Search engines
Around 2:19 you can see the file name in the top of the pdf reader. Putting this between double quotes let's the search engine search for that exact phrase:
Google
I also tried Bing and Duckduckgo, but they don't give anything either.
Meta search engines
If we try meta search engines (special search engines that combine the results of multiple normal search engines):
Dogpile
I also used Excite and Deeperweb, but they don't result in anything either. Besides using the exact phrase method, I used the following:
"inurl:no inurl:malware inurl:here filetype:pdf"
(without double quotes), but that also gives nothing. Because of this I think an exact copy of the document he uses isn't available on the internet.
Let's mess around
Wikipedia tells us that heap sprays can be implemented using JavaScript and/or images. Both of which can be used inside a pdf file. If you're really interested, you could search for general tutorials on heap spraying and on using JavaScript inside pdf documents and try something out yourself.
