In this blog post we are providing both sourcetype and datamodel SPL searches where possible. This story consists of seven new and two existing detection analytics. The Splunk Threat Research team is releasing a new analytic story named ‘ PrintNightmare CVE-2021-34527’ to help security operations center (SOC) analysts detect successful exploitation scenarios.

Index = win Detections for PrintNightmare To ingest them into Splunk, a similar configuration as below can be used in nf. Print service logs may not be enabled by default. Security teams can leverage these datasets to validate or enhance detection security posture without having to actually replicate the attacks. We are also releasing the attack_data datasets generated using the publicly available exploit against a victim endpoint. WinEventLog:Microsoft-Windows-PrintService/Operational.XmlWinEventLog:Microsoft-Windows-Sysmon/Operational.This analysis was focused on 3 data sources:

These detections were developed in an Attack Range environment where exploitation was reproduced with some of the released POCs. This blog post describes detection opportunities cyber defenders can leverage to identify successful exploitation of CVE-2021-34527 in their environments. We also encourage a defense-in-depth approach to complement the prevention efforts with detection and monitoring controls. Index= sourcetype=WinHostMon source=serviceĭisp_Name,values(StartMode) as Start_mode,values(Started) as Started,values(State) as State by host This can be used to track mitigation progress: Then, perform a search across the WinHostMon data to easily show you what servers have the Print Spooler service enabled or running. Simply enable the WinHostMon input from the Splunk Add-On for Windows to report on the status of services on each server (highlighted below): # Host monitoring # If you want a very quick way of understanding your exposure to this vulnerability, you can do so if you have Universal Forwarders deployed across your server fleet.

The Splunk Threat Research team recommends taking immediate actions to mitigate this vulnerability using the documented workarounds as no official patches have been released yet. Successful exploitation to obtain a reverse meterpreter shell on a Domain Controller

In the most impactful scenario, an attacker would be able to leverage this vulnerability to escalate their privileges in an Active Directory environment from a low privileged domain user to full domain administrator privileges by executing malicious code on a Domain Controller as shown below.
#Lansweeper printnightmare driver#
The vulnerability affects the Print Spooler service, which is enabled by default on Windows systems, and allows adversaries to trick this service into installing a remotely hosted print driver using a low privileged user account.
#Lansweeper printnightmare Patch#
No patch is available at the time of writing.
#Lansweeper printnightmare update#
Update 07/15: Microsoft reported a new privilege escalation vulnerability, CVE-2021-34481, that could allow attackers to execute malicious code as SYSTEM. An attacker can still use the local privilege escalation component to gain SYSTEM level privileges. Update 07/06: Microsoft released an emergency patch to address this vulnerability, but it did not fully resolve the issue as the patch only addresses the Remote Code Execution component. Yesterday, July 1, Microsoft assigned this flaw a new CVE, CVE-2021-34527. On Tuesday, June 29th, a security researcher posted a working proof-of-concept named PrintNightmare that affects virtually all versions of Windows systems. On Monday, June 21st, Microsoft updated a previously reported vulnerability ( CVE-2021-1675) to increase its severity from Low to Critical and its impact to Remote Code Execution.
