China's artificial intelligence (AI) startup DeepSeek said on Tuesday that it had been hit with large-scale malicious cyberattacks, while a Chinese cybersecurity specialist noted that the IP addresses associated with the attacks all show their geographic locations in the United States.
An analysis report from Chinese cybersecurity company QAX restored the entire timeline of the cyberattacks. According to the data, the attacks began on Jan 3 and the number of attacks surged on Monday and Tuesday.
The brute-force attacks have become the primary strategy lately, which differ from the distributed denial-of-service (DDoS) attacks previously used by the attackers, according to Wang Hui, a cybersecurity specialist from QAX.
"They are actually two types of attacks. The DDoS attack primarily consumes the server's resources or occupies its bandwidth, making it impossible for users to access the system. The brute-force attack, on the other hand, targets DeepSeek users' password. The attacker steals the user's password, and once they have it, they can access the user's account and perform actions like asking questions or searching. They can also view the user's activities on DeepSeek and potentially access the user's private information. We can monitor the traffic from these brute-force attacks. Each IP address has a geographic location, and the IP addresses associated with the attacks all show geographic locations in the United States," he said.
Wang added that several Chinese leading companies had been attacked for economic gains or political reasons.
"At least based on the incidents we've observed so far, it seems that major Chinese companies which lead their respective fields, such as the one which produces the Black Myth: Wukong and now DeepSeek, had been targeted for economic gains or political reasons," said the specialist.
In January 2025, DeepSeek released its latest model, DeepSeek-R1, which has attracted significant attention for its advanced reasoning capabilities. The model is said to have achieved performance comparable to leading AI systems, such as OpenAI's ChatGPT, but at a fraction of the development cost.
Chinese AI startup hit by large-scale malicious cyberattacks
Candlelight memorials were held across China on Saturday to honor the victims of the Nanjing Massacre during Japan's aggression against China in 1937.
The Nanjing Massacre took place when Japanese troops captured the then-Chinese capital on Dec. 13, 1937. Over the course of six weeks, they proceeded to kill approximately 300,000 Chinese civilians and unarmed soldiers in one of the most barbaric episodes of WWII.
Saturday marks the 12th National Memorial Day for Nanjing Massacre Victims.
In Nanjing, now the capital of east China's Jiangsu Province, a candlelight memorial and international peace rally was held on Saturday night, joined by around 200 participants from China and across the world.
As night fell over the city, people from different walks of life gathered at the square of the Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders to pay tribute to those killed.
Participants included representatives of inheritors of the historical memory of the Nanjing Massacre, descendants of international friends who aided China during the war, and young students. Dressed in plain attire, they took part in the solemn commemorative event.
Five representatives from various sectors passed along illuminated bouquets of Zijin grass, known as February orchid in Nanjing and radish flower in Japan, jointly forming a light display spelling out the word "Peace." Candles were also arranged into the shape of a dove, symbolizing the shared hope for lasting peace.
"This history is deeply cruel and painful, but we must remember it. Only by remembering history can we truly cherish the peace we enjoy today. When I grow up, I hope to work together with others to safeguard peace," said Yue Cen, a student from Nanjing Foreign Language School's Xianlin Campus.
A similar candlelight memorial was also held in Shenyang, the capital of northeast China's Liaoning province, where the September 18 Incident in 1931 marked the start of Japan's 14-year invasion of China.
More than 200 representatives from various sectors gathered at the 9.18 Historical Museum to pay tribute, lighting candles in memory of the Nanjing Massacre victims.
"On the National Memorial Day, the nation remembers its suffering. It reminds us to cherish the peace that was won at the cost of lives. I will study harder, strengthen my abilities, and contribute my youth to national rejuvenation," said Li Shuhang, a student from Shenyang University.
