It is definitely not new but from time to time information leaks thorugh the improper use of the "Track Changes" functionality in Word. But it time it is pretty havy - this time we are talking of a summary of the report written by Detelv Mehlis, the German proescutor heading up for the Hariri-case. If you want to see the whole story: http://www.gcn.com/vol1_no1/daily-updates/37416-1.html

If you want to avoid such kind of leakage, please see the KB about How to minimize Metadata in Office Documents on http://support.microsoft.com/kb/223396/ and check the Remove Hidden Data  tool on http://support.microsoft.com/default.aspx?scid=kb;en-us;834427
