By utilizing network monitoring or packet sniffing, an attacker can intercept and view this sensitive information. This could potentially give them access to private data or allow them to compromise the system.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2667704571\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>An attacker might use a tool like Wireshark to monitor network traffic and intercept the unencrypted data.
