      While a fugitive in Mexico, Mr. X remotely infiltrates the
      Arctic Nuclear Fusion Research Facility’s (ANFRF) lab subnet
      over the Interwebs. Virtually inside the facility (pivoting
      through a compromised system), he conducts some noisy network
      reconnaissance. Sadly, Mr. X is not yet very stealthy. Unfortunately for Mr. X, the lab’s network is instrumented to
      capture all traffic (with full content). His activities are
      discovered and analyzed by you!


 * Qual è il numero IP di Mr. X  da cui effettua gli scan?
 * Che tipi di scan ha usato?
 * Che porte sono aperte sulla macchina target?
