07:00 AM. The front office manager arrives for the shift, turns on the computer — and sees only one message on screen: *"Your files have been encrypted. If you don't pay within 72 hours, your data will be permanently deleted."*
This is a real scenario that has unfolded in dozens of hotels worldwide. **Ransomware** is the most dangerous cyber threat capable of devastating the hospitality industry both operationally and financially.
Why Is Hotel Operations So Vulnerable?
A hotel consists of dozens of interconnected systems — PMS, POS, door lock systems, IPTV, front desk computers, and accounting software. A failure in any of these triggers a cascade of operational disasters:
How Do Attacks Happen?
The vast majority of ransomware attacks targeting hotel systems enter through these channels:
1. **Phishing emails:** Malicious files disguised as "reservation cancellations," "invoices," or "guest complaints" are sent to employees.
2. **Exposed remote desktop (RDP):** Brute-force attacks against RDP ports left open by IT teams or PMS support vendors.
3. **Guest Wi-Fi lateral movement:** When guest and corporate networks share the same VLAN, malware from a guest device can reach PMS servers directly.
