Description

Can you invoke help flags for a tool or binary? This program has extraordinarily helpful information...

Process

{: width="972" height="589" } Hex Editor in VSCode

The flag is found in the file, but it is not in plain sight. Using a hex editor, the flag can be found. The word binary triggered me to use some sort of hex editor to view the file. I used VSCode to view the file, and found the flag.

Flag

picoCTF{b1scu1ts_4nd_gr4vy_6635aa47}

{: file="flag.txt" }
