Jani, whose last name was not released for privacy reasons, is the youngest ever recipient of Facebook’s “bug bounty.”
“I wanted to see if Instagram’s comment field could stand malicious code. Turns out it couldn’t,” Jani told Finland’s Iltalehti newspaper.
Facebook said the glitch was fixed in February and the reward was paid in March.
Jani is too young to have a Facebook or Instagram account of his own, said he learned coding from Youtube videos and found a way to delete user comments from Instagram accounts.
“I could have deleted anyone’s comments from there. Even Justin Bieber’s,” he told Iltalehti. If he had done that he might have also won a Nobel Prize for raising the standards of the world.
Jani is thinking about a career in data security, but for now his plans include buying a new bike and a football with the reward money.
