When you fill a PDF form and save, informations can be embedded in the PDF. However, some PDF viewers don't show the filled values, which can lead to an accidental leak of information, even after double-checking!

Here is a hand-written PoC https://corkami.googlecode.com/svn-history/r1936/trunk/src/pdf/PDF_form_leak.pdf

Technically speaking, the filled values are the /V string fields in the /Annot objects.

Whenever I really wanted the job, I failed.
Whenever I was "let's just try and see", I got the job.
--> Just be yourself !

This is true for all job positions and applications in my life, even before Corkami (and posters, etc...) existed.

I wrote a blog post on storing passwords & security.
(how many references can you find ?)
If you're storing passwords like a secret list in a chest, then as soon as the chest is open, game over!
