According to tech giant Microsoft, a group of Chinese hackers were responsible for an attack on their email servers yesterday.
Microsoft’s threat intelligence centre said the attack on Tuesday was carried out by Hafnium, a supposedly state-sponsored entity operating out of China, which tried to steal information from a broad range of United States-based organisations, including law firms and defense contractors.
Hafnium used servers located in the US to launch its attack, in order to operate out of China.
The company declined to say how successful the attack was, but noted that the number was limited.
Microsoft has also briefed the US government agencies regarding the cyber attack.
A spokesperson for China’s Ministry of Foreign Affairs said that the country “firmly opposes and fights all forms of cyber-attacks and thefts in accordance with the law.”
