Among other things, the FBI points out: Guests generally have minimal visibility into both the physical location of wireless access points within the hotel and the age of networking equipment. Old, outdated equipment is significantly more likely to possess vulnerabilities that criminal actors can exploit. Even if a hotel is using modern equipment, the guest has no way of knowing how frequently the hotel is updating the firmware of that equipment or whether the hotel has changed the equipment’s default passwords. The hotel guest must take each of these factors into consideration when choosing whether to telework on a hotel network.
