Which tool might Maya use to detect applications that utilize unencrypted passwords?

Wireshark is a powerful network protocol analyzer that captures and displays data packets in real-time. When a user is concerned about applications transmitting unencrypted passwords, Wireshark provides the means to inspect individual packets on the network. By analyzing the packet data, Maya can look for plaintext passwords or sessions that are being sent without encryption. This is particularly useful because it allows for detailed examination of various protocols and can help in identifying vulnerabilities associated with the transmission of sensitive information.

NetFlow, while valuable for monitoring network traffic and analyzing bandwidth usage, does not provide packet-level details necessary to identify unsecured password transmissions. Nmap is primarily a network scanning tool used to discover hosts and services on a network, but it does not analyze packet data for insecure transmissions like passwords. Snort is an intrusion detection system that focuses on identifying malicious activities and anomalies but does not operate in the same capacity as Wireshark in terms of inspecting plaintext data within the packets.

Thus, Wireshark stands out as the appropriate tool for detecting applications that utilize unencrypted passwords due to its packet-sniffing capabilities and advanced filtering options.
