Almost instantaneously, the decompiled source code is displayed in the application Figure 12 and the plain-text script is dumped to disk as a.You seem to have CSS turned off. If you are dealing with a compiled scriptsimply drag-and-drop the AutoIt Interpreter executable i. Bottom line, any time you have the opportunity to obtain and analyze the original source code, you take it! Exe2Aut is an application that enables simple drag-and-drop decompilation of compiled AutoIt scripts. With the standalone executable, the malicious payload will be presented as a single. This is just how this particular miscreant decided to trick the victim into running their malware. Note that the method for getting the unsuspecting victim to execute the malicious AutoIt payload will likely differ between samples. We can see how this malware is executed by inspecting the specified targets of the shortcut files also present within the same directory Figure 6.ДЄs expected, the malicious code is executed by passing in the compiled AutoIt Script WinddowsUpdater. The contents of this particular script is shown in Figure 5. In the example provided in Figure 1, this would be WinddowsUpdater. In order for it to facilitate malicious code execution, the interpreter must be fed a script. The AutoIt interpreter, by itself, is benign. Figure 4 shows that the hash for WinddowsUpdater. Third, you can compare the hash of the file in question to the hash of the actual AutoIt3. Second, if you inspect the version information for this file within PEStudio, you will see multiple references to AutoIt medium fidelity Figure 3. The first sign that is the case is the icon for the file, which is the AutoIt icon extremely low fidelity Figure 2. Here is an example of one such malicious sample.

I will, however, attempt to provide you with a starting point by showing you how to get from a compiled AutoIt binary to a plain-text script. Unfortunately, there are way too many different ways that malware authors have leveraged AutoIt for me to write a one-analysis-fits-all post.

Hi there, When using the obfuscator, my project is marked by 13 AV's as a virus according to VirusTotal. It's easy! Already have an account? Sign in here. Sign up for a new account in our community.

The installer now includes both 32 and 64 bit versions. Be sure to read and follow the forum rules. Just checking a bit deeper is a better alternative although we will still be plagued with the occasional file being improperly flagged.

I should look at the next update to see what has been changed but the last time I looked they had 40 new AutoIt scripts within 2 months that were definitely a virus so I don't blame them for being a bit cautious nor do I want to see them relax the rules. That can be a pain in the arse to keep up with but eventually the companies involved do start to pay attention to the method they use to detect a virus in a compiled AI script. Or you might try to not use UPX to compress the code. If you 'tone it down' to use more simple obfuscation only variable and function names changedstripping comments, and compacting your code removing double newlinesthen I think you'll have less of a problem with AV marking your script. Thank you for pointing me out where the search box is, however, there is still no post which says how this can be done, except the fact that that guy didn't obfuscate but saved his data in a encrypted dat file. I don't want to use that obfuscator, since I don't want my users to think it might possibly be a virus. I'm just having issues why obfuscating my code will mark it as a virus. If you search the forum these very questions have been asked and answered many, many, many times. You are treading on very dangerous ground here. However, using this my project can be decompiled quite easily although -snipped- failed todo so, for some reason - I don't know why though - something about detokenising.
