AutoIt and Malware: Compile or just run scripts with AutoIt3.exe?

Recommended Posts

TXTechie

Hello Everyone!

Now that I've decided to begin using AutoIt as my standard template "wrapper" for deploying software and automating changes on computers within my work environment, I want to ask the community whether you think I should deploy my software packages as compiled executables, or should I just include the main AutoIt executables (AutoIt3.exe & AutoIt3_x64.exe) and then call the software package in my software deployment solution via the command-line (for example: AutoIt3.exe Flash-11.6.au3)?

The primary reason for this question is based on the AutoIt and Malware link on the AutoIt Wiki. While, AutoIt executables are not currently being flagged as false positives by our current Anti-Virus and Anti-Malware solution, I'm concerned about the potential scenario where a false positive occurring again at any time in the future (for any number of reasons) disabling all software deployments within our company because I've chose to use compiled AutoIt scripts for my standard deployment mechanism.

What are your thoughts?

Hi, TXTechie. Besides AutoIt, what method of deployment are you using (Altiris, SCCM, A.D., etc.)? I always always always suggest you take the time to repackage applications into MSI format, as it gives you much more flexibility with the install. Beyond that, however, it really depends on the method of deployment.

Hi JLogan3o13,

Well, I've been in Systems Management (software packaging and deployments) for 14+ years now and there are two primary methods for software packaging and deployments: 1) drive the installation using the native installer and 2) repackaging everything to Microsoft's Windows Installer (MSI) technology. I am in the 1) camp, so I create a script "wrapper" to drive the native installer (whether legacy or MSI) and then automate any other desired post-installation configurations as desired.

So, since I don't use Flexera Software's InstallShield tools - I've been deploying software using a script as a wrapper (currently VBScript, but I've decided to switch to AutoIt). This is why I'm asking the question.

My company uses CA Software Delivery as our software deployment solution (I have previously used Microsoft's SMS [now SCCM], Novell ZenWorks, what used to be called Marimba, but is now BMC BladeLogic Client Automation and Dell's KACE KBOX).

If you have access to your company's antivirus software on the server level, you can whitelist the installation location of your software.

Also, I have found that compiling with options and unchecking UPX compression reduces false positives.

My experience "in the wild" with home pcs and having to deal with multiple Antivirus products with multiple configurations is you can't trust them not to kill AutoIt programs.

As you (unlike I) have control of your environment,

Why not install "AutoIt3.exe" somewhere permanently on your computers.

Then associate "a3x" with "AutoIt3.exe".

That way you don't have to bundle AutoIt3 with everything, you avoid the possibility of false positives completely and the AutoIt program (a3x) isn't plain text visible.

Just my 2c worth.

abberration - The problem is the location of the deployed software will be different and growing, I don't want that management nightmare. I thought that I had read another post here in the forums stating that using any other setting except for the default UPX compression setting of Normal would change the file attributes of the default AutoIt compiled executable - is this true?

storme - Since I am also the person in control of the standard workstation clone image, I have thought about including the AutoIt3_x64.exe on our standard Win7 (64-bit) image build - if I go the route of just executing scripts (rather than compiling). However, the less than 1 MB size of each of the AutoIt executables is not a big deal. I don't really care about the visibility of my scripts (especially since I've been using VBScript files for years), but I like the idea of having less additional files by compiling to the a3x format (I had to look that up in the help file, as I was unfamiliar with that) in that it can incorporate all include and FIleInstall files. Plus, I have the added ability to make my scripts a little more secure from easily prying eyes - especially if I may include some more confidential info in some of my scripts in the future (I know that this is not really secure, but is just secure from those who aren't interested in really trying to hack the scripts). Thank you, very much, for the additional information, storme!

 

Does anyone think I should worry about this and just go ahead and use fully compiled scripts to executables for all of my deployments?

      Hi,
      I have a situation where I need to make one request to get a kind of pre-logon page, then click a link on that pre-logon page, which then returns a login form page, and then fill in information in the form page and submit it.
      How can I handle that using AutoIT?
      I can get the AutoIT script to tab to the link, then send an ENTER, which then causes the FORM page to appear in IE.  However, I cannot seem to get the form object from the FORM page (_IEFormGetObjByName fails when it searches for the form).  Why is that, and how can I get the AutoIT to process the FORM page?
      Thanks,
      Jim

      Hello friends, I have a simple question, can I have a variable that is not reset, even if my program is closed?
      That is, I want to make a program that can only be opened once, have a variable $ ini = 0, when it is opened for the first and only time it becomes $ ini = 1, so that it can not use the program a second time, as if it was a test software.
      I do not want the variable to depend on a reading of an external file that is easily manipulated. Thank you.

      My program has to first search for names in Column D that do not match up with column C. I got that search to work using arrays. It was slow and I could not figure out how to delete them so I just manually put coded the names that do not belong. I found their cell location but I do not know how to store that location and delete it.
      This is what I have so far.
      Local $NameToDelete1[6]  = _Excel_RangeFind($OpenWorkbook, "Smith, Bill") _ArrayDisplay($NameToDelete1, "Excel UDF: _Excel_RangeFind Example 1", "", 0, "|", "Sheet|Name|Cell|Value|Formula|Comment") _Excel_RangeDelete($OpenWorkbook.ActiveSheet, $NameToDelete1[2], $xlShiftUp)  
      Please help, I wanted to have this program done yesterday but I did not see this problem until yesterday.

      So Im trying to make a simple 2d game and make some sort of collision detection so why not to make a 2 dimensional array but i have no clue how  to write it in multiple lines
      Global $map[5,5] = [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0] something like this but it doesn't work

      #include "..\Include\Array.au3" #include "..\Include\File.au3" #include "..\Include\AutoItConstants.au3" Local $aRetArray Local $sFilePath = "n.csv" _FileReadToArray($sFilePath, $aRetArray, ",") ; _FileReadToArray($sFilePath, $aRetArray, $FRTA_COUNT, ",") _ArrayDisplay($aRetArray, "Original", Default, 8) The above code shows two versions of _FileReadToArray and both don't work as expected.
      The first one doesn't use the comma as a delimiter. (so I get a single column array)  I tried adding "Default" between $aRetArray and "," then it told me it had an incorrect number of parameters. 

      I looked again at the documentation:
       
      #include <File.au3> _FileReadToArray ( $sFilePath, ByRef $vReturn [, $iFlags = $FRTA_COUNT [, $sDelimiter = ""]] )
      And I with or without the flags params I should be getting a 2D array due to my file being a csv. 
      I then tried a regular flag, $FRTA_COUNT, and it tells me that I'm using a variable $FRTA_COUNT while it's not declared. Tried putting in 1 instead and it told me again, incorrect number of params.
