A user downloaded an extension for a browser, and the user's device later became infected.

PowerShell is a scripting language and command-line shell that can be used to automate tasks and manage systems. PowerShell can also be used by malware to execute malicious commands and evade detection. The code snippet in the question is a PowerShell command that creates a new partition on disk 2, formats it with NTFS file system, and assigns it a drive letter C. This could be part of an attack that wipes out the original data on the disk or creates a hidden partition for storing malware or stolen data. References:
