Whale Watching

by vishalananth

Where is the flag? It is not down on any map; true places never are.

Hunt down: johnhammond/whale_watching

Solution

The challenge name and the search string format hinted at a docker container. So I went to Docker Hub and searched for johnhammond/whale_watching. We got the container!!, going into tags and clicking on latest, we get the history of the container which contains the flag.

Flag

flag{call_me_ishmael}
tags: OSINT
