In this milestone 100th episode, Lucas and Luna dive into a controversial but real use of on-device AI: password cracking. They explore how apps like HashCat and John the Ripper leverage local neural networks to brute-force or guess passwords billions of times per second, all on a smartphone. The discussion centers on a 2025 study from Georgia Tech showing that a flagship Android phone can crack an 8-character alphanumeric password in under 4 hours using a distilled neural network. Lucas explains the technique—hash matching via a recurrent neural network trained on leaked password databases—and Luna questions the ethics and implications for user security. The hosts also touch on how this same technology is being repurposed for legitimate password recovery and security auditing. A sobering look at how powerful on-device AI has become.
