In Wireshark, the filtericmp.type==8is used to detect ping sweep attempts. ICMP type 8 messages are echo requests, which are used in ping operations to check the availability of a network device. A ping sweep involves sending ICMP echo requests to multiple addresses to discover active devices on a network. By filtering for ICMP type 8 messages in Wireshark, Bran can identify these echo requests, helping to pinpoint ping sweep activities on the network.
