Zodiac Killer.Jetty Images Enlargement / Mixed Maps The code message sent by a brutal serial killer that has never been captured has been cracked for over 51 years. The male suspect, known as the Zodiac Killer, killed at least five people and attempted to kill at least two in 1968 and 1969 in Northern California. In the first three attacks, he targeted the couple. The first two murdered were high school students who were parked in a car on their first date. In the attacks on the other two couples, he was able to kill the women, but the men survived. A male San Francisco driver was last known. During the murder, Zodiac Killer sent a series of letters to the media borrowing from the assassination. To prove the authenticity of the claims, there were unpublished details in the letters and evidence from the crime scene. In August 1969, following the murders of three of the five known, the Zodiac Killer sent almost three identical letters to three Bay Area newspapers. Each letter contained one-third of the 408-coded cryptogram, which the suspect said would reveal his identity. The killer demanded that the letters be released in full or he would be killed again. A week after the letters were sent, a couple in Salinas, California, broke the code. The simple text revealed that the Zodiac Killer was collecting slaves for later life and that he would not disclose his identity because doing so would hinder those plans. In November 1969, after killing the remaining two known, the zodiac killer sent a letter to the San Francisco Chronicle, which included a new puzzle. The cryptogram is known as Z-340 or simply 340 because it contains 340 characters. The full picture of cryptograms appears below: Advertising Since then, amateur and professional cryptographers, including those working for the FBI, have worked to break the cipher. An international team solved it until this week. “The cryptocurrency has not been solved for so long, it had a big goal on its back, and I felt it was a challenge that was likely to be solved,” Dave Orangek, one of the three who distorted the encrypted message, said by email. “It’s an exciting project to work with, and it’s on many ‘unresolved cryptocurrencies’ lists all the time.” The full text of the crack cryptocurrency reads as follows: I believe I have a lot of fun trying to catch myself, and I do not trust the case chamber because I do not believe in a TV show that brings a point about me. I feel sorry everywhere because now that I have enough slaves to work for, they have nothing when they all reach paradise, so I am dead because I am dead, I know. Decoded message squares containing what is already known about the case. The reference to the TV show and the gas chambers refers to an invitation to a talk show on KGO-TV a month ago in which someone who claims to be the zodiac killer said: “I need help. My health is not good. I don’t want to go to the gas chamber. In other communications, the killer used the same spelling for the word “heaven.” Of course, there were earlier references to the collection of slaves for later life. The FBI in San Francisco has confirmed that the cryptogram team has settled correctly. In a statement released Friday, the agency wrote: “The FBI is aware that a cryptocurrency that caused the zodiac killer has recently been settled by private citizens. The Zodiac Killer case is an ongoing investigation for the FBI San Francisco Division and our local law enforcement partners. The Zodiac Killer has threatened many communities across Northern California, and even though decades have passed, we continue to seek justice for the victims of these heinous crimes. Due to the current nature of the investigation and respect for the victims and their families, we will not comment further at this time. Orange, a 46-year-old software developer in Virginia, called the 340 Transposition cipher. Most cryptocurrencies used by computers today rely on mathematics to clear messages. Transposition cyphers, by contrast, are often monuments from the past that use rules to rearrange groups of characters or characters in the message. Transfer ciphers rearrange messages in a variety of ways. A common way is by rearranging the columns of a message. The message in 340 may have been rearranged by manipulating triangular sections cut from messages written in rectangles. Orange and his colleagues developed an app that helped him and his colleagues unravel the puzzle. In the video below, Orange gives a detailed description of the cyber and how he and his colleagues cracked it. Oranzak said he has been working on resolving 340 since 2006. Sam Blake, a mathematician living in Australia, and Jarl von Eg, a warehouse operator in Belgium. Van Eek is also the software developer behind AZdecrypt, a code-breaking application that was inspired by his drive to break the 340.
