Subject: Re: IRM Demonstrates Multiple Cisco IOS Exploitation Techniques
Not quite sure what to think about this, is this a hoax?
No details are given, the captures of the "hack" show clearly a router
command "gdb kernel" which (according to cisco's IOS command lookup tool
on cisco.com) doesn't exist and which my own IOS device doesn't
recognize.
So let's not hype this too much as long we don't get better details,
regard it a some proof of concept for a well set up test environment...
