Zodiac Killer Cipher Solved

2020-12-16 13:01

The SF Chronicle is reporting, and the FBI is confirming, that a Melbourne mathematician and team has decrypted the 1969 message sent by the Zodiac Killer to the newspaper.

There's no paper yet, but there are a bunch of details in the news articles.

Cryptologist David Oranchak, who has been trying to crack the notorious "340 cipher" for more than a decade, made a crucial breakthrough earlier this year when applied mathematician Sam Blake came up with about 650,000 different possible ways in which the code could be read. From there, using code-breaking software designed by Jarl Van Eycke, the team's third member, they came up with a small number of valuable clues that helped them piece together a message in the cipher.
