gpt-4.1 vs gpt-4.1-finetuned 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.

Identify the PowerShell cmdlet used on Windows to format and display the raw volume bytes after an attacker read the boot sector via a DOS device path.

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?

A Linux host’s Syslog shows a shell-based network discovery script ran multiple commands. One of them listed current TCP connections. Which utility was invoked?

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, review process creation logs to uncover when a built-in utility was used to reveal ARP entries. What exact command was used to list the ARP cache?

A Windows host shows a process launch with an extremely obfuscated command line that dynamically builds and invokes code at runtime. Which process name was used to execute this payload?

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.

A Windows host executed an ICMP-based network reconnaissance using a looping instruction in cmd.exe. Identify the exact command line that was used to perform the ping sweep.

A user launched a Windows command prompt and executed a built-in utility to enumerate all active network connections. Using process creation logs, identify the exact tool that produced the list of current connections.

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?

In a Windows log analytics workspace, search for PowerShell processes that were used to enumerate network connections. Determine which PowerShell cmdlet was executed to list active TCP connections.

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

You suspect malicious persistence via scheduled tasks on a Windows endpoint. Review the process execution logs to identify the built-in utility used to register tasks at logon or startup. What is the name of this utility?

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?

A Windows endpoint recorded a command-line activity through cmd.exe that lists all running processes. Determine which built-in tool was executed to perform this action.

On a Linux endpoint, process events reveal a chain of group‐enumeration utilities executed by a single session. Which utility was used to query the system’s group database?

On a Linux system, you suspect someone erased their command history by linking the history file to /dev/null. Investigate process events and determine which utility was executed to achieve this.

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

Investigate Windows process execution logs for a PowerShell cmdlet used to list group members. Look for entries where a group name is provided after a '-Name' flag and identify which group was queried.
