Physical Injects
In Capture The Flag (CTF) competitions, "physical injects" are challenges or tasks that involve real-world actions rather than just computer-based puzzles.
Imagine you're playing a game where you solve puzzles on a computer to progress to the next level. Now, picture a challenge where instead of typing on the computer, you have to go out and do something in the real world, like finding a hidden object or solving a puzzle in your school or neighborhood.
These physical injects can include tasks like finding hidden clues in a room, solving puzzles using physical objects, or even navigating a real-life obstacle course. They add an exciting twist to the competition because they require players to use their problem-solving skills both online and offline.
So, in simple terms, physical injects in a CTF are challenges that get you up and moving, solving puzzles or finding clues in the real world instead of just on a computer screen.
