Hackers have stolen private customer information from some of the world’s most famous fashion labels. According to reports, the attack hit Gucci, Balenciaga, and Alexander McQueen. All three brands belong to the French luxury group Kering.
The company confirmed that it suffered a data breach earlier this year. In a statement, it explained that an “unauthorised third party” gained access to its systems in June. While Kering did not officially name which brands were affected, the hackers themselves told the BBC that data from Gucci, Balenciaga, and McQueen had been taken.
This attack adds to a growing number of data breaches targeting the luxury fashion industry. Hackers appear to be focusing more on high-end companies that hold valuable customer records.
What Information Was Stolen
The stolen data reportedly contains sensitive customer details. According to the hackers, the information includes full names, phone numbers, email addresses, postal addresses, and even how much each customer has spent in stores.
The group claiming responsibility for the attack calls itself “Shiny Hunters.” They claim they now hold details linked to 7.4 million unique email addresses. Such a large number points to millions of affected customers worldwide.

While the attack sounds alarming, Kering confirmed that no banking or payment card details were accessed. That means credit card numbers and bank account information were not stolen. Even so, personal data such as names, addresses, and contact numbers can still be used by cybercriminals in other harmful ways, such as scams or targeted phishing emails.
The hackers reportedly gave the BBC some of the stolen information as proof. The release of spending records, including how much certain clients purchased, adds another layer of concern, as it exposes private lifestyle habits of wealthy buyers.
Luxury Industry Under Pressure
This breach is not the first to hit luxury brands this year. Other well-known fashion groups have also faced cyberattacks. Earlier in 2025, Richemont’s Cartier was targeted, and several labels owned by luxury giant LVMH were also affected.
In July, authorities in Hong Kong announced an investigation into a leak of about 419,000 customer records at LVMH’s Louis Vuitton. That incident, like the Kering case, showed how cybercriminals are increasingly turning their attention to luxury fashion houses.
Kering explained that it informed regulators and customers about the incident as required by local laws. The company has not shared which countries were most affected, and it declined to comment further when asked by reporters.

The wave of cyberattacks suggests that hackers see high-end retailers as attractive targets. Luxury brands manage not only global sales records but also exclusive client data, making their databases especially valuable.
For now, millions of customers of Gucci, Balenciaga, and Alexander McQueen have learned that their private details may be circulating in the hands of hackers. The incident shows that even the most prestigious fashion names are not safe from the growing threat of cybercrime.
