o3-high vs o3-mini-high 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.

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?

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

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.

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 system, an attacker used the command prompt to remove one or more default administrative shares. Which share names were deleted?

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?

A Linux host was used to collect various system release files and kernel details, writing them into a single file under /tmp. What was the name of that output file?

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?

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.

On Windows, an elevated SecEdit.exe process was observed exporting the local security policy. Review the process execution records to identify the name of the text file where the policy was saved.

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.

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.

Windows registry events show that a new key under the Active Setup Installed Components branch was added to launch a payload immediately via runonce.exe. Which component name was created?

On a Windows host, sift through registry modification events targeting HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\System\\ConsentPromptBehaviorAdmin. What new value was written to disable the admin consent prompt?
