How To Fix WannaCrypt Ransomware Backdoor on Windows 7, XP, 8


On Friday, as many as 74 countries have been hit by a huge, fast-moving and global ransomware attack, infecting more than a dozen hospitals in the UK, businesses including FedEx, universities, Spain’s largest telecom company, and more organizations. So far, in past 24 hours, this ransomware has infected nearly 114,000 computers worldwide.

“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.

Cybersecurity firm Avast said it had identified more than 75,000 ransomware attacks in 99 countries, making it one of the broadest and most damaging cyberattacks in history.
