How many packets did you capture (total of all protocols, not just HTTP)? Now, use display filters to determine how many packets contain your IP address (hint: Use ip.addr instead of the clumsy ip.src or ip.dst format we learned in Step 8). (5 Points).

Texts: Basic attack analysis: 1. Look at captures no. 20 and 22. (You can use the "Go" link at the top of the Wireshark screen to quickly go to a specific capture.) Both packets are ICMP traffic, but there are subtle differences between them. Compare the time-to-live and data field sizes in the two packets. What differences do you see? 2. Do a little Internet research to discover which operating systems use the specific values in their ping commands. What operating system generated the echo request in capture 20? 3. Review packet no. 37 and beyond. What do you think is taking place here? 4. Look at capture 22846. What is suspicious about the flag settings in this packet? 5. What is the IP address of the host being targeted?
An analyst is reviewing the following output as part of an incident: ICMP ECHO REQUEST 192.168.1.10 -> 10.20.30.40 Length=10 ABCDEFGHIJ ICMP ECHO REQUEST 192.168.1.10 -> 10.20.30.40 Length=15 ABCDEFGHIJ ICMP ECHO REQUEST 192.168.1.10 -> 10.20.30.40 Length=20 ABCDEFGHIJ1234567890 Which of the following is MOST likely happening? - The hosts are part of a reflective denial-of-service attack. - Information is leaking from the memory of host 10.20.30.40. - Sensitive data is being exfiltrated by host 192.168.1.10. - Host 192.168.1.10 is performing firewall port knocking.
