I accidentally wrote the flag down. Good thing I deleted it!
Download the challenge zip, unzip it locally, then change into the drop-in directory.

unzip challenge.zip && \
cd drop-in/
Solution
This is a successor to the Time Machine challenge. If you use `ls -a` in drop-in directory you can see the .git file which allows you to see the commits. Before looking at prior commits in the log there is a file called "message.txt" with the file contents of "TOP SECRET".
- Step 1List commitsgit log shows a commit labeled "create flag" with ID 3d5ec8a26ee7b092a1760fea18f384c35e435139.git log
