Wireshark dns analysis6/18/2023 ![]() ![]() The areas covered by this room include: NMAP scans (TCP connect scans, SYN scans, and UDP scans) ARP Poisoning/Spoofing (aka Man In The Middle Attacks) detecting hosts via Kerberos, Netbios, and DHCP identifying tunneled traffic in DNS and ICMP communication analyzing FTP traffic analyzing HTTP and HTTPS traffic including detecting Log4j and suspicious user agents and how to decode HTTPS traffic. Wireshark is a free and open-source packet analyzer that allows you to examine network data transmissions in real-time. Domain Name System (DNS) DNS is the system used to resolve store information about domain names including IP addresses, mail servers, and other information. Be sure to follow along below and subscribe to the CyberInsight YouTube Channel to stay up to date on new lab walkthroughs! We shall be following the below steps: In the menu bar, Capture Interfaces. After we start Wireshark, we can analyze DNS queries easily. The DNS statistics window enlists a total count of DNS messages, which are divided into groups by request types (opcodes), response code (rcode), query type, and others. The dump file had Internet control message protocol (ICMP), service message block (SMB), and. DNS returns different codes, request-response and counters for various aggregations. Since this room covers a lot of in-depth topics, I broke down the tasks into three separate lab walkthrough videos. The default port for DNS traffic in Wireshark is 53, and the protocol is UDP ( User Datagram Protocol ). Our first task is to find the protocol that contains time information. ![]() ![]() This is great information if you’re interested in working in a SOC, on a Blue Team, or even supporting IT operations and need to improve your troubleshooting skills. Today we’re talking about one of TryHackMe’s latest room, Wireshark: Traffic Analysis! This room looks at the techniques and key points of traffic analysis with Wireshark and how to detect suspicious activities. ![]()
