PowerShell is an advanced systems administration and automation framework, primarily used in Windows environments, but now available on Linux and macOS. It is characterized by its ability to execute text commands "cmdlets", manipulate system logs, and manage networks and processes automatically. In cybersecurity, PowerShell is used by security teams and attackers alike, where it is exploited to perform fileless attacks, load and execute malware directly from memory, and control systems remotely. To protect against these threats, it is recommended to disable Execution Policy for unsigned commands, monitor Event Logs, and use threat detection tools such as AMSI "Antimalware Scan Interface".
