In my previous post I covered my “Classic” Mac OS emulator set up. One of my goals of getting the emulator set up was to be able to look at and analyze viruses that affected older versions of Mac OS. I think taking a look at old viruses is interesting for two reasons. First, it provides a good overview of 68k assembly. Second, it provides an interesting perspective on the history of malicious software. The first virus I decided to look at is called INIT 29.
