anything that would've worked 10+ years ago (for edu. purposes ^^)
i built a pretty plain 'morphic batch script' once, kind of based on the _! batch virus...
had a top section based on variable factorial mapping...
something like this (from memory)
Set _!A = "_!B"
Set _!B = "_!C"
... bout 6 of these
then to morph the section was like echo set %%_!A = ""%%_!B"" >> newfile.bat
Sadly, that was the best bit i think =(
The rest of the script was maybe 5 sections which got moved around, but always executed in the same order via Goto's and section names eg goto _!A / ... / _!F
kind of a hash - morph batch virus i suppose...
pretty useless as a virus really unless you cart .bat files around a lot.. Maybe if it got on a usb stick or something ;)
lol funny how there is no middle ground...
anyone who can do some shitty hack is leet, (therefore far too paranoid to say anything here), and everyone else is noob (and just not saying anything is probably the smarter option) ^^
