Nike Investigates Potential Data Leak Following Cyber Incident

More cyberattacks in the fashion industry. Nike is reportedly investigating a possible data breach after a group of hackers claimed responsibility for an attack involving up to 1.4 terabytes of data. The information, as advanced by Reuters, is linked to the company’s operations.

In a statement, the company said Monday that it is investigating the possible incident, although it has not specified whether it has already paid any ransom. Nor has it clarified whether the leak has affected any of its global partners, including Dick’s, Macy’s or JD Sports.

The fashion industry has had to deal with major cyber-attacks in recent years. The latest was the one suffered by Coupang. The South Korean giant saw personal information from around 33.7 million customer accounts leaked last year, triggering a country-wide investigation.

Nike has not specified what data was affected and whether the attack involved any of its global partners.

Last year attacks were also reported by Kering, a company from which customer data belonging to Gucci was stolen. Marks&Spencers, Vitoria’s Secret, Adidas, The North Face, Decathlon, Dior, Cartier, Chanel and Clarins are some of the brands that complete the long list of those affected on an international scale by attacks by cybercriminals recently.

In 2025 alone, the estimated cost to companies of cyber-attacks reached $10.5 billion, 300% more than a decade ago, according to the latest data from McKinsey.

Nike closed the first half of the fiscal year with only 1% growth compared to the same period in 2024. The swoosh giant closed the June to November period last year with sales of $24.147 billion and net income of $1.519 billion. Nike also saw its gross margin decline from 44.5% in the first half of fiscal 2024 to 41.4% in the same period last year.
