Mojave Research: 12 Vulnerabilities in Dominion Voting Systems, No Exploitation Evidence
This digest was compiled by AI from multiple sources — links to the originals are below.
Mojave Research found at least a dozen high- or critical-severity software vulnerabilities in Dominion voting systems used in Puerto Rico’s 2024 elections, but no evidence any were exploited. The Trump administration shut down the firm’s election-security work after its findings did not support claims of manipulation. The shutdown followed federal requests to expand the team from about 10 to 60 people.
Key Facts
- Mojave Research spent roughly six weeks analyzing Dominion voting systems used in Puerto Rico’s 2024 elections and found at least a dozen high- or critical-severity software vulnerabilities.
- The company found no evidence that any of the weaknesses had been exploited or that votes had been changed.
- Federal officials asked Mojave to grow the team working on the effort from roughly 10 people to about 60.
- The work was abruptly shut down after Mojave's findings did not support claims of election manipulation.
- ODNI under then-director Tulsi Gabbard asked Mojave last year to travel to Puerto Rico and capture an image of a voting system used in an election without vendor oversight.
Dominion Voting Vulnerabilities
Mojave Research found at least a dozen high- or critical-severity software vulnerabilities in Dominion voting systems used in Puerto Rico's 2024 elections. Passwords were reused, firewalls were disabled, and basic cryptographic protections were poorly implemented. Active cellular hardware modems in Puerto Rico opened additional pathways into underlying software that was thought to be isolated. The firm found no evidence that any of the weaknesses had been exploited or that votes had been changed, but wanted more time to be certain.
Shutdown and Political Pressure
Federal officials initially asked Mojave Research to grow the team from roughly 10 people to about 60. Mojave received an authorization to proceed, hired personnel, and was given funding to acquire equipment for examining more voting systems ahead of the November midterms. A contracting officer had been brought in to finalize the new agreement. The work was abruptly shut down as Mojave prepared to move ahead. Wareham and Gulati recounted the episode on Friday at DEF CON hacker convention's Voting Village, where they unpacked their technical findings.
ODNI Probe Origins
Mojave's involvement began last year through the Office of the Director of National Intelligence under then-director Tulsi Gabbard. ODNI asked Mojave to travel to Puerto Rico and capture an image of a voting system that had actually been used in an election without the vendor overseeing the process. Reuters reported in February that the May 2025 operation was tied to an effort involving ODNI and the FBI to investigate allegations that Venezuela had hacked Puerto Rico's voting systems. Gabbard's office denied that Venezuela drove its work and said the examination was focused on technical vulnerabilities. The probe produced no clear evidence of Venezuelan interference.
