On January 27, 2025, DeepSeek, a renowned Chinese AI startup, announced that it was temporarily restricting new user registrations due to a significant cyber attack. According to the company’s status page, the registration process now only supports mainland China mobile phone numbers, likely as a protective measure to limit further vulnerabilities. This incident highlights the growing sophistication of cyber threats in today’s digital landscape.
Powered by the DeepSeek-V3 model, which its creators say “tops the leaderboard among open-source models and rivals the most advanced closed-source models globally,” the artificial intelligence application has surged in popularity among U.S. users since it was released on Jan. 10, according to app data research firm Sensor Tower.
Little is known about the company behind DeepSeek, a small Hangzhou-based startup founded in 2023, when search engine giant Baidu released the first Chinese AI large-language model.

Who’s Responsible?
As of now, no group or individual has claimed responsibility for the attack. However, the breach aligns with patterns commonly seen in large-scale cyber operations, often orchestrated by advanced cybercrime syndicates or state-sponsored actors. These entities frequently target innovative technologies to exploit vulnerabilities for financial gain or espionage.
Techniques Used in Modern Cyber Attacks
While specific methods used in the DeepSeek incident remain unclear, attackers today commonly use:
Phishing and Credential Theft: Deceiving users into revealing sensitive information.
Exploitation of AI Models: Targeting machine learning systems to manipulate data or disrupt services.
Botnet Attacks: Launching distributed denial-of-service (DDoS) attacks to overwhelm systems and cause downtime.
These strategies are designed to infiltrate systems, compromise data, and disrupt services, often with minimal detection.
