Anti-Hacking White Papers

Unix Shell Scripting Malware

Overview Unix/Linux binary malware can be very dependent upon distribution flavour and kernel version. Furthermore, the use of binary files as a starting point for virus infection may not always be very successful - starting off with a coredump will result in a rapid failure. Unix shell scripting is very powerful too; it may control program configuration and start/kill services. Unix shell scripting has many flavours, for example Bourne (sh), Bourne Again (Bash), Korn, C and Tops C shell scripting. Also it is possible to create a completely new shell interpreter. However, the most common is the Bourne Again shell scripting, using the '/bin/sh' interpreter. A sample file might be called 'runme.sh'.
