Traveling on business, you check into a business-friendly hotel for a few days. You approach the front desk of the hotel, checking in after a long flight. But, the front desk staff is, unfortunately, unable to check you in because the hotel’s electronic key system has been hacked. Someone on the hotel’s staff opened an email from an unknown party, clicked on an unknown link, and malware has infected the electronic key system. So, until ransom is paid, keys cannot be issued. Would you ever stay at that hotel again? Probably not.
