- Who should use DSME?
- ^^^^^^^^^^^^^^^^^^^^
- If you are virus-writing beginner,you shouldn't use DSME.
- DSME is just for those people who are senior in virus-writing.
-
-
- How about the Licence ?
- ^^^^^^^^^^^^^^^^^^^^^^^
- This is a LEAGEL agreement between YOU and DARK SLAYER.
-
- You may:
-
- 1. Use DSME in your virus writing.
- 2. Free copy DSME to those who need DSME to produce viruses.
-
- You may not:
-
- 1. Use DSME on other program writing.
- 2. Modify ,or disassemble DSME.
- All rights in this part are reserve by DARK SLAYER.
- 3. Sell DSME to others.
-
-
- How powerful the DSME is?
- ^^^^^^^^^^^^^^^^^^^^^^^^^
-
- The DSME is moudule that can be include in your viruses to
- make them able to produce polymorphic viruses.
- I am preparing senior college admission test in 1994 so that
- I wrote DSME in no time. Thus,it's polymorphic effects might
- not very powerful. Guys,I won't let you down...after my test,
- I'll make it more poweful.Perhaps the next version,DSME will
- have both polymorphic and hideen features.
-
- Who wrote DSME?
- ^^^^^^^^^^^^^^^
-
- First,it's my honor to let you know that DSME is made by
- TAIWANESE who live in Taiwan,Keelung Republic Of China.(Not
- the Mainland China!!!)
- I,Dark Slayer,am high school student(17 years old).My goal is
- to build a group which can be the 5th virus group in the world.
- (Maybe you will be one of DARK SLAYER's members after you saw
- this document.) My mission is to let those who write antivirus
- program make their program better.To follow this rule,my viruses
- won't be desturctive.
-
-
- How can I get the newest DSME version?
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
- Well,about this question,we have plan to set up a BBS in Taipei
- on the begining of Nov,1993.
- You can get DSME from Nowhere Man of [Nuke] by now.
- BTW,if you have any suggestion about DSME,please drop me a line
- in NukeBeta MSG ares of [Nuke]
-
-
- How can I use it?
- ^^^^^^^^^^^^^^^^^
-
- DSME module can be used under MicroSoft Assembler.It maybe can't
- used under TASM or other assembler compilers.
-
- DSME offers you a subroutines(DSME) and a pointer of program
- ending(DSME_END). You will need DSME_END when you need to get the
- program length.
- In order to use DSME in your virus,you must include the following
- in your source code:
-
-
- VIR_LEN EQU OFFSET DSME_END
- ;This will offer you the length of the virus
-
- EXTRN DSME:NEAR,DSME_END:NEAR
-
- You can include the following when you want to encryption your
- source code:
-
- CALL DSME
-
-
- Input parameters of the crypt routine:
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
- ES => Work segment (Decryptor + encryted code ,start in ES:0)
-
- DSME's decryptor code will not over 512 bytes.
- Only you have to do is to reserve memory size (your virus
- lengh + DSME lengh + 512 bytes)
- You should notice this if your virus is resident in memory.
-
- DS:DX => Code's address to encrypt
-
- This must point to the code you want to encrypt.
-
- CX = Length of code to encrypt
-
- You can use 'OFFSET DSME_END' to get the whole lengh.
-
- BP = Offset where the decryption routine will be executed
-
- The decryption routine's offset depends on which kinds of
- file you want to infect it.(Like Friday infects COM files,
- you should set BP to 0100h)
-
- BL = Decryptor addressing mode
-
- BL = 0 Don't care addressing mode. (Used to infect COM files)
- BL = 1 Use CS or SS to addressing.(Used to infect EXE files
- BTW,you must set SS=CS)
-
- Output parameters of the crypt routine:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- DS:DX => Decryptor + encrypted code
-
- Return from DSME ,DS:DX will point to decryptor + encrypted
- code. This will make writing-function of INT 21h easier.
-
- CX = Length of decryptor + encrypted code
-
- This will make writing-function of INT 21h easier,too.
-
- Except these register mentioned above and AX,other registers won't be changed.
-
- About Stack:
- ^^^^^^^^^^^^
-
- If your virus halt system all the time and you can't find the
- problem out,maybe your stack is covered by DSME.
- I suggest you use your own stack in your virus source to avoid
- the stack problem.
-
- Final notes.
- ~~~~~~~~~~~~
-
- First, I want to thank the Dark Avenger from Bulgaria for his
- nice 'Mutation Engine' program. This fine program has been a
- great source of inspiration for the DSME!
-
- Second,I also want to thank Ruei-Chiang Huang for his writing
- on THE 3RD WAVE (Chinese Magazine) about 'Mutation Engine'
- interduction.This article cause me to write DSME.
-
- Check out the sources of DSME-GEN and DEMO to learn more about
- the DSME and how it works.
-
- Please, remember that the author of the DSME and the Dark Slayer
- virus produce group are not responsible if you use the DSME in
- an illegal or naughty way.
-
-
- Good luck.
