[Asia Economy Reporter Kwon Jae-hee] Microsoft (MS) announced on the 7th (local time) that a serious security vulnerability was discovered in its PC operating system (OS) 'Windows' and urged users to update their systems.

According to CNN on the same day, MS identified that the newly discovered security vulnerability affects the latest OS versions, Windows 10 and Windows 7, and recommended users to install the update immediately.

The problematic security vulnerability is a flaw called 'PrintNightmare,' which is known to affect Windows' Print Spooler service. It allows multiple users to access the printer.

The Print Spooler temporarily stores print jobs in the computer's memory when a print command is issued but the printer is turned off or not yet ready to process the job.

Researchers from Sangfor, a Chinese cybersecurity and cloud company, accidentally posted a guide exploiting this vulnerability online and then deleted it. However, it had already spread to other sites such as the developer platform 'GitHub.'

Microsoft explained that if hackers exploit this vulnerability, they can install programs on other users' computers, read and delete data, and even create new user accounts with full privileges.

CNN pointed out, "In this case, hackers gain sufficient control to cause serious damage to other users' PCs."

Windows 10 is installed on 1.3 billion devices worldwide.
