and get the resulting pdf file.

- now the email says that the password for the pdf is a postal code.
- this means the password is five digits, we can brute force this.

#### brute forcing the pdf password

- first extract the hash using [pdf2john](https://github.com/truongkma/ctf-tools/blob/master/John/run/pdf2john.py)

![image info](../images/cybersecurityrumble/pdf_hash.png)

- your ouput from pdf2john should look like this, the highlighted part is what we're interested in.
- we can now crack this in hashcat using the following command.
- `hashcat -a 3 -m 10700 -o out.txt '<hash>' ?d?d?d?d?d`
- `-a 3` specifies attack mode #3, bruteforce
- `-m 10700` this is the hash type, optional because hashcat can autodetect hashes
- `-o out.txt` specifies the output file
- `?d?d?d?d?d` a mask of 5 `?d` chars which refers to digits 0-9
- now if we look at out.txt, we can see the cracked password

![image info](../images/cybersecurityrumble/hashcat_result.png)

- now we can use this password to unlock the pdf which contains the flag
