The only way they can fraud is if they steal ballots. They don't know who is registered and voted to do fake ballots. I doubt they can perfectly reproduce the paper or envelopes. Not in secret atleast on the scale they need to.
It's a very low risk. For a low reward not worth going to jail. They would have to have a major operation to scale. One guy frauding a few ballots does not change a election. I can be wrong but calling it easy fraud and that is happening is fake news. There is no evidence of any fraud is happening. Just because it theoretically can happen. Doesn't mean it is.
Yeah, there's no way anyone wishing to cause chaos in the election would be able to get anything as closely guarded as voter registration information....
FBI: Iran, Russia obtained voter data to interfere with US electionshttps://www.cnet.com/news/fbi-iran-russia-obtained-voter-data-to-interfere-with-us-elections/Then there are the "ballot harvesters" who, for one thing, go to housing areas where elderly live and either pay them for their ballots, tell them how to sign and fill them out, or just take them without paying.
And there are reports of STACKS of ballots in trash cans in apartment complexes where the common mailbox area is. Just scoop and vote ... many times.
A woman on the news said she arrived to vote at the polling place, and they would not let her because the computer said she'd already voted.
If every Republican in Hawaii that voted for Trump was able to find a way to vote just once more in the state, the total would have been 372, 838 for Trump. Biden had 355,226.
But, hey. That's just one person voting one extra time, right?
Not a smidgeon of fraud.
