Tenbagger #Challenge description: I think I took it too far and made some trades and lost everything. My only chance to fix my account balance is a tenbagger. We are given a pcap and open in Wireshark. It contains a lot of what looks like normal web browsing. But somewhere in there are a few FIX messages. FIX is the Financial Information eXchange protocol.
