Cyber Security Update July 2021

SoftwareONE believes there is a need for additional information when it comes to cybersecurity, as organizations have made it clear that investment in a proper security strategy is paramount. SoftwareONE’s monthly Cyber Security Update provides information on the most recent threats and breaches and how to react to them in order to stay on top of malware and ransomware threats.

Hot Topic of the Month: How to Deal with the Windows PrintNightmare Vulnerability

Lately, security technologists far and wide rushed to perform an out-of-band patch for a Microsoft zero day vulnerability dubbed PrintNightmare (CVE-2021-34527) affecting all versions of Windows. Windows has a vast footprint, accounting for 73% of operating systems on desktop PCs, according to Statista data.

PrintNightmare affects all users on supported versions of Windows, which has the print spooler service enabled by default to allow users to print, either locally or over a network. According to Microsoft, an attacker could exploit PrintNightmare to run arbitrary code with system privileges. This could allow them to install programs, view, change, or delete data and create new accounts with full user rights.

Windows client and server computers that aren't domain controllers can be affected if Point and Print is enabled or the Authenticated Users group is nested within another group in the mitigation section.

What you can do if your organization is affected

We recommend applying the following manual solutions suggested by Microsoft:

Solution 1. Disable the Print Spooler service

If your company can properly disable the printer spooler service, use the following PowerShell command:

Stop-Service -Name Spooler -Force

Set-Service -Name Spooler -StartupType Disabled

Disabling the print spooler service disables local and remote printing features.

Solution 2. Disable Inbound Remote Printing via Group Policy

You can configure the setting to disable inbound remote printing through group policy as follows:

  • Computer Configuration/ Administrative Templates/ Printers
  • Disable the ‘Allow Print Spooler to accept client connections:’ policy to block remote attacks
  • Restart the print spooler service for group policy to take effect

This policy blocks inbound remote printing operations, blocking remote attack vectors. The system no longer functions as a print server. However, local printing to directly connect the device is still available.

Prevent Data Breaches Caused by Insiders

The risk of being attacked by hackers and virtual thieves is nearly everywhere. While protecting your company’s data by securing your network is crucial, many businesses overlook the risks inside the office. Here are ten security risks that your IT teams needs to be aware of.
