gpt-4.1 vs gpt-4.1-nano KQL Benchmark

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

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.

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 Windows host, someone appears to have run a built-in network shell utility to list saved wireless network profiles and their passwords in clear text. Review the process creation logs to discover the exact command that was executed.

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

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?

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.

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.

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?

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?

On a Windows host, investigate process events to find when Task Manager was launched via cmd with an unusual flag. What was the full command executed?

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

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

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.

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?
