Mina Kim. National security officials have announced that Iran and Russia

obtained voter registration data that could be used to threaten voters and so confusion this election,

paying particular attention to Iran's activities. But cybersecurity experts, according to the New York

Times, say Russia remains the more dangerous threat to the integrity of the 2020 election.

We look at the latest foreign attempts at election interference and put into perspective the risks they pose.

We're joined by David Sanger, National Security correspondent and senior writer for the New York Times.

There's also a new HBO documentary based on Sanger's 2018 book on cyber

warfare titled The Perfect Weapon. Thanks so much for joining us, David Sanger. Great to be

with you. Thanks for having me back to KQED. So I want to begin with Iran because that's what

the director of national intelligence, John Ratcliffe, paid attention to last week, Iran's involvement in these

faked emails threatening voters. Can you talk a little bit more about what they're up to?

Well, what we saw were some emails that weren't terribly artful, written to some voters in Florida

and Alaska. There may have been elsewhere, but those were the ones

that we saw that pretended to be from the proud boys, the far, far right activist group, and basically

said to voters, we know who you are, we know that you're registered as a Democrat, we can see your

votes, which they can't.

And we're coming for you if you don't vote for Trump.

So hard to know exactly how this would play.
