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

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?

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.

Examine the logs from the Linux system for events related to the systemd timer activation. Identify any records indicating that a new timer unit was started and enabled, and determine which timer name was used.

During a Linux investigation, you notice processes spawning curl and wget commands that pull a script from a remote GitHub raw URL and pipe it into bash. Identify the name of the script that was retrieved and executed.

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 Linux device, a file was silently removed from the /tmp/victim-files directory. Search through file event or syslog records to identify the exact file name that was 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?

On a Windows device, there’s evidence that PowerShell history was wiped by deleting the history file. What was the exact command used to perform this action?

Evidence shows that the Windows Defender startup entry was tampered with via an elevated command prompt. Investigate registry events related to the Run key to discover which executable replaced the default SecurityHealth value. What is the name of the new program?
