Cyber espionage actors routinely stealing data
US Federal Bureau of Investigation (FBI) has warned companies and government agencies in the country about an attack launched by Chinese government backed hackers.
The "flash" warning issued by FBI has asked businesses to contact FBI if they believe that their companies have fallen victim to the attack.
The FBI said "a group of Chinese government affiliated cyber actors who routinely steal high-value information from U.S. commercial and government networks through cyber espionage."
Previously, the US government publically asked the Chinese government to stop the widespread cyber theft of US corporate data, but Beijing denied carrying out any such activities.
FBI spokesman Josh Campbell said: "The FBI has recently observed online intrusions that we attribute to Chinese government affiliated actors. Private sector security firms have also identified similar intrusions and have released defensive information related to those intrusions."
An official Chinese embassy spokesman denied knowledge of any investigation. "Judging from past experience, conclusions of this kind of investigations are usually lacking in provable facts and hard evidence," he said
