Phantasie Mutation Engine Version 1.00 Written by Burglar in Taipei, Taiwan. (95/01/12) 1. License You are free to include this Engine in anything, but don't to injure anything. Injure anything is prohibited. You are free to give it to people that will not injure anything, you can use it to make mutation virus, but the virus don't have any destruction. 2. How to use it when you want use it, you must declare below at first in code segment. EXTRN PME:NEAR Then you write your program like virus as usual. When you need to encrypt the code, you just call the Engine. Put the following instruction in your code: CALL PME You also need to supply the parameters for the Engine. They are passed in registers. Results are also passed in registers. Of course, you must link the PME.OBJ module to your program like virus! 3. Input parameters All parameters are mandatory. Description follows: ES = Work segment The Engine needs work space. On entry, ES must point to a free segment. It will use the first 512 bytes of it PLUS length of the code that will be encrypted. DS:DX => Code to encrypt On entry, just set DS:DX to point to the code you want to be encrypted. CX = Length of code to encrypt On entry, just set CX to the length of the code you want to be encrypted. BX = Offset where the decryption routine will be executed The Engine needs to know what will be the value of IP when the decryption routine will take control. For example, if your program which want to be encrypted is a COM file, and adds itself BEFORE it, you must set this value to 100h. 4. Results The Engine returns the following values in registers: ES = Work segment The ES value is preserved. DS:DX => Decryption routine + encrypted code DS:DX now points to the decryption routine + encrypted code. CX = Length of the decryption routine + encrypted code CX now has the summary length of both the decryption routine and encrypted code. (always origin length + 512 bytes) AX = 0 AX now is set to 0. 5. Final Notes Well, that's for now. No time for more. Look at the demo program PME-GEN.ASM to learn how to use it. Pass the Engine (all files together in an archive) to programmers and who want research it. Greetings to all programmers Burglar Taipei, Taiwan.
