In 2012, a mysterious entity calling itself Cicada 3301 launched a series of cryptographic puzzles that spanned the internet, the dark web, and even physical locations across the globe. The puzzles, which focused on steganography, cryptography, and internet privacy, were believed to be a recruitment tool for an unknown organization. Over a decade later, no one has claimed responsibility, no official purpose has been revealed, and much of the final puzzle "Liber Primus" remains unsolved. Fearful is a podcast produced by Media Forge Studios, and releases a new episode here every Wednesday.
