VBScript requires a file for its source code. You want to specify stdin as the "file", but there is no mechanism to do that. So the answer is no - you cannot generate and run VBS code from the command line without using a temporary file.
Most people use a batch script to write temp VBS code, execute, and then delete the temp code, as PA has demonstrated. I have discovered a mechanism to embed the VBS code within the batch file, without the need for a temporary file. But it is not very pretty. See Is it possible to embed and execute VBScript within a batch file without using a temporary file?
It is much cleaner to embed JScript within a batch file. Learn more. There's any way to run vbscript directly to wscript or cscript command line Ask Question. Asked 7 years, 5 months ago.

Luckily Windows provides many built in tools to help you execute code while leaving very little evidence behind. A list of ways to execute code, including examples, are shown below. If you are going to drop files, then drop utilities to help run code as opposed to dropping the payload itself.

CScript is the console version, WScript is the Window version. Neither version supports scripts being supplied on the command line, instead a file must be created containing the script or a funky bat file wrapper. Example: cscript. Echo "test" forfiles.

Imagine a cool Web GUI feel free to leverage Jquery or other libraries embedded with a cool feature you already have programmed in Visual Basic. No need to install or open Excel! What is more HTA applications are simply text files with a HTA extension, hence, anyone can easily open and edit them in a simple text editor.
Neat right? Interested — read on. Today I wanted to showcase a simple HTA example. There are tons of VBA developers out there currently. These are often persons who started their developer journeys as analysts or simply Excel powerusers. At some point in time Excel native features are not sufficient to tackle some complex tasks and drive users to learn VBA.
It is quite an easy step often as, it is important to remember that Excel has 2 important advantages over other programming languages:.
Like VBA? You will love HTA! (HTA example using VBS)
Without having to install any additional software, any analyst or other corporate person can use VBA to achieve automation of certain tasks. In a series of posts I will want to encourage some VBA devs to explore some alternatives and new programming possibilities. HTA is the abbreviation for Html Application.
See the Wiki page for more details. Well now, some might say, is it simply a HTML file then? Well, hta file have elevated security privileges allowing them to run like regular desktop apps! HTA can run like desktop applications being embedded in Internet Explorer instead of e. Excel or Word in case of VBA. Additionally as these are HTML files you can build a rich user interface and a much more pleasant user experience. From my experience many VBA developers refrain from learning other programming languages, noticing that basically they build roughly any solution or automation resorting only to VBA.
This is a common trap due to which many MS Office-based monster-complex solutions are developed which should not have seen the light of day.
What Is Mshta, How Can It Be Used and How to Protect Against It
I have seen many monsters… from complex BI models calculations running for hours to … complex databases shared by multiple users at the same time oh the horror! Although all these solutions were quite amazing they pushed the limits of VBA more than they should. Rather I would like to show some alternatives.
The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. In Python you are not obliged to use a file, you can specify -c " Can I achieve the same result with vbscript?
I've seen solutions that need you to use a batch script, But what if I am on a system with zero writing permissions? This is of course a fantasticly insane hack and on a system where you are not even allowed to create a file I am not sure if mshta. Maybe you can also find additional inspiration from this thread the mshta solution is also posted there. Although mostly batch related it is imo a great compendium of several really crazy ways to fool windows into executing vbs code.
No, the interpreters shipped with Windows wscript. If you can't create a file anywhere you're out of luck. You need some kind of wrapper script to transform the argument into something that VBScript interpreters can execute.
However, that won't work correctly, because double quotes aren't preserved in the arguments. If you ran the above script like this:. Echo foo instead of WScript.
Echo "foo"and I was unable to find a way to escape nested double quotes so that they're preserved in the argument. What will work is a batch script that writes the argument to a temporary file, and then executes that file with a VBScript interpreter:. If you wanted to replicate Python's interactive mode you could use my vbshbut that would still require the ability to create a file somewhere. Learn more.

I run the following line successfully: 'mshta vbscript:InputBox "message","title","input" window. For console output you need cscript. Named If. Exists "c" Then ExecuteGlobal. Item "c" End With However, that won't work correctly, because double quotes aren't preserved in the arguments.
Echo "foo"" it would effectively execute the statement WScript. Echo "foo" : WScript.There is a growing trend for attackers to more heavily utilize tools that already exist on a system rather than relying totally on their own custom malware.
Alternatively, a file with a. There is no shortage of easily accessible repos to help someone quickly generate a payload to use mshta.
It can also call code registered inside of com scriptlets. One of my favorite tools to look for examples is app. It is an interactive online sandbox and is a great resource for finding new samples. As you can see, there is no shortage of samples to go through. Another interesting detail is we can see several different file extensions used outside of the standard. Is that true though? Here we can see it has a dubious name of windows-update.
This looks to be a binary embedded within an. We see multiple file extensions used in the name to try and fool end users into thinking it is a picture. We can also see the sandbox believes this is not malicious based on its scoring. Luckily, we can look at the PowerShell code that it spawns and get a better idea.
So, mshta can also be used to execute vbscript and WMI to break the process tree chain and launch PowerShell. One of the easiest things you can implement is to change the default applications for files with an. If you are a McAfee customer, McAfee Endpoint Security ENS provides ruleswhich is now enabled by default, and that can be enabled in ePO to help protect your environment against malicious mshta abuse.run vbscript programming on windows cmd by cscript command ('HelloWorld')
You should also spend some time exploring where abusable native binaries like mshta. If there are no business needs that require it, blocking it outright is advised.
Declare your object as a global variable in this case 'objExec'then when you run the. When you are ready to close your new HTA run using that exec method, just use objExec. In any case, you can use the terminate method to close the referenced object you created when you ran the exec method.

But that other script can take some time to finish so i cannot put a Timer on the HTA because i'm never sure how long the script will take to execute, so heres what i'm trying to do: Call my Working HTA, Execute the script and wait for it to finish, Close the Working HTA.
