Linux Viruses - ELF File Format

Overview The use of Linux as an operating system is increasing rapidly, thanks partly to popular distributions such as 'RedHat' and 'Suse'. So far, there are very few Linux file infectors and they do not pose a big threat yet. However, with more desktops running Linux, and probably more Linux viruses, Linux virus situation could become a bigger problem. So far, Linux viruses are either prependers or regular file infectors that change entry points and modify the actual host code etc. Nowadays, the most common Linux file type in use is called 'ELF': short for Executable and Linkable Format. ELF supports 32- as well as 64-bit objects. This paper will take a look at the Linux ELF file format layout and examine some file virus infectors.
