Here we are given one file, warm, an ELF executable. This means If you are using windows, you will need to either get this file onto a *nix system/VM or use the provided webshell using wget, curl, or the like.

Running the file prints a message saying to pass the argument -h. And there we have the flag.

> ./warm 
Hello user! Pass me a -h to learn what I can do!

> ./warm -h
Oh, help? I actually don't do much, but I do have this flag here: picoCTF{b1scu1ts_4nd_gr4vy_6635aa47}

Solve
