Found in the wild, on a server of one of Joost’s employees, the file is a PDF presentation of some of Joost’s technicalities. But simply selecting the text, copying and pasting it to notepad reveals a whole lot more data. Yes, some of it is definitely not meant to be seen by the public; it includes a number of Joost’s upcoming deals with media content providers.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.google.com/reader/shared/11461281655036520773">PDFs are usually used by the government precisely because they’re quite safe</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.google.com/reader/shared/11461281655036520773">guess is that in this case, someone created one Powerpoint presentation. Then opened the same document, and created new boxes on top of old ones, which thus became invisible. And after that, (ironically) probably to be on the safe side, they converted the entire thing to PDF thinking that the old data is gone. But, it’s not - it’s simply not immediately visible.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/60034200-0E99-44F7-85EA-CF2951525A2A/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
