Summary


Mac.Simpsons was found in the wild in June 2001. It is the first e-mail chain letter spreading under Macintosh systems. The worm is written with AppleScript. This means that although Windows or Linux users might get copies of the virus in e-mail it doesn't do anything on their systems.

Technical Details


Macintosh users with Outlook or Entourage e-mail programs will resend the message further if they execute the "Simpsons Episodes" attachment. Additionally, the script copies itself to "System Folder/Startup Items/Simpsons Episodes". This way the worm will be executed in the each time when the system is restarted.

The e-mail message looks like this:

 Hundreds of Simpsons episodes were just secretly produced and sent out on the internet, if this   
message gets to you, the episodes are enclosed on the attachment program, which will only run on   
a Macintosh. You must have system 9.0 or 9.1 to watch the hilarious episodes, in high quality. Just   
download and open it.       
From, [your name]  
 -- To get random signatures put text files into a folder  called "Random Signatures" into your Preferences folder.  

In addition, the virus will attempt to open up a web page located at https://www.snpp.com/episodeguide.html (this page has nothing to do with the virus).
