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?

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?

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?

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?

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?

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.

In a Windows log analytics workspace, search for PowerShell processes that were used to enumerate network connections. Determine which PowerShell cmdlet was executed to list active TCP connections.

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.

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

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?

On a Linux system, find any process creation record where awk is used with a BEGIN rule to launch a shell. What was the exact command invoked?

On a Windows endpoint, wscript.exe was used to run a JScript. Identify the exact script path passed to wscript.

On a Linux endpoint, process events reveal a chain of group‐enumeration utilities executed by a single session. Which utility was used to query the system’s group database?

On a Linux system, analyze the process logs for suspicious command line activity that includes a sequence of commands indicating a pipe-to-shell operation. Identify the tool that was used to execute this piped command, paying special attention to its use in downloading and running script content.

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 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, review process execution logs to see if any PowerShell sessions were wiped clean. Which command was executed to clear the PowerShell history?

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 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.

A suspicious actor appears to have removed the USN change journal on a Windows workstation. Investigate process start records to find out exactly which command was used to delete the journal. What was the full command line invoked?

A Linux system shows a process in the execution logs that fetched the machine’s name. Review the DeviceProcessEvents table to find out which utility was called to perform this hostname lookup.
