Flash Report: Luxshare Allegedly Breached by RansomHouse

Key Findings

• On January 9, 2026, ransomware and digital extortion (R&DE) collective “RansomHouse” announced an alleged breach of Luxshare Precision Industry Co. Ltd. (Luxshare)—one of the largest third-party manufacturers for tech giant companies—on its dark web victim leak site.
• Luxshare is a China-based major electronics manufacturer whose partners include, but are not limited to, Apple, Nvidia, LG, Geely, and Tesla—companies whose data has allegedly been exposed in the RansomHouse breach.
• Although some reports suggested the now-defunct “RansomHub” collective claimed responsibility for the alleged attack, it is almost certain that RansomHouse is the R&DE responsible for the breach; any alleged affiliations or cooperation between the two collectives remain unconfirmed.
• The data allegedly exposed by RansomHouse could very likely be sold to competitors and used for reverse engineering or by criminals seeking to manufacture counterfeit devices and technology.

Details

On January 9, 2026, R&DE collective RansomHouse announced an alleged breach of Luxshare—one of the largest third-party manufacturers for tech giant companies—on its dark web victim leak site. The collective claims the breach took place on December 15, 2025; sample data files allegedly pertaining to Apple Inc. were added to the post for download on January 20, 2026. This was almost certainly done in an effort to garner attention. As of writing, neither Luxshare nor Apple has confirmed the alleged data breach.

• RansomHouse claimed the stolen data pertains to 2019–2025 and includes confidential archives of 3D product models, circuit board designs, and other device architecture drawings and layouts.
• Notably, researchers have found personally identifiable information (PII) in the data sample provided by the collective; the PII appears to include the full names, job positions, and work emails of individuals working on specific projects, as well as other sensitive business operations information.¹

RansomHouse became active in May 2022 and has claimed responsibility for at least 162 separate R&DE incidents since. It is a self-proclaimed “extortion only” and “force for good” ransomware-as-a-service (RaaS) group that aims to shine a light on “lacking companies.”² While some reports suggest that the now-defunct threat collective RansomHub has claimed responsibility for this alleged breach, it is almost certain that RansomHouse is the R&DE collective responsible.^3,4

• Cybersecurity researchers reportedly suspect RansomHouse of being an offshoot of the Babuk ransomware group, with alleged links to Russia and Eastern Europe.⁵
• RansomHub is a seemingly separate, prominent RaaS threat group first observed by ZeroFox in February 2024; since April 1, 2025, the group’s leak site has been offline, and no new victims have been observed.⁶
• ZeroFox notes that both groups are distinct entities, and any alleged affiliations or cooperation between the collectives remain unconfirmed.

As of writing, ZeroFox is unable to ascertain the authenticity of RansomHouse’s claims or the breach itself; however, if legitimate, a major third-party vendor breach would very likely have significant implications for the affected companies, their products, the global supply chain, and cybersecurity. Such supply chain attacks rely on actors targeting third-party vendors to gain illicit access to the primary target—in this case, likely Apple and other large tech companies.

The data allegedly exposed by RansomHouse could very likely be sold to competitors and used for reverse engineering or by criminals seeking to manufacture counterfeit devices and technology. Losses of private customer data, proprietary information, and sensitive internal communications will almost certainly manifest into market disadvantages and supply chain vulnerabilities, which can have long-term effects on both the organization and the broader industry.

Recommendations

• Develop a comprehensive incident response strategy.
• Deploy a holistic patch management process, and ensure all IT assets are patched with the latest software updates as quickly as possible.
• Adopt a Zero-Trust cybersecurity architecture based upon a principle of least privilege.
• Implement network segmentation to separate resources by sensitivity and/or function.
• Ensure critical, proprietary, or sensitive data is always backed up to secure, off-site, or cloud servers at least once per year—and ideally more frequently.
• Implement secure password policies, phishing-resistant multi-factor authentication (MFA), and unique credentials.

• Configure email servers to block emails with malicious indicators, and deploy authentication protocols to prevent spoofed emails.
• Proactively monitor for compromised accounts and credentials being brokered in deep and dark web (DDW) forums.
• Leverage cyber threat intelligence to inform the detection of relevant cyber threats and associated tactics, techniques, and procedures (TTPs).

Scope Note

ZeroFox Intelligence is derived from a variety of sources, including—but not limited to—curated open-source accesses, vetted social media, proprietary data sources, and direct access to threat actors and groups through covert communication channels. Information relied upon to complete any report cannot always be independently verified. As such, ZeroFox applies rigorous analytic standards and tradecraft in accordance with best practices and includes caveat language and source citations to clearly identify the veracity of our Intelligence reporting and substantiate our assessments and recommendations.

ZeroFox Intelligence Probability Scale 

All ZeroFox intelligence products leverage probabilistic assessment language in analytic judgments. Qualitative statements used in these judgments refer to associated probability ranges, which state the likelihood of occurrence of an event or development. Ranges are used to avoid a false impression of accuracy. This scale is a standard that aligns with how readers should interpret such terms.
