He pinged it. No response.
It wasn't supposed to be like this. The "Wireshark Lab" was a routine exercise for the new junior analysts. A controlled environment. A safe little network with three virtual machines, a switch, and a firewall. The goal was simple: capture a standard HTTP login, an FTP file transfer, and a DNS query. Basic pattern recognition.
Dr. Aris Thorne, a senior network engineer with tired eyes and a coffee-stained tie, leaned back in his chair. The clock on the wall of Lab 4 read 2:00 AM. For the past six hours, he had been staring at the same screen: Wireshark. wireshark lab
Aris opened a new capture, this time without a filter.

A text conversation materialized in the "Follow UDP Stream" window. It wasn't machine code. It was English. > Is anyone there? > I can see you. He minimized the window. This was a closed lab. No internet access. No Wi-Fi. Just three VMs on a hypervisor. He checked the source IP again: 10.0.0.25. Client-3. The dummy machine.
