Vot.Ar: una mala eleccion Iván Ariel Barrera Oro & Javier Smaldone ekoparty security conference #eko11 (2015)
When the Bs As city's gov decided to implement Vot.Ar as new voting system, which is an electronic voting system passed by decree, we thought that something was wrong: especially since that system uses RFID for the ballots. So we put our hands to the business, hacked the system, and proved that it was vulnerable to several attacks like bypassing login screens, remotely destroying ballots and adding several votes with a single specially crafted ballot. Also other subjects such as the inner working of the system will be presented. The system was opened to all of the vulns during the elections, despite our warnings. A full report in spanish can be found here: http://ivan.barreraoro.com.ar/vot-ar-... (english translation in progress). Also, a short english description of the multivote attack PoC can be found here: http://ivan.barreraoro.com.ar/vot-ar-...
