Binwalk
30 points Easy

Here is a file with another file hidden inside it. Can you extract it? https://mega.nz/#!qbpUTYiK!-deNdQJxsQS8bTSMxeUOtpEclCI-zpK7tbJiKV0tXYY

binwalk is unintuitive, with a misleading man page. It also extracts the ghost png data as a .zlib file, which is misleading. foremost extracts the hidden file easily.

Thanks for the hint, kind stranger.
