"ChipWhisperer" achieves an awesomely 'impossible' feat.
It manages to "crack" 'some' cryptographically secure systems in small time
frames without using brute force attacks.
There are ways of preventing it doing so.
Which is its reason for existing.

If you rely on cryptography for system security you may want to know.

Chip Whisperer is a security investigation device designed to probe the
security of cryptographically secure systems to side-channel and glitching
attacks. It uses "apparently impossible" means such as "listening" to noise
on power supply affected lines (including casings and external cables in
some instances) to derive long code words by analysing short segments (to
put it so simplistically as to be about meaningless.)

A major point made is that "Secure because Math" is not by itself good
enough.

Hackaday competition 2nd place  I think.
