gpt-4.1 vs o3-mini-high KQL Benchmark

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.

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?

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?

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?

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.

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?

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

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, 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.

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

On Windows, review recent registry changes to detect when the MSC file association was hijacked by a reg add operation. What executable file was configured as the default command under HKCU\Software\Classes\mscfile\shell\open\command?

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

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.

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

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 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?

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?

Review Windows process execution logs to find any native utility that was used to enumerate connected drives. Which utility 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.
