Holiday Travel Scams Reveal Changing Face of Cybercrime

As the summer holiday season approaches and millions of UK consumers prepare to travel, cyber security firm Net-Defence is warning that cyber criminals are entering a new era of trust-based attacks that blur the line between legitimate communication and fraud.

Rather than relying on obvious scams or poorly constructed phishing attempts, attackers are increasingly exploiting real customer data, trusted global brands, and authentic communication channels to make their deception harder to detect.

The warning follows the recent Booking.com security incident, which has underscored how access to genuine customer information can be weaponised in highly convincing phishing campaigns. In April 2026, Booking.com confirmed that unauthorised parties accessed customer reservation data, including names, email addresses, telephone numbers, and travel booking details. While the company has stated there is no evidence that payment card information was compromised, the cyber security firm note that even non-financial data can significantly increase the credibility and success rate of targeted attacks.

Net-Defence is urging organisations to strengthen supply chain resilience and reassess phishing defences in light of these increasingly sophisticated, data-driven threats, Debra Cairns, Managing Director of Net-Defence, said, “What makes this incident particularly concerning isn’t simply that customer information was accessed, it’s how that information can be weaponised. When criminals know your destination, your hotel and your travel dates, they can create scams that feel entirely legitimate.

Cybercriminals are increasingly exploiting trust rather than technology. They’re using genuine customer data, recognised brands and legitimate communication channels to bypass traditional security awareness. That represents a significant evolution in the threat landscape and changes how organisations need to think about cyber resilience.”

Unlike many historic breaches, where stolen information is stored or sold on criminal marketplaces, this incident demonstrates a growing trend towards using genuine, real-time information to make scams appear authentic. Attackers can reference legitimate hotels, booking reference numbers and travel dates, allowing fraudulent payment requests and phishing messages to appear entirely genuine. In some reported cases, scam messages were even delivered through legitimate Booking.com messaging channels, making them significantly harder for customers to identify as malicious.

In recent years phishing attacks relied on volume, with cybercriminals sending thousands of generic emails in the hope that a small percentage of recipients would click malicious links or disclose sensitive information. Increasingly, however, attackers are using genuine information to launch highly targeted spear phishing campaigns. When criminals possess legitimate booking details, they no longer need to guess, they know who is travelling, where they are staying and when they are due to arrive, allowing them to time communications perfectly and create convincing scenarios involving payment verification, booking amendments or reservation cancellations.

Debra adds: “Even security-conscious individuals can struggle to identify these attacks because the information contained within the messages is genuine.”

Although investigations remain ongoing, industry reporting suggests the compromise may have originated through hotel or accommodation partner accounts connected to the wider Booking.com ecosystem rather than the company’s core infrastructure. If confirmed, this would represent another example of a supply chain compromise, where attackers exploit trusted third parties instead of attacking the primary organisation directly.

For Net-Defence, the incident demonstrates a challenge facing organisations across every sector. Modern businesses rely on cloud providers, software vendors, outsourced IT providers, payment processors and numerous third-party suppliers to operate efficiently. Every organisation with access to business systems or sensitive information effectively becomes part of the wider security perimeter.

Debra adds, “Many organisations invest heavily in protecting their own infrastructure but spend considerably less time understanding the risks introduced by suppliers and service providers.”

The timing of the latest incident is particularly significant as millions of people travel during the peak summer holiday season. Fraudsters can exploit genuine reservation details to send realistic messages requesting payment confirmation, warning of booking problems or directing customers to fraudulent payment portals. These attacks combine genuine information with urgency and trust, making them significantly more successful than traditional phishing emails. Beyond financial fraud, travel information can also reveal when someone is away from home, raising wider concerns around privacy and personal security.

Debra added: “People don’t stop being cyber targets when they leave work. Employees travelling for business or booking personal holidays remain attractive targets. If a personal device, business email account or corporate credentials become compromised, the consequences can quickly extend back into the workplace. Security awareness needs to extend beyond office walls.”

Net-Defence believes the Booking.com incident should encourage organisations to review their wider cyber resilience strategy. Alongside robust technical controls, organisations should understand third-party risk, strengthen supplier assurance, enforce multi-factor authentication, provide ongoing security awareness training, monitor for unusual activity and regularly test incident response plans. As businesses become increasingly interconnected, cyber resilience depends not only on securing internal systems but also on understanding the risks introduced by suppliers, cloud platforms and other trusted partners.

Debra states, “Cyber resilience is no longer simply about protecting your own network, organisations need visibility across their entire digital supply chain. Businesses that regularly assess supplier risk, continuously monitor their environments, educate their people and prepare for incidents before they happen will be significantly better positioned as cyber threats continue to evolve. The organisations that thrive will be those that recognise trust has become one of the most valuable and most targeted assets they possess.”
