China Presses Tech Firms Over Nvidia H20 AI Chip Purchases Amid Security Concerns

/in /tarafından

Chinese regulators have questioned major domestic tech firms, including Tencent, ByteDance, and Baidu, over their purchases of Nvidia’s H20 AI chips, sources told Reuters. The Cyberspace Administration of China (CAC) and other agencies asked companies to justify why they were opting for U.S. chips instead of domestic alternatives and raised concerns that data submitted to Nvidia for U.S. government review could expose sensitive client information.

While Beijing has not issued a direct ban on Nvidia’s H20, companies were cautioned about its use in government-related or security-sensitive projects. Bloomberg earlier reported that firms received official notices discouraging reliance on the chip, while The Information claimed ByteDance, Alibaba, and Tencent were ordered to halt purchases outright. These reports could not be independently confirmed by Reuters.

Nvidia defended the H20, stressing it is “not a military product or for government infrastructure,” while noting China has never relied on U.S. chips for government operations. The chipmaker designed the H20 specifically for China after U.S. export curbs in late 2023 restricted sales of its most advanced processors. Although Washington briefly banned its sale this year, the Trump administration reversed the decision in July, restoring limited access.

The scrutiny threatens a key revenue source for Nvidia, which made $17 billion from China last fiscal year — about 13% of its global revenue. State media have recently amplified criticism, portraying the H20 as technologically inferior and a security risk. Meanwhile, Chinese chipmakers like Huawei are working to produce domestic AI processors rivaling Nvidia’s offerings, though U.S. sanctions on advanced equipment remain a hurdle for large-scale production.

The tensions underscore Beijing’s push for self-sufficiency in semiconductors as Washington weighs tighter controls. U.S. President Donald Trump has hinted he may allow Nvidia to sell a scaled-down version of its Blackwell AI chip in China, even as concerns grow over the military applications of advanced AI. At the same time, an unusual deal now requires Nvidia and AMD to share 15% of China chip sales revenue with the U.S. government.

US Federal Judiciary Reports Sophisticated Cyberattacks on IT Systems

/in /tarafından

The Administrative Office of the U.S. Courts announced on Thursday that federal judiciary IT systems have been targeted by “recent escalated cyberattacks of a sophisticated and persistent nature.” The disclosure follows a Politico report claiming that the judiciary’s electronic case filing system was compromised in a sweeping hack, potentially exposing sensitive court data across several states.

According to Politico’s sources, the breach affected the federal case management system, including the Case Management/Electronic Case Files (CM/ECF) platform used by legal professionals to upload and manage documents, and the Public Access to Court Electronic Records (PACER) system, which provides public, paid access to certain case data.

While the Administrative Office’s statement did not confirm the full extent of Politico’s findings, it stressed that the judiciary is focusing on enhancing security measures and collaborating with courts to reduce the impact on litigants. The nature of the attacks and the actors behind them have not yet been disclosed.

U.S. Senators Call for Probe into Data Security Risks of Chinese AI Model DeepSeek

/in /tarafından

A group of seven Republican U.S. senators led by Ted Budd urged the Commerce Department on Tuesday to investigate potential data security risks associated with Chinese open-source AI models such as DeepSeek.

The senators—including Jon Husted, Todd Young, John Cornyn, John Curtis, Bill Cassidy, and Marsha Blackburn—requested an assessment of whether applications using DeepSeek collect data that is transmitted back to Chinese servers, and if these AI models are sharing American personal or corporate information with China’s military or military-linked companies.

Their letter also sought information on any improper access by Chinese open-source models to export-controlled semiconductors or breaches of usage terms of U.S. AI models aimed at enhancing Chinese AI capabilities.

Bipartisan legislation has been proposed to ban DeepSeek’s use on federal government devices and networks, as well as prohibit its use by federal contractors in government projects.

Commerce Secretary Howard Lutnick stated in January that DeepSeek appeared to have misappropriated U.S. AI technology and promised to enforce restrictions. The Commerce Department did not immediately respond to requests for comment.

In June, Reuters reported that DeepSeek was assisting China’s military and intelligence services and was attempting to use Southeast Asian shell companies to obtain advanced semiconductors barred from shipment to China under U.S. export rules.

These developments underscore growing skepticism in Washington over DeepSeek’s rapid rise, with officials suggesting the Chinese firm’s AI prowess heavily depends on U.S. technology.

Based in Hangzhou, DeepSeek shocked the tech world in January by claiming its AI reasoning models matched or outperformed leading U.S. models at a fraction of the cost.
