gpt-4.1-finetuned vs gpt-5-nano-medium 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.

On a Linux host, a ping command was executed to test internet connectivity. Determine which IP address was used as the ping target.

On Windows hosts, look through recent PowerShell execution records to find any elevated session where remote management was turned on. What exact command was run to enable PSRemoting?

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

On a Linux system, identify the script that was generated by decoding a base64 data file and then executed. What was the filename of that script?

Linux hosts may log events when new files are added to /var/spool/cron/crontabs. Query those logs for a creation or write action in that directory and determine the file name that was added.

An attacker on a Linux host may try to enumerate installed shells by reading the system file that lists valid shells. Using process or syslog data, determine which command was executed to perform this enumeration.

On a Linux host, identify the process invocation that altered a user’s login shell. What was the full command used?

On a Windows endpoint, review process execution logs to see if any PowerShell sessions were wiped clean. Which command was executed to clear the PowerShell history?

On a Windows endpoint, commands are no longer being logged to PowerShell history, suggesting PSReadLine settings were altered. Using process execution logs, determine the exact command that was run to set the history save style to 'SaveNothing'.

On a Linux endpoint, you suspect malicious clearing of the bash history by redirecting from the null device. Explore process or file events to uncover the exact shell command that performed this action.

A suspicious actor appears to have removed the USN change journal on a Windows workstation. Investigate process start records to find out exactly which command was used to delete the journal. What was the full command line invoked?

While investigating process creation logs on a Linux device, you observe a privileged hardware interrogation step used to reveal virtualization details. Which utility was invoked?

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 Windows user’s registry was altered via a command-line tool to disable the lock workstation feature by adding a DWORD entry under the current user Policies\System key. Which registry value name was modified in this operation?

On a Windows endpoint, review the registry write events to spot when the WDigest key is altered to permit plaintext credential storage. What registry value name was changed?

In Windows process event logs, you notice both the net time and w32tm commands being executed to display the system time and timezone. Which executor name from the test configuration was responsible for launching these utilities?

An analyst reviewing Windows process logs wants to spot instances where a native time tool was repurposed to introduce a delay. Which full W32tm invocation, including the stripchart and period flags, appears in the logs?

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.

On a Linux system, logs show that the password expiration settings file was accessed. Identify which command was executed to list its contents.

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.

Within Windows process event logs, identify instances where the built-in net.exe utility is used to change a user account password. What was the new password argument passed in?

A Windows host shows evidence of a driver being installed using a built-in utility. Investigate process creation events to find the INF filename that was specified in the add-driver invocation.

On a Windows endpoint, someone may have disabled the secure desktop for elevation prompts by modifying a registry setting. Review the registry event logs to identify which registry value name was changed to 0.
