The cyber expert on the “red team” hired by MyPillow CEO Mike Lindell now says the key data underpinning the theory that China hacked the 2020 election unveiled at the Cyber Symposium is illegitimate. Mr. Lindell said he had 37 terabytes of “irrefutable” evidence that hackers, who he said were backed by China, broke into election systems and switched votes in favor of President Biden. The proof, he said, is visible in intercepted network data or “packet captures” that were collected by hackers and could be unencrypted to reveal that a cyberattack occurred and that votes were switched.
