bat obfuscation with set ***=****

#1 Post by EN3Kz » 04 Nov 2019 10:22

SET **.=S
%**.%ET .**=E
%**.%%.**%T *.*=T
%**.%%.**%%*.*% ***==
%**.%%.**%%*.*% .F.U.C.K.E.D.%***%%**.%
%.F.U.C.K.E.D.%%.**%%*.*% ..FU.C.K.E.D.%***%%.**%
%.F.U.C.K.E.D.%%..FU.C.K.E.D.%%*.*% ...FUC.K.E.D.%***%%*.*%

just an example you can mix it up with goto`s and %*%
Remember both %**.% & %.F.U.C.K.E.D.% will be read as "S"
So with two variables you can mix it up and help throw off script kitties :lol:

Still no feedback from the OP?

@bakemonogatari No escape character will help here. You simply have to use alpha characters rather than asterisks. Why? That's why:
As soon as the cmd sees sequence %* it will try to expand it to the passed arguments. If no arguments have been passed to your script, this sequence expands to nothing. *.% is printed as *. because a standing alone percent sign is automatically removed.
