Re: hack that changes root to Root

This is from the command vipw, and "root" was "Root", changed all 'root'
ownership changed to Root.
Only 3 people know roots passwd, and a look at their keystaoke history
indicates none changed root to Root

Two things came to mind while reading this thread:

(1) Remember that the ownership is really user ID 0, and 'ls' simply looks up 
the username based up on this UID; trust me, I've changed 'root' to 'god' so 
that 'god' now owns the system, mostly for levity in the office.

(2) Many escape sequences from function keys, including 'Insert' have a tilde 
'~' within them; in 'vi' the tilde changes case of the current character.

I'm not saying you're not seeing a hack.  I'm simply suggesting that this may 
be a simple clumbsy-fingered mistake instead of an intrusion.

Happy hunting,
-Bill
