  • The developments came on Friday the apparent deadline for owners of some infected machines to pay the ransom or lose their files forever

It is considered that numerous infected devices were using XP, though, the latest data shows that most of these devices were actually running Windows 7.

Weeks after WannaCry launched a devastating attack that affected the operations of large companies, government agencies, and institutions across the globe, cyber security company Kaspersky Lab learned that about 98 percent of the computers affected by WannaCry are running various versions of the Windows 7 software. The 64-bit edition is used widely by large organizations, according to figures from Kaspersky.

On May 14, 2017, Microsoft highlighted in a blog the link between WannaCry and an exploit stolen earlier this year.

That put Microsoft's decision to issue a security patch for Windows XP in a different light.

Spanish telecoms firm Telefonica, French carmaker Renault, German rail firm Deutsche Bahn, logistics firm Fedex, Russia's interior ministry and 61 NHS organisations were all caught out by WannaCry. That's especially true of extortion rackets like WannaCry's payload, which encrypts files and then demands a ransom payment to decrypt those hijacked files. So far, a reported 296 payments totalling $99,448 (£76,555) have been made to the bitcoin wallets tied to the ransomware. There have been no reports that anyone who paid has had their data restored by those behind the attack.

The company also argued that even security experts agree that getting the latest computer system is one step to having the best cyber protection. Many systems failed to upgrade from Windows XP, the version of Microsoft's OS that debuted in 2001, and this was considered one of the main reasons they were hit hard by the rasomware.

"There were no real WannaCry infections of Windows XP", said Costin Raiu, director of Kaspersky Lab's global research and analysis team, in an interview Monday. Worst hit - Windows 7 x64.

Rather than take aim at Windows XP, WannaCry targeted Windows 7 and Windows Server 2008, Kaspersky's data showed.

On the other hand, less than one in a thousand were powered by Windows XP making it nearly insignificant for the discussion.

Raiu said that the Windows XP computers that were compromised were likely infected manually for testing purposes.

Many suggested that the reason United Kingdom hospitals suffered was because many of them still relied on programmes that required Windows XP - a version of Microsoft's OS that debuted in 2001.
