What do Apple, the FBI and a Belgian politician have in common? In 2003, inBelgium there was an election using electronic voting machines. Mysteriouslyone candidate summed an excess of 4096 votes. An accurate analysis led to theofficial explanation that a spontaneous creation of a bit in position 13 of thememory of the computer attributed 4096 extra votes to one candidate. One of themost credited answers to this event is attributed to cosmic rays i.e.(gamma),which can filter through the atmosphere. There are cases though, with classicalcomputers, like forensic investigations, or system recovery where suchsoft-errors may be helpful to gain root privileges and recover data. In thispaper we show preliminary results of using radioactive sources as a mean togenerate bit-flips and exploit classical electronic computation devices. Weused low radioactive emissions generated by Cobalt and Cesium and obtainedbit-flips which made the program under attack crash. We also provide the firstoverview of the consequences of SEUs in quantum computers which are today usedin production for protein folding optimization, showing potential impactfulconsequences. To the best of our knowledge we are the first to leverage SEUsfor exploitation purposes which could be of great impact on classical andquantum computers.
