Zodiac Cipher Cracked
I admit I don’t pay much attention to pencil-and-paper ciphers, so I knew nothing about the Zodiac cipher. Seems it has finally been broken:
The Zodiac Killer was a serial killer who preyed on couples in Northern California in the years between 1968 and 1970. Of his seven confirmed victims, five died. More victims and attacks are suspected.
The killer sent four messages to newspapers in California’s Bay Area, only one of which has ever been decrypted. This first message split into three parts claimed Zodiac wanted to kill victims so that they would become his slaves in the afterlife.
The 408-symbol cryptogram was cracked by Donald and Bettye Harden of Salinas, California.

EDITED TO ADD (8/5): Solution seems to be a hoax.
