The Zodiac case is a series of murders in which at least five people were killed and two were injured, beginning with the 1968 shooting of two young men and women near San Francisco. The Zodiac case, which is an unsolved case that still is under investigation at the time of writing the article, it is a movie released in 2007 due to strange characteristics such as the criminal leaving a message with a code written with a mysterious symbol.ZodiacIt became the subject of several movies and dramas like “.

Known as “Zodiac” (in English), believed to be the culprit in the Zodiac caseZodiacA man named (meaning) has sent multiple letters to media outlets such as the American daily San Francisco Chronicle, one of which was written with 408 symbols, hence it was called “code 408”. Is named.

The 408 code was cracked in 1969 by high school teachers Donald Harden and his wife, who said, “I like killing people because it’s more fun than hunting wild animals in the woods.” “From” “When I die, I will be reborn in paradise, and the person I kill will be my slave.”

In addition, the Zodiac also left a “340 code” consisting of 340 symbols, which was much more complicated than the 408 code, so the FBI and encryption experts worked on the decryption. However, so far the content was unknown.


However, on December 5, 2020, it was reported that the 340 code was finally cracked by a team of three amateur cracking teams, including Australian mathematician Sam Blake.

You can see the contents of the code and the process leading to the decryption by watching the following movie posted on YouTube by David Oranchak, a member of the decryption team.

This time, it was Mr. Blake who managed to crack the 340 code …


There are three people, Mr. Iar Banaike, who is a Belgian warehouse manager and also a good programmer, and Mr. Oranchak.


The three are dedicated to deciphering the 340 code “.AZdecryptIt has been developed and released for free.


This time around, it’s this AZ decryption that Oranchak and others used to crack the 340 code.


As usual, Oranchak, who was working on decryption with Blake and others, notices the following decryption statement derived by AZdecrypt. This is one of the 650,000 decryption examples generated by AZdecrypt and at first glance, it doesn’t make sense, so most people will pass it by.


However, if you look closely, you will find meaningful phrases like “HOPE THAT THIS”, “TRYING TO GET ME” and “OR THE GAS CHAMBER (or gas room)”. I will. This was a huge step forward for Oranchak and others who have seen mindless chains for years.


By cracking the code completely, Blake divided the 340 code into three sections.


Mr. Blake read these three paragraphs applying the following rule: “A symbol and a symbol that moves by two characters on the line below it are related.”


The actual code of rules used by Mr. Blake is as follows.


Entering the first paragraph ordered according to this rule in AZdecrypt did not give me any meaningful content. However, AZdecrypt has a feature that allows you to fix a phrase that already has a meaning, such as “HOPE YOU ARE”, and decipher the rest. If you use this function to figure out even more …


Significant new phrases such as “TV SHOW” have emerged.


Mr. Oranchak, who found out about this, said that he had inadvertently turned from his chair.


That’s because Zodiac had once been sentenced to appear on a television show over the phone.


Also, on the show, a person claiming to be the criminal called and said, “I don’t want to go to the gas room.” This made it highly likely that phrases such as “TV show” and “gas room” that were cracked from the 340 code were not just coincidences and provided clues for later decryption.


The full text of code 340 that Oranchak et al. Deciphered is the following. There are spelling mistakes, but when translated into Japanese, “I hope everyone who tries to catch me enjoys it very much. But I was not on TV. The difference with me is that I am not afraid of the gas chamber, because it sends me to the paradise quickly. I already have enough slaves to work for me. Others are in paradise. I have nothing when I arrive, so I am afraid of death, but I am not afraid because I know my new life, my life is enriched by death in paradise. It will be. “


Following its decryption by Oranchak and others, the FBI via the San Francisco Chronicle “The FBI acknowledges that the code in the Zodiac case was cracked by civilians. The case was in collaboration with a local law enforcement agency. The investigation is still ongoing. ongoing, “it said in a statement.

“The Zodiac incident has terrorized communities throughout Northern California, and decades later, we have been engaged in these brutal crimes,” said Cameron Paulan, a spokesman for the FBI’s San Francisco office. We will continue to seek justice for the victims. Due to the ongoing investigation and consideration for the victims and their grieving family members, we will refrain from further comment at this time. “
