This room serves as an excellent bridge between beginner CTFs (like Pickle Rick or Simple CTF ) and advanced challenges (like HackPark or Mr. Robot ). It is also a fantastic primer for the eJPT or OSCP certification labs, where similar multi-step attack chains appear frequently.

HINT: In Wireshark, filter for icmp and look for packets with a length not equal to the standard 98 bytes.
