A week after the WannaCry attack, analysis of data collected shows that the systems most affected by the malware were Windows 7 and not Windows XP, according to security firm Kaspersky.
Specifically, over 60% + 31% of computers hit by WannaCry were running 64-bit or 32-bit versions (respectively) of the Windows 7 operating system.
Ironically, Windows 7 should have been safe against WannaCry, as Microsoft had been releasing security patches since March 2017. We also shouldn't forget that the operating system is still supposed to be supported.
On the other hand, seeing Windows 7 as the operating system most affected by the WannaCry malware seems to make sense. Because if you consider that it is the leading PC operating system in the world with a market share reaching almost 50%, it seems to be percentage-wise correct.
This means that almost 1 in 2 desktop systems run Windows 7.
It is worth mentioning that Windows 7 is being released in pirated copies on many systems out there, especially in countries like China and Russia, which still use copies of the operating system that are not genuine.
This results in those who use them not being able to update every month, while many users have completely blocked updates to avoid checking for genuine product keys.
Remember that Windows 7 will continue to be supported until January 2020, so genuine systems with this operating system will still receive updates for almost another 3 years.
