Earlier, Microsoft responded to the security advisories mentioned in last week’s PrintNightmare Vulnerability releasedEmergency patch update. The vulnerability exists in the Windows Print Spooler service, through which hackers can remotely run code on the victim’s computer with system-level permissions, perform operations such as installing malicious programs, deleting or modifying data, and creating new accounts with full permissions. At present, Microsoft has found that someone is using PrintNightmare, but it did not mention the specific name in the announcement.

It is worth mentioning that PrintNightmare will affect all Windows versions, and Microsoft’s updates cover Windows Server, Windows 10, Windows 8 and even Windows 7 platforms. The risk of this vulnerability is defined as “critical level.” Before fixing it through an update, Microsoft recommends that users turn off Print Spooler or disable inbound remote printing through Group Policy. But if you have a chance, install the patch as soon as possible just in case.
