In the wake of the Under Armour data breach, the rebranded Hunters International ransomware group, now known as WorldLeaks, has asserted that it has successfully targeted Nike, Inc., a prominent U.S.-based athletic footwear and apparel company. This development is being closely monitored by cybersecurity professionals and business owners alike.
WorldLeaks made its claims public via its official dark web leak site on January 22, 2026. Over the subsequent weekend, the group supplemented its original post with what it describes as corroborative evidence, alleging that over 1.4 terabytes of Nike’s data have been compromised, comprising a total of 188,347 files that are now being disseminated online.
It is significant to note that WorldLeaks was implicated in the Dell data breach in July 2025, wherein the group exfiltrated 1.3 terabytes of sensitive data and subsequently made it public. This calls into question the effectiveness of existing cybersecurity measures, particularly in high-profile targets like Nike.
The Leaked Data
An initial examination of the leaked files indicates a strong emphasis on Nike’s product development, manufacturing, and factory operations. The contents appear to include extensive documentation such as tech packs, schematics, bills of materials, and various training resources. This suggests that the data encompasses detailed design specifications for apparel and sportswear spanning multiple seasons, including materials for upcoming collections.
Additionally, there are frequent mentions of collaborations with factory partners, onsite training sessions, and internal operational metrics. Such documents likely outline the intricate processes involved in how Nike organizes its product testing, cost assessments, and production before the items hit retail shelves. The potential ramifications of this information becoming public could significantly impact Nike’s competitive advantage.
The leaked data further includes internal presentations, strategic plans, and materials related to specific product lines, athletes, and regional markets. Noteworthy references include files on Jordan brand products, women’s performance clothing, and various sports gear, as well as associated artwork and design layouts. These documents may reveal innovations and marketing strategies still in development stages.
Although the leaked files do not appear to contain consumer payment information, their content offers a rare, intrusive look into Nike’s internal operations, supplier relations, and unannounced product ideas—data that would typically remain confidential.
Nike’s Response
Nike has issued a prompt response, indicating that it is investigating the claims brought forward by WorldLeaks. The company emphasized its commitment to consumer privacy and data security, underscoring that it is actively assessing the situation for any cybersecurity incidents.
As the situation unfolds, it remains critical for businesses, especially in the retail and sportswear sectors, to bolster their cybersecurity measures. Hackread.com is actively monitoring developments in this breach and will provide updates as more information emerges.
