o1-low vs o3-mini-high 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 suspects a user or script ran a service enumeration command on a Linux system. Review process events to find the service-listing invocation and specify the full command that was executed.

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?

On a Windows endpoint, look for evidence of a base64-encoded PowerShell payload execution. Which executable launched the encoded command?

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?

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.

Windows process creation logs show a PowerShell-driven file transfer to an FTP service. Which executable was leveraged to perform this exfiltration?

On a Windows device, PowerShell was used to collect a snapshot of running processes. Identify the exact cmdlet that was executed.

Examine the logs from the Linux system for events related to the systemd timer activation. Identify any records indicating that a new timer unit was started and enabled, and determine which timer name was used.

An analyst suspects that a restricted shell escape was executed using a common Perl package manager on Linux. Review the process execution records to determine which tool was invoked to spawn the shell.

Review recent Windows process event logs for PowerShell activity that suggests local group enumeration through WMI. What exact command was executed?

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 Windows system, an attacker used the command prompt to remove one or more default administrative shares. Which share names were deleted?

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?

On a Windows device, there’s evidence that PowerShell history was wiped by deleting the history file. What was the exact command used to perform this action?

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?

Review registry event logs on the Windows host for PowerShell-driven writes to system policy and file system keys. Which registry value names were created during this BlackByte preparation simulation?

A user‐space process on a Linux device invoked a shell to capture and display the system’s environment variables and path. Which exact command was used to perform this discovery?

A Linux host was used to collect various system release files and kernel details, writing them into a single file under /tmp. What was the name of that output file?

A Windows host logs show PowerShell fetching and executing a remote script to gain SeDebugPrivilege token duplication. Which Empire module was invoked?

A Windows host recorded a process that simply executes the system’s native time utility. Without spelling out the query, determine which command was run based on process creation events.
