A renowned research institute with a high-security wireless network recently encountered an advanced cyber attack.

[Reference: NIST SP 800-153, Guidelines for Securing Wireless Local Area Networks (WLANs)., Bypassing Security Measures:, Even with WPA3 encryption, MAC address filtering, and disabled SSID broadcasting, an Evil Twin can trick users into connecting by mimicking the legitimate network’s SSID and signal strength., Reference: CIS Controls, Control 13 - Network Monitoring and Defense., Stealth and Detection:, The attack can be performed without noticeable disruption to the network, as the rogue AP simply relays traffic to the legitimate network, making it hard to detect through traditional measures., Reference: IEEE 802.11 Standards and Best Practices., Forensic Analysis:, Forensic analysis revealing the method indicates that sophisticated techniques were used to capture and exfiltrate data without triggering security alarms., Reference: ENISA’s Guidelines on Incident Response and Management., Given the described security environment and the nature of the attack, an Evil Twin Attack is the most likely method used., , ]
