10/ The payloads appear to be zip files containing a legitimate exe and a (likely) sideloaded dll. Sadly, the sample wasn't publicly available, and VT didn't have a clear verdict on what it was. So we'll leave the analysis here and continue another day :)

9/ We can continue to apply the same concepts (identifying and searching strings) to locate additional pieces of the infrastructure. We can also search on the final URLs and determine the payloads.

8/ This leads to a bunch of new and interesting results. Some of them are almost identical (but with different file names) and others follow the same general logic but with quite different code.

7/ Pivoting on the Second Stage Content 👀. The second stage downloader contains a relatively unique combination of strings. We can pick some and query them to find similar code. I chose to use bitstransfer, expand-archive and start-process.

6/ We can find out more by searching the domain found in the downloader code. This reveals that the payload is another downloader. The code tries to download a zip and exe via bitstransfer, and then creates a run key for persistence.

5/ This works well - and shows many sites hosting similar suspicious content. Here we can see another site hosting the same text, but with a slightly different payload. The download function is the same, but the URL in the downloader is different.

4/ Now let's try and find similar sites. The previous text is relatively unique - so we can use it as a pivot point. Anything in the text tab can be searched - so let's try the "Press Windows Button "" + R" string.

3/ The "malicious" code can be found inside of the DOM content tab. This reveals that the payload is a simple powershell downloader
