Should you leave it open or on the defaults, it could be an attackers way in. The reason why is because it allows them to execute PowerShell scripts remotely without having to be on the server.
Take this line of code for example:. This will query the domain for all users with Smith in them and pipe their email into a text file. This would give them all of your email addresses and will certainly not be flagged by your AV.
This will list all of the domain admins within the domain and their usernames. As you can see pretty powerful stuff and the worst part….. These commands can be ran as a user as long as they can reach a domain controller Network. PowerShell is a…well….. Create a website or blog at WordPress. Share this: Twitter Facebook LinkedIn.

Windows PowerShell borrows much from the Linux environment including many Linux commands. It also includes the ability to pipe commands and link commands into a script. With PowerShell capability, Windows becomes a more powerful hacking platform, but until Microsoft makes its source code open source don't hold your breath , Linux will still be the operating system of choice for hackers.
All that having been said, we should still explore and become familiar with the Windows PowerShell for when the Windows platform is appropriate, such as when using Cain and Abel and some of the other hacking tools developed for Windows. They cmdlets are essentially single commands that accomplish sometimes more complex tasks similar to functions.
These cmdlets take the form of verb-noun, such as "get-help". Most system administrators and users are unaware that beneath that familiar Windows GUI lurks a powerful tool and engine for manipulating Windows. You can get to it by typing "powershell" into the search window at the Start or Windows button and click on "PowerShell". Once we have the PowerShell terminal open, the first thing we want to explore is how we get help. PowerShell has a cmdlet for that called, unsurprisingly, "get-help".
When we type "get-help", we receive the help screen like that above. Microsoft has aliased this cmdlet so that "help" and the Linux command " man " accomplish the same thing. As you remember from Linux, you can see the manual page for any command in Linux , by preceding the command with the keyword "man". Likewise, in Windows PowerShell, you can use "get-help" followed by the cmdlet to see the manual page.
Let's get the manual page for a cmdlet named "Write-Output". You can see that PowerShell returns us a manual page for the cmdlet, "Write-Output". As I mentioned above, "man" and "help" will both pull up the same context-sensitive information. Microsoft, recognizing that Linux system administrators are more accustomed to working from the command line and to encourage them to adopt and use the PowerShell, aliased many of the most common Linux commands into its PowerShell.
For instance, I can use the Windows command "dir" and the Linux command " ls " to get a directory listing in PowerShell. Some of the other Linux commands that are available in PowerShell, include but aren't limited to the following. There are numerous ways to get into the ISE, but probably the simplest is to create a file, right-click on it, and choose "Edit".
In this case, I created a file in Notepad called "Helloworld. When starting out in ANY programming language, it's requisite to write the ubiquitous "Hello World" program.
