I found a similar named attachment coming from DC214 - this is a sort of hacking group - they come under the Defcon Groups. This is coming under the guise of Black Security Research Group - I see no Black Security Research Group - I couldn't trace them as a company, but tracked them to http://blacksecurity.org/ - their attachment which is 'rootkit_basics.ppt' is basically a powerpoint presentation on how to design a rootkit.
On browsing their site, I am find various .ppt files that have Rootkit in the title 'BL4CK_-_Rootkit_Basics' etc.
You can probably safely open the .ppt file in notepad, just to get an idea of what is contained in there - there will be a lot of garbage (probably the bulk of it), but there should be recognisable English in there as to what the ppt is about.
