“In just a few hours, the ransomware targeted over 45,000 computers in 74 countries, including United States, Russia, Germany, Turkey, Italy, Philippines and Vietnam, and that the number was still growing,” Kaspersky Lab, a Russian-based cybersecurity company, said on Friday.

The attack by the ransomware, dubbed WannaCry, is spread by taking advantage of a Windows vulnerability that Microsoft (MSFT, Tech30) released a security patch for in March.

The ransomware code is named WanaCrypt and has been in use by criminals since at least February. However, a new variant dubbed WannaCry was created that makes use of a vulnerability in the Windows operating system that was patched by Microsoft on March 14. Computers that have not installed the patch are potentially vulnerable to the malicious code, according to a Kaspersky Lab blog post on Friday.

Once infected, WannaCry makes users’ computers useless unless a payment is made to those who hacked their system. It locks files on the computers and requires victims to pay $300 per computer, that is to be paid in Bitcoin, an untraceable digital currency, in order to regain control of them.

Infected computers showed a screen giving the user 3 days to pay the ransom. After that, the price would be doubled. And after seven days, the files would be deleted, it threatened.
