**Summary**
Out of Time was an easy-rated hardware challenge in this year’s Hack The Box University CTF. We’re given a python script to talk to the hardware running on the other side, and everytime we submit a password, we’re given a NumPy array of the power trace. We can leverage this to “brute-force” the password, by means of a power analysis, observing irregular spikes when we input something correct. Follow the link of a full breakdown.
