100071 0x186E7 End of Zip archive, footer length: 22OK, There are quite many files hidden.
Let’s extract them.
binwalk -e Forensics\ is\ fun.pptmThen we get the directory called _Forensics is fun.pptm.extracted
Let’s see what’s inside.
~/_Forensics is fun.pptm.extracted/ppt/slideMasters$ ls
_rels hidden slideMaster1.xmlFound the file hidden! What’s written inside it?
strings hidden
Z m x h Z z o g c G l j b 0 N U R n t E M W R f d V 9 r b j B 3 X 3 B w d H N f c l 9 6 M X A 1 f QWe got some lettes. Maybe it’s encoded?
cat hidden | tr -d " \t" | base64 -dI base64 decoded it and got the flag.
