Penetration Testing
by Brett Lee
===============================

I'm not an expert in the field.  But I do know it's nice to copy your bag
of tricks over to the system you are testing.

For scratch space to copy and edit your files, try this:

for a in `find / -type d 2>/dev/null`; do
  [ -w $a ] && ( echo -n "Writeable: "; echo $a; )
done

If you happen to find a place, then see if you have `vi` available.
By default, `vi` creates temporary files in /var/tmp.  If /var/tmp is not
in your scratch space, you'll need to do something like this in order to
use `vi`:

shell$> echo "set directory=/writeable/directory" > /writeable/directory/.exrc

and then one of these:

Bash> export HOME=/writeable/directory
Bourne> HOME=/writeable/directory
Csh> setenv HOME /writeable/directory

See the files in this directory for some additional examples.

What if you have no directories that are writeable, well, you can look for
a file that is both writeable and executable.  Something like this may help:

for a in `find / -type f 2>/dev/null`; do if ( [ -x $a ] && [ -w $a ] ); then
echo $a; fi; done


Obviously, these are not script kiddie tools, but instead are for
beginners interested in simple 'white hat' testing.
