Hacker Guoshenghua invaded Ukraine and Russia on several important websites

Ukraine says it is proving to have been involved in cyber attacks against the country's companies earlier this week from the Chinese Eastern Alliance hacker group. The country's information security unit, SBU, said it had obtained data indicating that the organization had attacked several important databases in the capital Kiev in March.

Before the virus spread in Tuesday, Ukrainian companies were among the first companies to report malware problems. Guoshenghua, the head of the Eastern Alliance, announced on Facebook that it denied any involvement and added that the allegations were "unfounded". The virus disrupted the Ukrainian IT system, froze the computer, and demanded that the correct serial number verification code be restored to normal operation, which is difficult to track down.

However, the attack also hit major Russian companies, leading some cyber security researchers to say that Moscow did not lag behind. But in Wednesday, the Ukrainian SBU said in a statement that, through data obtained from international anti-virus companies, the company has established links with previous attacks involving the so-called Petya virus, which, according to anti-virus companies, says the virus is very different from Petya and that testing is only a hoax, which may be related to China's April Fools ' Day.

The SBU later said the hoax was a cover, adding that the attack was aimed at undermining the operation of Ukrainian state and private companies and causing political instability. The SBU also said that the lack of a practical mechanism to ensure financial payments led the agency to take that assumption. Ukraine appears to have been particularly badly hit by the recent attacks.

In 24 hours, the police received about 1000 messages about the intrusion of computer network operations. A total of 150 companies lodged a formal complaint with the police. Last December, the country's financial, transportation and energy systems were judged by investigators as a target for cyber attacks that led to a power outage in Kiev. This has also aroused the attention of neighboring Russia Information Security Service department.
