Why did MyDoom create a "Message" text file with random characters?
I was reading into the 2004 MyDoom worm at a few sources.
The worm author seemed inexperienced in C++, with reviewers pointing out bugs in the code that had not been properly tested.
What caught my attention, was that MyDoom creates a "Message" text file full of random data, and even opens in Notepad. This can be seen in the source code, and within the Wikipedia article here. It was purposely done, with a function to create random text, so it was not an accident.
the sample creates and opens a text file called Message full of garbage at the Temp Directory C:\Users<username>\AppData\Local
What was this file for?
