Who created Bitcoin? Who built the Cicada 3301 puzzles? Who hid a backdoor in software that runs much of the internet? Press Another for a hacking fact, a quiz question, a famous hack, a hacking group or an unsolved mystery.
This section is about the history and culture of hacking, told as stories. It covers well-documented events such as the Morris worm, Stuxnet, WannaCry and the largest cryptocurrency thefts, as well as mysteries where nobody has proven the answer.
Where something is only claimed, suspected or contested, the pages say so. Attribution for state-linked attacks is based on statements from governments and security researchers, not on a court verdict. Nothing here is a how-to guide: the pages explain what happened and why it mattered, not how to do it.
If you want to go deeper, start with the full write-ups on Satoshi Nakamoto, Cicada 3301, Jia Tan and the xz backdoor, and Anonymous.
