Which tool is a network traffic sniffer app with SSL decryption using MITM techniques, capable of capturing and decrypting SSL traffic and displaying packets in hex or text?

• A. Analytic plug-ins
• B. Capsa Network Analyzer
• C. Sniffer Wicap
• D. FaceNiff

Answer: (D)

Understanding SSL/TLS interception is key here: to inspect encrypted traffic, you need to perform a man-in-the-middle interception so the tool can decrypt the data and show it in a readable form, such as hex or text. FaceNiff is designed as a mobile network sniffer that uses MITM techniques to decrypt SSL traffic and present the captured packets for inspection. It typically achieves this by acting as a proxy and having the device trust its certificate, allowing it to decrypt TLS sessions and display the contents. This capability—capturing HTTPS traffic and decrypting it on the fly for viewing in hex or text—is what differentiates FaceNiff from the other options. Analytic plug-ins are components that extend functionality but aren’t standalone SSL-decrypting sniffers. Capsa Network Analyzer is a general network analyzer that can capture and analyze traffic, including SSL under certain configurations, but it doesn’t inherently perform MITM SSL decryption as a primary feature. Sniffer Wicap is a different type of sniffer with different scope and doesn't specialize in MITM SSL decryption for inspection in the same way FaceNiff does. So, the tool that matches the description of performing SSL decryption via MITM, capturing traffic, and displaying packets in hex or text is FaceNiff.
