Having some fun with EM measurements today - side-channels are awesome!

Wow that looks way better than what i had, did you have any usable snr with it? I tried cpa/dpa here with some near-field probes but no luck.

TBD :) Was more playing around with the sensitivity of the scope and didn't expect to see it THIS clearly

What’s the probe you’re using here? Did you just get a coil and attach it to an sma connector?

Just a coil - experimenting with some different setups

Can you reverse engineer one of these power meters? i'm sure they have tons of vulnerabilities

Can you see any signal when you do uncached writes to memory ?
