Careful with EVM Indian EVMs consist of a ballot unit used by voters and a control unit operated by poll workers. The control unit displays vote totals for each candidate at the end of the election. The ballot unit is used by voters, who simply press the button corresponding to the candidate of their choice. Inside the EVM is a main circuit board with the CPU and vote memory, as well as a smaller display board. This hardware has never before been subjected to detailed public scrutiny. Demonstrate how criminals could replace the display in the EVM with a dishonest look-alike, shown here. We added parts, hidden under the LEDs, that substitute dishonest vote totals when showing election results. an application that runs on an Android mobile phone and wirelessly tells the dishonest display which candidate should receive the stolen votes. US developed a demonstration attack device that clips on to the memory chips inside the EVM and steals votes. The clip-on attack device is small enough to fit in a shirt pocket.
