A renowned research institute with a high-security wireless network recently encountered an advanced cyber attack. The attack was not detected by traditional security measures and resulted in significant data exfiltration. The wireless network was equipped with WPA3 encryption, MAC address filtering, and had disabled SSID broadcasting. Intriguingly. the attack occurred without any noticeable disruption or changes in network performance. After an exhaustive forensic analysis, the cybersecurity team pinpointed the attack method. Which of the following wireless network-specific attacks was most likely used?

• A. KRACK (Key Reinstallation Attack), exploiting vulnerabilities in the WPA2 protocol
• B. Jamming Attack, disrupting network communications with interference signals
• C. Evil Twin Attack, where a rogue access point mimics a legitimate one to capture network traffic
• D. Bluesnarfing. exploiting Bluetooth connections to access network data

Stephen, a security professional at an organization, was instructed to implement security measures that prevent corporate data leakage on employees' mobile devices. For this purpose, he employed a technique using which all personal and corporate data are isolated on an employee's mobile device. Using this technique, corporate applications do not have any control of or communication with the private applications or data of the employees.
Which of the following techniques has Stephen implemented in the above scenario?

• A. Geofencing
• B. Full device encryption
• C. OTA updates
• D. Containerization
