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.

On a Windows host, registry events reveal that PowerShell modified a value under the WDigest provider. Identify the exact command line that performed this registry change.

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

On a Linux host, an activity was recorded where the local clock and timezone were queried. Review the available process execution logs to uncover what full command was run to fetch the system time and timezone.

On a Linux system, logs show that the password expiration settings file was accessed. Identify which command was executed to list its contents.

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

On a Windows system, a registry event shows the EnableLUA value under the System policies key was set to 0, effectively disabling UAC. Which utility carried out this change?

On a Windows endpoint, someone may have disabled the secure desktop for elevation prompts by modifying a registry setting. Review the registry event logs to identify which registry value name was changed to 0.

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 Windows host shows a registry write under DeviceRegistryEvents affecting the System policy path. Investigate entries where the data is set to ‘0’ and determine which registry value was modified to turn off UAC consent prompts.

Investigate Linux process or syslog records to find any invocation of the 'find' utility used to scan /usr/bin for files with the setuid bit. What was the full command executed?
