This rule detects attempts to abuse an IoT device's firmware update page by sending a large POST request containing the word "firmware" (case-insensitive) to TCP port 80 on the home network. This activity is indicative of an attempt to corrupt the device's firmware, potentially leading to denial of service or unauthorized control.
