NEW YORK, Jan 26 (Reuters) – Nike (FROM) says it is investigating a potential data breach, after a group known for cyberattacks claimed to have leaked a trove of data related to its business operations.

“We always take consumer privacy and data security very seriously,” Nike said in a statement. “We are investigating a possible cyber security incident and are actively evaluating the situation.”

Ransomware group World Leaks said on its website that it had released 1.4 terabytes of Nike data. Reuters could not immediately download the data or verify the claim. An attempt to locate contact information for the hackers was not immediately successful.

Nike declined to comment on the details of its investigation or whether any ransom was paid.

Nike, whose business has been struggling, is trying to re-establish itself as the world’s dominant sportswear brand amid losses in market share to smaller rivals. Its shares were flat late Monday morning.

It was not immediately clear whether the breach might have affected data from any of Nike’s major wholesale partners, including Dick’s, Macy’s and JD⁠Sports.

Dick’s and Macy’s did not immediately respond to requests for comment Monday. A JD Sports spokesman had no immediate comment.

Data hackers have wreaked havoc in the corporate world over the past few years and cost companies big bucks. MGM Resorts International, Clorox, and UnitedHealth Group suffered major attacks in 2023 and 2024. The MGM attack cost the company at least $100 million in damages, while Clorox suffered a drop of more than $350 million in quarterly net sales.
