‘Plundervolt’ attack breaches chip security with a shock to the system

Today’s devices have been secured against innumerable software attacks, but a new exploit called Plundervolt uses distinctly physical means to compromise a chip’s security. By fiddling with the actual amount of electricity being fed to the chip, an attacker can trick it into giving up its innermost secrets. It should be noted at the outset that while this is not a flaw on the scale of Meltdown or Spectre, it is a powerful and unique one and may lead to changes in how chips are designed. There are two important…

Bob Clagett made an LED Christmas tree video game for his entire town to play

Bob Clagett likes making holiday decorations. This year, however, he wanted to create something that didn’t just look nice, but was also interactive. What he came up with is a giant Christmas tree that is actually a video game! His tree-shaped matrix uses seven rows of RGB LEDs attached to the top of the structure to drop simulated snowflakes, represented by white lights. The player moves a dot on the bottom right and left to dodge these falling flakes via a pair of large arcade-style buttons. When the controlling Arduino…
