Penetration Testing for Hotels and Hospitality Businesses in the UK

Penetration testing for hotels and hospitality businesses in the UK

Hotels and hospitality businesses face a combination of cyber security risks that is almost unique in the UK economy: high-value payment card processing, large volumes of personal data, complex booking and property management systems, and a customer relationship that creates multiple attack surfaces from reservation through to checkout.

Why hospitality businesses are targeted

Payment card data is the primary target. Hotels process significant volumes of card transactions — room bookings, restaurant bills, spa treatments, event payments. Point-of-sale systems and booking engines are consistently targeted by financially motivated attackers seeking card data.

Guest personal data has value beyond card numbers. Guest profiles at larger hotels contain names, addresses, passport details, travel history, loyalty point balances, and preference information — a rich dataset for identity fraud and targeted attacks.

Loyalty programme accounts are frequently targeted by credential stuffing attacks. Accumulated loyalty points have real monetary value and can be transferred or redeemed by attackers who gain access to accounts.

The booking engine is a primary attack surface

Online booking systems — whether proprietary or through third-party platforms — handle payment data and personal information. Vulnerabilities in booking engines have led to significant data breaches at major hotel groups globally.

For smaller independent hotels and groups using custom or semi-custom booking solutions, security testing of the booking engine is particularly important. These systems often receive less security investment than the flagship systems of major chains.

Direct booking websites

Hotels have increasingly invested in direct booking websites to reduce dependence on OTAs. These sites handle payment processing, personal data collection, and in many cases link directly to property management systems. Security vulnerabilities in these sites create direct exposure for the business.

PCI DSS obligations

Hotels that process payment cards are subject to PCI DSS (Payment Card Industry Data Security Standard). PCI DSS requires regular security testing of systems that handle card data, including vulnerability scanning. Non-compliance creates both financial penalties and increased liability in the event of a breach.

Common vulnerabilities in hospitality systems

Booking forms and enquiry forms accepting user input are tested for injection vulnerabilities. Authentication systems for guest portals and loyalty accounts are assessed for brute force protection. Email systems are checked for domain spoofing protection — important given the frequency of phishing targeting hotel guests. API integrations between booking engines and property management systems can expose data if not properly secured.
