Wave a flag

  • Description: Can you invoke help flags for a tool or binary? This program has extraordinarily helpful information...
  • Difficulty: Easy

🔎 Solution​

Grant execute permission to the program.

> chmod +x ./warm

Upon running it, the program suggests using the -h flag for more information.

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

Executing it again with the -h parameter reveals the flag.

> ./warm -h
Oh, help? I actually don't do much, but I do have this flag here: picoCTF{b1scu1ts_4nd_gr4vy_d6969390}
