open with 010 editor
which header is PDF and add its format .pdf
watch that and nothing to get ps:can use pdftotext in case of some useful string missing
`pdftotext mycat.pdf`
and we'll see
1. * 20:55 Msg1. Planing takeover.2. More details will come.3. SECT…………………f…………b.………..4. 21:00- Transmission Terminated!
Is that a clue ? I don't know
then we
```binwalk -e mycat.pdf```
get a lot of documents
put the biggest one to 010Editor
oh~ it's an another pdf
same as before
```pdftotext 6A.pdfcat 6A.txt```
we get the flag!
