Kering cyberattack compromises customer data for Gucci Balenciaga and Alexander McQueen brands

Millions of customers of luxury fashion giant Kering—parent company of Gucci, Balenciaga and Alexander McQueen—have had their personal data stolen in a significant cyber-attack. The incident, attributed to the notorious hacking group Shiny Hunters, was confirmed by Kering after unauthorised access to its systems in June 2025.

The breach exposed sensitive information such as customer names, phone numbers and email addresses, raising concerns for clients of some of the most prestigious names in global fashion. Kering has assured the public that no financial information, including bank details or credit card numbers, was compromised. Government-issued identification was also reportedly not affected by the breach.

Kering indicated the affected fashion houses responded promptly, disclosing the breach to authorities and notifying customers in line with local regulations. The French-based company highlighted actions taken to secure affected systems and bolster cybersecurity following the incident, though it did not specify which individual brands were targeted.

Reports from data monitoring sites, as well as samples circulated on Telegram by the perpetrators, suggest that details shared include not only names and email addresses but also dates of birth, with some documentation of luxury purchases up to $86000. Such revelations underscore the lucrative value of data linked to luxury retail clientele.

The attack on Kering follows a recent pattern of high-profile cyber incidents affecting the retail and luxury sectors, including Louis Vuitton and several major British companies. Production disruptions have been observed in industries ranging from retail to automotive, signalling an elevated risk to consumer data and business continuity for prominent European brands.

Kering’s swift disclosure and emphasis on transparent communication seek to restore confidence amongst customers and stakeholders in a challenging cybersecurity climate. As digital threats intensify, the fashion industry faces mounting pressure to safeguard the privacy and security of its global customer base.
