14-Year-Old Cracks Australian Coin's Code - in One Hour

So Australia's foreign intelligence cybersecurity agency marked its 75th anniversary by collaborating with the Australian mint to release a special commemorative coin with a four-layer secret code. The agency's director even said that if someone cracked all four layers of the code, "maybe they'll apply for a job."

A 14-year-old boy cracked their code "in just over an hour." Australia's national broadcaster reports:
The ASD said the coin's four different layers of encryption were each progressively harder to solve, and clues could be found on both sides — but ASD director-general Rachel Noble said in a speech at the Lowy Institute on Friday that the 14-year-old managed it in just over an hour.... "Just unbelievable. Can you imagine being his mum?

"So we're hoping to meet him soon ... to recruit him...."

She also revealed on Friday that there was a fifth level of encryption on the coin which no one had broken yet.
