- Virus Mutator V1.0 (K) KopyWrong 1992 System Violator - This is a very simply progam which adds some lines to a source code, you can choose that line yourself, but I think it's best that you use the smallest command 'NOP'. Here are the steps to do this mutation. First the program asks for a Virus Source Code Name, if you don't have any original Sources, dissasemble a Virus, this is the infile. Then it asks for a output file, enter down anything. On most disassembled files are there many lines in the beginning which not is a part of the program, them you want to skip inserting NOPs. On the next question, enter the line where the real program begins. At the end of all viruses there are some lines which is not code, it's data, maybe a text or something, here shall you not inserting NOPs, write down the linenumber where you shall stop inserting new lines. Then you have to enter how many lines there shall be between each new line, the best is to try, compile the program and try with all scanners. If it don't work, decrease the number. On the next question I think it's best you enter a 'NOP', this is the new line to be inserted. Now you only have to assemble the file, and try with all AV programs before spreading it to your enemies. I recommend Sourcer as dissasembler and TASM 2.0 as assembler, get them on almost any board. If you don't understand or want something else, contact on any Virus board in Sweden, maybe the upcoming DEMORALIZED YOUTH HeadQuarter or the Swedish Virus eXchange. System Violator - 1992 Thanks DAv and all virus writers all over the world. ( Damn, I hate writing docs, they always become so extremely lame... )
