3How many customers were affected?
Quest has not disclosed the number of impacted customers. The company, operating for over 30 years, hasn't clarified how far back the exposed records go. With more than 120 properties across Australia, New Zealand, and Fiji, and listings on platforms like Expedia and Booking.com, international guests may also be at risk from this breach.
4Third-party security risks
The identity of the third-party provider responsible for the vulnerability remains undisclosed, along with details about how the breach occurred.

Security professionals emphasize the need for rigorous third-party access controls and regular penetration testing throughout the supply chain.
5Company's response measures
Quest claims to have contacted all affected guests, contained the breach, and completed remediation efforts. The company has initiated forensic investigations and engaged external cybersecurity consultants. However, questions regarding the full scope of lost data remain unanswered, raising concerns about transparency in breach disclosures.
6Similar cases in the industry
The hospitality sector has seen several major data breaches in recent years. In 2023, a global hotel chain reported theft of 10 million guests' credit card details. A booking platform disclosed a leak affecting 20 million users in 2024. These incidents demonstrate persistent security challenges in an industry handling vast amounts of sensitive traveler data.
7Risks for affected customers
Cybersecurity advisors recommend that impacted individuals remain vigilant against phishing attempts. Monitoring financial accounts, checking credit reports, and being cautious with unsolicited communications are crucial protective measures. Some jurisdictions offer free credit freezing services to breach victims as a safeguard against identity theft.
8The importance of data protection
The Quest incident underscores organizations' accountability for customer data security. Regulations like GDPR mandate prompt breach notifications and impose heavy penalties for non-compliance. This case highlights the need for increased cybersecurity investments, employee training, and consumer awareness about personal data sharing practices in the digital age.
