Nike is investigating a potential data breach after the extortion group WorldLeaks claimed to have stolen 1.4TB of internal data. The group published samples on its leak site, showing 188,347 files that appear to relate to design and manufacturing, rather than customer information. File names include categories like "Women's Sportswear" and "Garment Making Process," indicating a focus on product development rather than personal data. Nike has not confirmed the specifics of the breach but maintains that consumer privacy and data security are top priorities. The company has not indicated whether it will pay any ransom. Currently, there's no evidence suggesting that customer or employee records were compromised, which mitigates immediate regulatory concerns. However, the leaked design files and training documents could still have significant implications for Nike's competitive edge. WorldLeaks, reportedly a rebranded version of the Hunters International ransomware gang, is shifting tactics. Instead of encrypting data for ransom, they are stealing files outright and threatening to leak them. This approach reflects a broader trend among cybercriminals, especially as law enforcement pressure mounts and companies become less willing to pay for decryptors. Other victims of WorldLeaks include manufacturers and industrial firms, with Dell previously denying any significant data loss from an attack last year. The incident with Nike arrives shortly after Under Armour disclosed a breach involving the Everest ransomware gang, which exposed detailed information from 72.7 million accounts. The growing targeting of fashion and sportswear companies highlights vulnerabilities in their global supply chains, where the flow of new designs and proprietary information makes them attractive targets for data thieves.
