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?

On a Linux system, review process execution records for any shell process that set an environment variable containing executable code and then piped it into another shell instance. Determine which environment variable name was used to store the script content.

On a Windows endpoint, commands are no longer being logged to PowerShell history, suggesting PSReadLine settings were altered. Using process execution logs, determine the exact command that was run to set the history save style to 'SaveNothing'.

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.

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

On Windows systems, identify when the built-in Shadow Copy utility is used to enumerate existing snapshots. What was the full command executed?

A Windows system shows a cmd.exe process spawn that appears to have been used for environment discovery. Review the process creation records to identify the exact command the adversary ran to enumerate environment variables.

On Windows systems, disabling RDP via the registry generates registry write events. Investigate registry event logs for modifications under the Terminal Server configuration path. What is the name of the registry value that was changed to disable Remote Desktop Protocol?

On Linux, review the process execution logs to uncover when Chromium’s bookmark JSON files were being located and the results persisted. Focus on shell commands that search under .config/chromium and write output to a file. What was the filename used to save the findings?

Investigate Windows file creation logs to uncover any new executable added directly to the System32 directory, which may indicate a UEFI persistence implant. What was the name of the file created?

On a Windows system, identify any PowerShell Test-NetConnection executions against an uncommon port. Which port number was checked?

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 notices a PowerShell process on a Windows host that appears to be checking SMB connectivity. Which PowerShell cmdlet was executed to perform this outbound port 445 test?

Review Linux process execution records for any commands that list TCP metric cache entries and filter out loopback interfaces. Which utility was used?

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 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.

Analyze Windows process events for any schtasks.exe commands that created a new task invoking PowerShell. What is the name of the .ps1 script specified to run?

A Linux host briefly hosted an HTTP service under /tmp. Examine process creation logs to determine the exact python3 command that was used to start the server on port 9090.

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.

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 host, find any scheduled task that was registered using PowerShell native cmdlets instead of schtasks.exe. What was the name given to the new task?

A malicious actor may attempt to list running processes on a Windows machine using a WMI-based command. Review the process creation events to find out which utility was invoked to perform this enumeration.

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

An attacker on a Linux host may try to enumerate installed shells by reading the system file that lists valid shells. Using process or syslog data, determine which command was executed to perform this enumeration.

On a Windows device, review the process execution logs to find instances where a built-in listing tool was piped into a string filter. Identify the process name that the attacker was searching for.
