RE: Millions of PDF invisibly embedded with your internal disk paths

["Thor (Hammer of God)" <thor () hammerofgod com>]

Not you too... people talking about "enough for them to search your computer" and "silent mapping of intranet."  Enough 
already.  The home path is a local path or mapped drive letter.  Not an IP or UNC.  Even if it was, 
"\\192.168.1.55\users\jsmith" is worthless.  You don't even know the source of the document. Don't we have enough to 
deal with than waste time with this?  You actually think the security team needs to be aware of this and make policies 
to scan and replace metadata in pdf's?  Why not have them start off by cleaning up Word docs just to show us they are 
capable of it in the first place. 

My homepath is c:\users\tmullen.  My IP address is 192.168.1.3.  Go ahead, map away.

Bonsai kittens, search warrants, silent intranet mapping and autonomous amelioration tools.  People have lost their 
minds.  Check the headers on people's email if you want a map of the intranet.   Meh.

If the leaked, embedded paths can be things like UNCs or IP-based 
internal server addresses, it is arguably a bit more than a privacy 
issue, allowing silent, external, partial mapping of the corporate 
intranet.

Not good if your organization is in the habit of making lots of PDFs 
more or less publicly available from many departments, etc...

Definitely something the security team should be aware of and 
(probably) making sure there are policies, and as necessary, 
amelioration tools and processes, to handle such.
