"The Commission had announced a similar challenge in 2009 and it claimed no one could hack its EVMs." No one can hack them, or nobody has had long enough with just "a week or 10 days". Hardware and software reverse engineering can take significantly longer, depending on the complexity of the machine. It's likely they will also be limited in what they are allowed to use. If they are so confident, open source the designs and let researchers take a look. Another reason for why their claim may be false, is the value of somebody freely giving their hack away. Sure, a moments national glory as you get a targeted painted on you for publicly embarrassing your government - or - lots of bit coin on the black market to the highest bidder. Ideas: * Simply place a piece of pink paper over the top to change the details, so the buttons no longer correlate to their correct vote. Enough people in enough provinces would make a serious difference. At the end of the day, have somebody take the paper back off before the poll closes so that the evidence of tampering is gone. * Large electro magnet to device, making all votes erased. Using statistical data from previous elections, as well as popularity polls from previous elections, predict which machines will be worth taking out to sway the vote. These devices are electronic, therefore likely to use some form of memory that is electromagnetically erasable or corruptible. * Hack the device that retrieves the data from the machines. * Social engineering, through bribery or blackmail.
