## Write up
The given pdf is password protected.

By analysing the hexdump of the file, near to the `trailer` of the pdf, we can see the hexdump of a `PNG` embedded in a reverse manner.

Extracting this png will give the flag. Here's a simple script to extract the png

with open('deep.pdf', 'rb') as p:
	pp =p.read().hex()
	ppp=codecs.decode(pp,"hex")
	k=ppp[::-1]
with open('deep.png', 'wb') as m:
	m.write(k[203:])


Hints:
With`strings` command we can see b64 string after EOF of the pdf which will decode to `iloveyou3000` which is the password of the pdf.

On opening the pdf there is poem given. With just googling we can find that it a poem named [The Strings](https://www.poemhunter.com/poem/the-strings/) which is a hint to go back and analyse the strings
