Writing Cisco IOS Rootkits

[Luca <luca () grid32 com>]

This paper is about the work involved in modifying firmware images with 
the test case focused on Cisco IOS. It will show how it is a common 
misconception that doing such a thing involves advanced knowledge or 
nation state level resources. This paper provides sound methodologies, 
shows how to approach the subject, and walks the reader through the 
entire process while providing the necessary knowledge so that by the 
end of the paper, if the reader is to follow it completely through, they 
will have a basic but functional firmware rootkit.
