We found some crypto ciphers on our attic. Can you decipher all text and put together the flag?
This challenge was meant to be a simple task, but which required a lot of work. It gave you six encrypted messages which you need to decrypt to get parts of the key .
We have a file and the assignment to “get the password”. Ok, let’s see what kind of file it is:
$ file 7139a4ea239dcac655f7c38ca6a77b61.bin 7139a4ea239dcac655f7c38ca6a77b61.bin: tcpdump capture file (little-endian) - version 2.4 (Ethernet, capture length 65535)
Looks like a packet forensics challenge!
