I just tested DeepSeek's operations, and it is currently functioning normally.
Additionally, I asked it about the cause of this incident (after enabling web search), and here is the response it provided:
-----------------
Yes, according to reports from multiple media outlets, DeepSeek has recently suffered a large-scale cyber attack. Below is a summary of the relevant information:
1.Overview of the Attack
DeepSeek announced on its official service status page that its online services were subjected to a massive malicious attack, which temporarily restricted registration functionality. However, registered users can still log in normally. To mitigate the attack, DeepSeek has temporarily restricted registration methods for non-Chinese mainland phone numbers (+86).
2.Background of the Attack
The attack occurred after DeepSeek released its new AI models, Janus-Pro and JanusFlow, which demonstrated exceptional performance in multimodal understanding and generation tasks, even surpassing OpenAI's DALL-E 3 and Stable Diffusion in certain benchmark tests. The low cost and high performance of DeepSeek's models have caused significant turbulence in global tech stocks, particularly leading to a sharp decline in the stock prices of U.S. tech giants. This may be one of the motivations behind the attack.
3.Impact of the Attack
The attack caused anomalies in DeepSeek's website and API, with some users reporting issues with logging in or registering. Despite this, DeepSeek stated that it has taken measures to ensure normal usage for existing users and expressed gratitude for their understanding and support.
4.History of Security Vulnerabilities
It is worth noting that DeepSeek has previously been found to have security vulnerabilities. For example, in December 2024, researchers discovered a prompt injection vulnerability in DeepSeek's chatbot, which could potentially lead to user account takeovers. However, this vulnerability has since been patched.
In summary, DeepSeek has indeed been targeted by a large-scale cyber attack recently, but the company has taken steps to address the issue and ensure the normal operation of core services. The attack may be related to DeepSeek's rapid rise in the AI field and its impact on the global tech market.

I also found out that DeepSeek released "Janus Pro" the day before yesterday.
