This is a polymorpic worm is written in Batch script with the extensions Windows 2000/XP (cmd.exe). The worm contains two parts: polymorphic generator and main body. The polymorphic generator reconstruces the main body on each start of batch file. The worm creates its droppers with the files: SPTH.BAT and C:\MIRC\SATURN.BAT. It also creates the script file C:\MIRC\SCRIPT.INI. The script sends worm dropper (SATURN.BAT) to each user who joins the infected channel. The worm also rewrites batch files into WINDOWS directory. The worm contains the comments:

 I think, you are looking at the code and think: "What the hell is this?"|
 The answer is: A Windows XP Batch polymorph virus :D                    |
 WinXP is using a program named CMD.EXE instate of COMMAND.COM for DOS   |
 You're able to make the really nice things with CMD which you wasn't    |
 able to do it with COMMAND.COM.                                         |
