How to create a simple Linux ELF virus that can infect and
propagate through other ELF executables.
The history of computer viruses dates back to 1949 when Mr John von Neumann, a lecturer at
the University of Illinois, wrote a paper:
“Theory of self-reproducing automata”.
That was just a research work, but since
then, computer viruses have evolved
dramatically. Apart from early systems, the
Microsoft Windows OS has been a primary
target for computer virus developers.
Whether this is due to the number of
people using that OS or the number
of loop holes it carries, the debate still
remains open. For the past two decades,

the popularity of the Linux OS has grown
in leaps and bounds with more and more
Web server machines running on Linux.
Using Linux on a PC or laptop is a growing
trend. Linux’s growing popularity poses
the new threat of it being vulnerable to
virus attacks. Although the success of
existing Linux viruses has been limited, the
threat still remains.
