It’s Microsoft released an emergency patch to fix a critical bug in Windows Print Spooler that bad actors are actively using, he noted The Verge. A few days ago, the technology giant issued a security warning to inform users of the alleged error PrintNightmare, although he did not name the bad actors who currently use him to infiltrate the victims’ computers.
Attackers exploiting the vulnerability can remotely run system-level privilege code, giving them the ability to install programs on victims’ computers, delete or change data, and create new accounts with full user rights. The vulnerability affects all versions of Windows, and the company has advised users to disable Print Spooler to disable local and remote printing to prevent hackers from entering. They can also disable only the possibility of incoming remote printing via group rules.
After investigating the vulnerability, Microsoft released patches for several versions of Windows Server, Windows 10, Windows 8, and even Windows 7 – security updates for this OS completed in January 2020 – platforms. The vulnerability is classified as “critical”, meaning that its “exploitation could allow code execution without user interaction”. Microsoft asks users to install updates immediately or take steps to protect their systems if they cannot.
