Refer to the exhibit. An engineer is reviewing a .LNK (shortcut) file recently received as an email attachment and blocked by email security as suspicious. What should the engineer do next?

A sandbox permits safe observation of the payload’s behavior without assuming a specific malware family or impact. PowerShell documents that Bypass blocks nothing and produces no warnings or prompts.
