DeepSeek suffers major cyber attacks, banning international users

In China, the tech startup DeepSeek faced significant disruption due to cyber attacks on January 27, 2025. These 'large-scale malicious attacks' had a direct impact on the app's service, particularly affecting new user registrations. The incidents blurred the lines of normal operations as only registered users were allowed to log in. DeepSeek, which was founded in 2023, had quickly gained traction in the AI industry after releasing a model touted to rival advanced AI systems developed in the United States. This rapid ascent of DeepSeek came amid increasing China-U.S. tensions related to technological advancements in AI. The agitated response to these cyber attacks highlights the growing concerns in the tech sector over security vulnerabilities and international competition. Following the announcement of disruptions, DeepSeek restricted signup options to phone numbers within China, effectively preventing international users from joining the platform. This strategic move suggests the company is attempting to mitigate any additional risks associated with cyber threats, particularly from external actors who may be looking to undermine its newfound popularity. DeepSeek's AI-powered chatbot, which gained immense popularity on both Apple and Google app stores earlier in the year, quickly hit the No. 1 spot for free applications. The rapid acquisition of users sparked debates about competition between tech giants in the U.S. and emerging players in China. Such growth has raised alarms among U.S. industry observers, especially given reports that DeepSeek's advancements could mean the startup has managed to catch up with established American companies in the field. The ongoing situation remains of high interest as it intertwines with broader narratives surrounding security and competitive technology development between the U.S. and China. The fallout of these cyber attacks could have lasting implications for DeepSeek as it navigates potential reputational damage and the need to reassure users about their data protection. The changes in user registration policy are a clear indication that DeepSeek is prioritizing security while also addressing the needs of its current user base. As these dynamics unfold, it will be crucial for stakeholders to monitor how DeepSeek adjusts its operations in the aftermath of these attacks and how the competition landscape evolves in the realm of artificial intelligence.
