Ciscox notes (Anthony C. Zboralski Gaius)
Research is being done on a useless Cisco 1600 with 4 megs of flash running IOS 11.1.
Recently after writting my first cisco warez (tunnelx), I told myself hey we need to find a way to inject arbitrary code, poke and peek at the memory
on a cisco, hide interfaces, route-maps, access-lists.
Let's look around:

now you can even dump the memory with 'show memory'. Good but there isn't a write memory
