( CNN) According to allegations released last week by Special Counsel Robert Mueller, Russian intelligence officers successfully violated voter registration databases during the course of its 2016 election. This echoes the Senate Intelligence Committee’s finds in a preliminary report on Russian interference in the election, which stated that Russia was “in a position to, at a minimum, alter or delete voter registration data” for a small number of states. The reality that a hostile foreign dominance had this capability is chilling, as voter registration databases may be our election system’s greatest vulnerability.

Last month’s California primary elections included a troubling incident at Los Angeles referendums, where a printing lapse was instrumental in over 118,000 voters being left off registration rollers. This misunderstanding is sufficient to induce distraction and imperil individuals’ ability to gave a referendum — the actual number of people who simply opted not to vote when told they were not on the rollers is hopeless to forecast. What if, on the eve of this November’s election, a government was found that a cyberattack has removed millions of voters from its rollings?

A cyberattack on registration rosters have had the opportunity to hugely injure the integrity of democratic elections in two definite access. First, a targeted removal of a blocking of many thousands of voters likely to support one candidate could effectively fluctuating a close election. Second, a broad-spectrum assault that purifies an entire state’s registration database are likely to endanger the capabilities needed of an election to functionally started. Both scenarios threaten to do permanent damage to the integrity of and trust in our electoral system.
