DHS warns of vulnerabilities in American voting machines; All use China-made components

Amid growing concern over Chinese-made parts in American voting machines, the Department of Homeland Security (DHS) said it will deny grants to states that do not conduct post-election audits.

DHS Secretary Markwayne Mullin, in a letter to the White House Transparency Task Force released on Thursday, detailed how American voting machines which use China-made components could be exploited by hackers or other malicious actors.

Nine voting system vendors are used for U.S. elections. Mullin wrote that three of those vendors, ES&S, Hart InterCivic, and Dominion, make up more than 80% of the market share. Each has acknowledged that its voting machines are manufactured with parts made in China.

“Voting machines with components manufactured by foreign adversaries introduce significant security risks,” Mullin wrote. “These vulnerabilities mean that malicious actors could potentially compromise election infrastructure at any stage of the supply chain, even before the machines are assembled or deployed.”

Mullin continued: “If a component is tampered with during manufacturing, it could serve as a point-of-entry for hackers, allowing for the possibility of synchronized attacks across multiple machines and jurisdictions.”

“Unfortunately, the voting-system industry, like other sectors of critical infrastructure, is impacted by the fact that some necessary components cannot be sourced from domestic manufacturers, so vendors are dependent on foreign suppliers,” Mullin noted.

“The Homeland Security Grant Program requires states to trust but verify the results produced by the voting machines,” Mullin wrote. “To receive full grant awards, states must demonstrate that they have conducted random post-election manual counts of paper ballots to ensure that any errors or manipulation are detected. This is in addition to numerous other actions being taken across DHS components to secure election infrastructure.”

Earlier this year, the Trump Administration moved to ban the import of all internet routers manufactured in foreign countries because of the security risks posed by Chinese hacking capabilities.
