WorldLeaks claims massive Nike data leak
An alleged Nike breach highlights the shift from ransomware encryption to pure data extortion strategies.
Nike has launched an internal investigation following claims by the WorldLeaks cybercrime group that company data was stolen from its systems.
The sportswear giant said it is assessing a potential cybersecurity incident after the group listed Nike on its Tor leak site and published a large volume of files allegedly taken during the intrusion.
WorldLeaks claims to have released approximately 1.4 terabytes of data, comprising more than 188,000 files. The group is known for data theft and extortion tactics, pressuring organisations to pay by threatening public disclosure instead of encrypting systems with ransomware.
The cybercrime operation emerged in 2025 after rebranding from Hunters International, a ransomware gang active since 2023. Increased law enforcement pressure reportedly led the group to abandon encryption-based attacks and focus exclusively on stealing sensitive corporate data.
An incident that adds to growing concerns across the retail and apparel sector, following a recent breach affecting Under Armour that exposed tens of millions of customer records.
Nike has stated that consumer privacy and data protection remain priorities while the investigation continues.
