Successfully decoded the last code on the wall of CIA headquarters

Two amateur codebreakers have successfully cracked the final code on the CIA's Kryptos after 35 years, opening up a mysterious story.

The fourth and final code, engraved on the bronze sculpture Kryptos by sculptor Jim Sanborn at the CIA headquarters in Virginia, USA, has finally been deciphered after 35 years. Two amateur codebreakers Jarret Kobek and Richard Byrne successfully deciphered this code. Photo: Getty.

The first three ciphers were solved in 1999. Meanwhile, the last cipher has left the world's leading decryption experts "confused" for many years despite two published hints. Photo: Buyenlarge.

Two amateur codebreakers, Jarret Kobek and Richard Byrne, discovered how to decipher the fourth cipher hidden in a document that Sanborn donated to the Smithsonian Institution's American Art Archives in Washington. Mr. Sanborn accidentally left in the file a discolored piece of paper covered with tape, containing the original unencrypted message. Photo: telegraph.

Jarett Kobek, a reporter, writer and amateur codebreaker in California, asked Richard Byrne, a friend living in Washington, to look up Sanborn’s files after hearing that the sculptor planned to auction off the final decipherment next month. Photo: wired.

RR Auctions, the company organizing the auction, estimates the decoded fragment could be worth up to $500,000. Mr. Sanborn plans to donate some of the money to charity and the rest to future medical expenses. Photo: cia.gov.

Reporter Kobek read on the auction house's website that the charts used to encode the original message were kept at the Smithsonian Institution. So he instructed his friend Byrne to take photos of the contents of the file in the hope of finding clues that would help the two decode the mysterious message that had puzzled experts for more than 30 years.

The file contained several pieces of paper taped together with the words “Berlin Clock.” This was Mr. Sanborn’s first hint of the final code, published in the New York Times in 2010 and 2014. Photo: cia.gov.

Another piece of paper from 2020 that includes the words “Northeast” is the second clue. According to Sanborn, the decoder needs to find two more phrases to deduce the final answer. Photo: cia.gov.

So Mr. Kobek and Byrne continued to search and discovered the full, clear message behind the cipher. A few weeks after the auction was announced, Mr. Sanborn received an email from the duo on September 3 informing him that they had cracked the cipher. After a conversation between the three, the sculptor asked the Smithsonian Institution to seal the file until 2075 when he realized his mistake. Photo: cia.gov.

At the same time, Mr. Sanborn also called Mr. Kobek and Mr. Byrne to ask them to sign a non-disclosure agreement in exchange for a portion of the auction proceeds, but they refused because they were concerned about being accused of participating in fraud. The auction house's website announced the news of the code being broken, but the answer has not yet been made public. Photo: kryptosfan.wordpress.com.
