mobile data instead. Corporate policies should require VPN for remote work on untrusted networks.
