US, UK, and Australia Target Russia-Based Zservers Over Lockbit Ransomware Attacks

/in /tarafından

The United States, joined by the United Kingdom and Australia, has taken coordinated action against Zservers, a Russia-based service provider linked to supporting the notorious Lockbit ransomware attacks. The U.S. Department of Treasury announced the sanctions on Tuesday, highlighting national security concerns related to ransomware operations.

Designations and Actions:

The U.S. Treasury’s Office of Foreign Assets Control (OFAC) added two Russian nationals to its sanctions list, accusing them of being key administrators for Zservers, a company that provides bulletproof hosting services (BPH) commonly used by cybercriminals. These services enable cyber actors, including ransomware groups, to carry out attacks on critical infrastructure both in the U.S. and internationally.

Bradley Smith, acting Under Secretary of the Treasury for Terrorism and Financial Intelligence, emphasized that third-party providers like Zservers play a crucial role in facilitating the operations of cybercriminals, including those behind Lockbit attacks.

Broader Context:

This move is part of a broader effort to combat cybercrime, following similar actions last year that saw joint sanctions from the U.S., UK, and Australia against the Evil Corp ransomware group. The sanctions are aimed at disrupting the infrastructure that supports cybercriminal activities globally.

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.

 

Australia Bans DeepSeek on Government Devices Over Security Risks

Australia has announced a ban on the Chinese artificial intelligence startup DeepSeek from all government devices, citing national security concerns. The government issued a mandatory directive requiring all federal agencies to prevent the use or installation of DeepSeek’s products, applications, and web services on government systems. Any existing instances of these services must also be removed, according to a statement released by the Department of Home Affairs.

Home Affairs Minister Tony Burke described DeepSeek as posing an “unacceptable risk” to government technology, with the ban being enforced to protect the nation’s security and interests. The move was made swiftly, responding to growing concerns regarding the startup’s potential vulnerabilities.

This ban does not apply to private citizens, only targeting government-operated systems. The decision follows a broader international trend, with several other countries, including Italy and Taiwan, also taking steps to restrict DeepSeek’s influence. Taiwan recently banned government departments from using the company’s services, while Italy imposed similar measures.

The launch of DeepSeek has raised alarms in the tech industry, particularly with its low cost and minimal hardware requirements compared to rival AI models. The startup’s emergence has led to significant market volatility, with global tech stocks experiencing declines as investors question the viability of Western investments in AI infrastructure.

Australia’s action is part of its broader efforts to tighten control over foreign technology, following its previous ban of the Chinese social media app TikTok on government devices two years ago over similar security concerns.
