South Korea Blocks DeepSeek Amid Security Concerns, Following Global Warnings

/in /tarafından

South Korea’s industry ministry has temporarily blocked employee access to the Chinese artificial intelligence startup DeepSeek due to security concerns, marking the latest move by governments to restrict the use of certain AI services. A ministry official confirmed on Wednesday that the ban was implemented in response to growing apprehension surrounding generative AI technologies.

On Tuesday, the South Korean government issued a notice urging caution among ministries and agencies regarding the use of AI services such as DeepSeek and ChatGPT in work-related tasks. The notice followed earlier actions by state-run entities, with Korea Hydro & Nuclear Power confirming it had blocked access to DeepSeek earlier this month.

The country’s defense ministry also took action, blocking access to DeepSeek on military computers, while the foreign ministry restricted its use on devices connected to external networks, according to Yonhap News Agency. However, the foreign ministry did not provide further details regarding the specific security measures taken.

DeepSeek, which was not immediately available for comment, joins a growing list of companies facing scrutiny over potential security risks. Both Australia and Taiwan have recently banned the AI service from government devices, citing similar security concerns. In January, Italy’s data protection authority ordered DeepSeek to block its chatbot after the company failed to address privacy issues raised by regulators.

In addition to government actions, private companies in South Korea are also taking precautions. Kakao Corp, a major South Korean chat app operator, instructed employees to refrain from using DeepSeek due to security fears, particularly following its partnership with OpenAI. Other South Korean tech giants, including SK Hynix and Naver, have also restricted or limited access to generative AI services, citing concerns about data security and privacy.

The scrutiny of DeepSeek follows the company’s claim that its AI models are on par with or superior to products developed in the U.S., while being significantly cheaper to produce. South Korea’s information privacy watchdog has announced plans to inquire with DeepSeek about its user data management practices, adding another layer of regulatory attention on the Chinese startup.

 

Samsung Faces AI Chip Sales Slowdown Amid U.S. Export Restrictions

/in /tarafından

Samsung Electronics warned on Friday that its AI chip sales will be sluggish in the first quarter due to U.S. export restrictions on China, as well as a shift in demand toward more advanced chips. The company is working to launch an improved version of its high-bandwidth memory (HBM) chips in March to address these challenges.

Samsung’s struggles are compounded by its reliance on Chinese customers, who accounted for about 20% of its HBM sales. The U.S. government’s expanded restrictions on semiconductor exports have put additional pressure on the company, unlike its competitor SK Hynix, which remains Nvidia’s primary supplier of HBM chips for AI applications.

Kim Jae-june, Samsung’s executive vice president of memory, acknowledged that “temporary restrictions” would impact HBM sales but expressed optimism about future improvements. Meanwhile, Nvidia CEO Jensen Huang recently indicated that Samsung needs to “engineer a new design” to meet Nvidia’s standards.

Despite these efforts, Samsung reported a 29% decline in operating profit for Q4, totaling 6.5 trillion won ($4.48 billion). The company also faces headwinds in the mobile market, where competition from Apple and Chinese rivals has eroded profits. Samsung’s decision to use Qualcomm processors for its entire Galaxy S25 lineup, instead of its in-house Exynos chips, represents another setback for its semiconductor division.

While AI-driven demand for memory chips is expected to recover from Q2 onward, Samsung’s long-term performance will depend on its ability to mass-produce advanced 12-layer HBM3E chips for Nvidia.

 

Samsung Q4 Earnings Expected to Be Hit by Nvidia AI Chip Supply Delay

/in /tarafından

Samsung Electronics (005930.KS), the world’s largest memory chip maker, is forecasted to report slowed profit growth in the fourth quarter, as it struggles to meet Nvidia’s (NVDA.O) soaring demand for AI chips. Despite an expected operating profit of 8.2 trillion won ($5.6 billion) in the quarter ending December, up from 2.8 trillion won a year ago, this figure represents a decline from the previous quarter’s 9.18 trillion won.

Analysts have recently revised their earnings forecasts downward, with some projecting Samsung’s operating profit to fall below 8 trillion won. A key issue has been delays in Samsung’s supply of high-end AI chips to Nvidia, which has continued to impact Samsung’s earnings, despite an October apology from the company for its third-quarter performance and an earlier pledge to address the chip shortage.

In November, Samsung reshuffled its chip division leadership, naming its chip division chief co-CEO and granting him direct control over the struggling memory chip business. Meanwhile, Samsung’s shares fell 32% last year, underperforming the broader market’s 10% decline.

Contrastingly, SK Hynix (000660.KS), a major supplier of advanced AI memory chips to Nvidia, is expected to report record earnings for the fourth quarter, benefiting from strong demand for its products.

The broader semiconductor market is facing additional pressure, with weaker demand for traditional chips used in smartphones and PCs, and rising competition from Chinese chipmakers, leading to declining chip prices. DRAM prices, particularly DDR4 chips used in personal computers, have dropped as much as 13% in Q4 and are expected to fall another 15% in the current quarter, according to TrendForce.

The South Korean won’s depreciation in December to its weakest level in 15 years, fueled by political instability and concerns over U.S. tariffs under President-elect Trump, has provided some relief in the form of increased overseas earnings, but this has not been enough to offset weak chip prices.

Samsung is expected to release detailed results later in January, offering a breakdown of its earnings by business segment.
