The astonishing revelation was published in Carbon Black’s latest quarterly report in late October.
Carbon Black researchers found “20 different state voter databases were available for purchase on the dark web”, the report reads.
Several of these databases are located in crucial swing states, including Nevada and Florida.
Those responsible for the leak, according to Carbon Black, have enlisted online records of a total of 81,534,624 voters, including their IDs, names, addresses, phone number and citizenship status.

The report said: “Critical information in these offerings included voter IDs, full names, current and previous addresses, genders, phone numbers and citizenship status, among other information.”
By acquiring these pieces of information, hackers and people interested in rigging the elections could heavily influence voters.
The report added: “Entities wishing to influence voters can use this type of information to send targeted election-related campaign materials to their desired audience, among other influential activities.”
Tom Kellerman, Carbon Black’s chief cybersecurity officer said the cyber attackers are not “just committing simple burglary or even home invasion, they’re arsonists.”

The rising possibility of a cyber attack is also lowering the trust US voters have in government institutions and democracy, with many confessing they are reconsidering heading to the polling station on Tuesday November 6, Carbon Black said.
As many as one out of four people surveyed by the researcher said they may stay home on midterm election day.
One of the 37 incident response professionals interviewed by Carbon Black’s researchers said: “They’re doing hack and leak campaigns, targeting media providers, political parties, voter databases, they’re using social media…all to build narratives that disenfranchise potential voters and damage the reputations of democracy without having to do direct interactions, which can be riskier.”
While politically motivated cyberattacks are nothing new, “what’s new, and dangerous,” the professional continued, “is the propaganda element.”
The report said: “It’s not just about directly targeting, say, voting machines, though that is certainly one viable option.
“Rather, attackers are looking to political propaganda operations, such as Russia’s 2016 hack of the Democratic National Committee.”
Next week US voters will choose one-third of the Senate seats and all 435 seats in the House of Representatives.
Donald Trump’s Republican party could soon lose the majority it holds in the House, as latest polls show Democrats hold a good chance of reclaiming the majority there.
According to polling site FiveThirtyEight, which takes polls from various platforms and combines them to provide the most ‘probabilistic’ estimate, current surveys show the Democrats have an 85.3 percent chance of winning it back.
Regaining majority also in the Senate looks less plausible, with polls stating Democrats have only 15.0 percent chance of winning.
