      Hello, tell please. What model of oscilloscope was used?

          Forgot to mention the easiest fix: stick a supercap on the board. No power difference means no power shenanigans. And if you are really daring, use a transistor to cut off the battery while doing sensitive operations.

            did anyone ever test this method?

            Yeah this should be the first solution, even no need for the supercap. A regular capacitor is enough for this. High freq drops will supplied by capacitor. So it can't be read on power source.

            That's what I was thinking as well, wouldn't better decoupling on the MCU minimize the effects seen on the 9V battery and be a good starting point to defend against such attacks too?

          This is old news....EEVblog #762 on youtube, not sure if its the same types as in this video but its likely to work on quite a few brands/designs.
