gpt-4.1 vs gpt-5-high KQL Benchmark

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

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?

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?

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 Windows endpoint, wscript.exe was used to run a JScript. Identify the exact script path passed to wscript.

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'.

Using Linux process execution logs, identify the specific command that was used to filter loaded kernel modules for entries containing “vmw.” What was that full command?

On a Linux system, attackers may use timestamp manipulation to hide malicious changes. Investigate relevant logs to identify which file’s modification timestamp was altered by such a command.

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.

Windows systems may be probed for their password policy settings using a native command-line tool. Determine which command was executed to list the local password policy on the target hosts.

On Linux, review the process execution logs to uncover when Chromium’s bookmark JSON files were being located and the results persisted. Focus on shell commands that search under .config/chromium and write output to a file. What was the filename used to save the findings?

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.

A suspicious registry change was made on a Windows system modifying the Terminal Services DLL path. Investigate registry events to find out which DLL file name was set as the ServiceDll value under TermService. What was the file name?

An attacker has attempted to sideload code by invoking regsvr32.exe in a Windows host against a file that does not use the standard .dll extension. Investigate the process event logs to determine the name of the file that was registered.

On Linux systems, an attacker may gain persistence by appending instructions to the global shell profile. Investigate process or file modification events to find evidence of text being added to /etc/profile, and identify the exact command invocation that carried out this change.

A suspicious file modification on a Linux device targeted the ~/.bash_profile file, apparently adding a new line. What was the full command string that was appended?

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.

A Windows host shows a process launching with install-driver switches, likely signaling malicious driver deployment. What is the name of the tool that was executed?

A Linux user’s bash history was searched for patterns like ‘pass’ and ‘ssh’, and the matching lines were redirected into a new file. Determine the name of that file.

On a Windows host, an external PowerShell script is fetched and run to harvest local Wi-Fi credentials. Investigate the process execution logs to find out what script file name was downloaded and invoked.

Investigating a Windows device, you suspect a non-standard executable was launched to set up a named pipe for client-server messaging. Determine the name of the executable that was run.
