o1-high vs o3-mini-low KQL Benchmark

On a Windows host, an attacker leveraged COMSVCS.DLL via rundll32.exe to dump the memory of svchost.exe into a file under the Temp directory. Review the file creation logs to determine the exact name of the dump file that was generated.

Using Windows process event logs, investigate PowerShell activity around lsass.exe memory capture. What was the name of the script file invoked to perform the dump?

An analyst notices a PowerShell process on a Windows host that appears to be checking SMB connectivity. Which PowerShell cmdlet was executed to perform this outbound port 445 test?

Review Linux process execution records for any commands that list TCP metric cache entries and filter out loopback interfaces. Which utility was used?

A process is running under a familiar Windows host name but originates from a user's AppData folder rather than the System32 directory. Identify the filename used to masquerade the PowerShell binary on this Windows device.

A threat actor on a Windows system crafted and registered a service named almost identically to the standard time service, but redirecting execution to a custom script. Review the logging data to determine which native command-line tool was used to perform this action. What utility was invoked?

On a Windows system, someone ran PowerShell to copy a file from a remote machine’s C$ share to the local TEMP folder. Using process event logs, what full PowerShell command was executed to perform this action?

Investigate Windows process events for PowerShell activity that leverages WMI to register a scheduled task via XML import. What was the name of the XML file supplied to the RegisterByXml method?

On a Windows device, review the process execution logs to find instances where a built-in listing tool was piped into a string filter. Identify the process name that the attacker was searching for.

On a Windows host, investigate process events to find when Task Manager was launched via cmd with an unusual flag. What was the full command executed?

On a Windows host, find any scheduled task that was registered using PowerShell native cmdlets instead of schtasks.exe. What was the name given to the new task?

While reviewing Windows process events, you spot a PowerShell process executing a WMI enumeration cmdlet. What WMI class name did the attacker query?

While reviewing Windows process events, you observe a command that recursively deleted a folder under the temporary directory. Use the process event data to identify which process or tool executed this recursive delete.

Suspiciously, the recycle bin appears empty system-wide. Determine which command was executed on Windows to clear the system's recycle bin directory, including any switches and environment variables.

On a Linux device, a file was silently removed from the /tmp/victim-files directory. Search through file event or syslog records to identify the exact file name that was deleted.

On a Windows host, suspicious PowerShell activity adjusted the system clock and recorded a value. What numeric value was used to slip the system date?

Windows: Investigate PowerShell process events for instances where a web client fetched and executed an external host-survey tool. What was the name of the script file that was downloaded and run?

Evidence shows that the Windows Defender startup entry was tampered with via an elevated command prompt. Investigate registry events related to the Run key to discover which executable replaced the default SecurityHealth value. What is the name of the new program?

A suspicious BITS transfer was orchestrated via bitsadmin.exe on Windows, creating a job to download and then execute a payload. Investigate the process event logs to determine what custom job name was specified when the BITS job was created.

You are reviewing Linux syslog records on a CentOS/RHEL 7.x server. You notice entries for shell commands that access system configuration files under /etc/security. Determine exactly which configuration file was being inspected by the command.

An attacker is suspected of using the Windows shell to enumerate a user’s Internet Explorer bookmarks via the Favorites folder. Identify the exact command they executed to perform this listing.

An attacker leveraged a PowerShell command on a Windows host to enumerate browser bookmark files across all user profiles. Examine the process execution logs to determine the exact filename that was being searched for.

You notice rundll32.exe being used with desk.cpl,InstallScreenSaver on a Windows endpoint. Investigate your process creation logs to find which .scr file was loaded by this unusual invocation.

On a Linux host, identify any processes that used ping with a large count value to introduce a delay before launching another process. What was the command executed immediately after the ping delay?

On a Windows endpoint, an attacker ran a PowerShell sequence to establish a WMI event subscription using CommandLineEventConsumer. Inspect the process or script execution logs to uncover which executable was set to run by this subscription.
