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?

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

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

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 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.

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?

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

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.

On a Windows device, examine registry event logs for modifications under the System policies path. Determine which registry value name was altered to disable the shutdown button at login.

Review Windows process and PowerShell activity for commands that enumerate PnP entities through WMI. Which PowerShell cmdlet was invoked to perform this hardware inventory?

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.

On Linux, review file events for changes in the system-wide shell profile directory. Determine the name of the script file in /etc/profile.d that shows evidence of an unauthorized append.

On a Windows endpoint, an attacker ran a PowerShell sequence to establish a WMI event subscription using CommandLineEventConsumer. Inspect the process or script execution logs to uncover which executable was set to run by this subscription.

A Windows endpoint shows an Active Setup entry under Internet Explorer Core Fonts being altered with a StubPath value. Investigate the registry events and identify the payload that was set.

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 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 a suspicious registry change under the LSA hive. Review recent registry events to locate any new entries under Authentication Packages and determine the name of the DLL the attacker added.

A Linux system shows a shell invocation that appears to be searching for files with elevated group permissions. Using the available process execution logs, determine exactly what command was run.

A .NET tracing environment variable was turned off in a user’s registry on a Windows system. Which built-in command-line tool was used to make this registry change?

Using Linux process or syslog logs, identify the executable that was run to output the system's locale information.

On a Windows device, an attacker ran a PowerShell script to collect system settings including UI language and locale. Identify which cmdlet in the command line was used to obtain the system locale.
