This one was a pain in my butt.

Confirmed working, solved by:

pdf-parser.py -a pdf pdf-parser.py --object 2193 --raw --filter pdf > outfile dd bs=337 skip=1 if=outfile of=newfile (remove extraneous pdf-parser junk) binwalk newfile binwalk -e newfile file * mv 38E50 38E50.tar tar -xvf 38E50.tar base64 --decode secret.txt > file xxd file (look at magic number to determine its JFIF) open image

Difficulty: 7
