Designed for the DEF CON 34 hacker conference by EFF artist Hannah Diaz, each sticker measures approximately 4.25" across and features a holographic center. Don’t miss the link to an online puzzle incorporated into the design! With the strength of community and the spirit of curiosity, we can hack anything.
Many thanks to our puzzlemasters Aaron Steimle (AKA Elegin) and Kevin Hulin (AKA CryptoK).
