Hack You CTF 2012 - Packets 200

less than 1 minute read

In this task, we are supposed to answer the question: “What’s the md5 of the file being transferred?”. We are given another capture file, this time containing a session with FTP.

We simply followed the tcp stream of the FTP data transferred after a RETR command was sent to the server and saved the data to a file.

After that, we ran md5sum on the file.
