South Korea's electronics maker, LG, is reportedly the last big company to hit the WannaCry ransomware.
The WannaCry first released in May of this year, is a form of ransomware that exploits a Windows vulnerability that has already been patched by Microsoft shortly after its release. Microsoft it space that, it released emergency patches even for Windows XP in an effort to protect users. So those who managed to update their systems avoided the risk. 
But this never happened with LG's systems and apparently one service self-service platform the company operated in South Korea has been infected with WannaCry.
It is currently unknown how many computers were infected on LG's network, so the company decided to disable some of its systems to prevent the ransomware from spreading. LG has announced that it will not pay ransom.
"We analyzed the villain code which caused delays at some customer service centers on August 14 with the help of KISA [Korea Internet & Security Agency] and we confirmed that it was indeed ransomware. According to KISA, yes it was the WannaCry ransomware ", said a company representative.
LG has managed to restore all affected systems in less than 2 days, but it does not seem to have identified how it was infected by ransomware.
On the other hand, what is certain and known is that computers infected by WannaCry were not updated with Microsoft's latest updates.
