North Korean government regime (North Korea) led by Kim Jong Un began to be hit by the issue as in cyber attacks in 150 countries.
Although not enough for a conclusion, the existing evidence points to Pyongyang's involvement, Deutsche Welle
South Korean cyber security experts (South Korea) claimed to have evidence that North Korea is behind the "Ransomware WannaCry" attacks around the world.
The attack took host computer users and demanded a ransom in the form of Bitcoin.
Simon Choi, Director of Hauri Inc. who produces antivirus software, said Pyongyang is not a newcomer to Bitcoin.
According to him, neighboring north has been actively mining the cyber currency by using a malicious program since 2013.
Last year Choi accidentally conversed with North Korean hackers who claimed to be developing Ransomware. He then immediately contacted the South Korean authorities.
Testimonial Choi is not the first to link North Korea with the "WannaCry" attack.
Earlier researchers at the cyber laboratory owned by Symantec and Kaspersky also found a number of similarities between WannaCry devices with cyber attacks in the past which allegedly done by North Korea.
However, once they caution that the evidence is insufficient to make any conclusions about the mastermind behind the attack.
Kaspersky for example claims it took several weeks to months to gather strong evidence.
WannaCry software attacks millions of computers in 150 countries, including 200,000 public organizations and institutions.
Hackers are rumored to be using Windows security holes once used by the US secret service, the NSA, to spy on Americans.
However, then a hacker leaked the security gap to the public.
Viruses are everywhere!
