State voter registration systems can be vulnerable to voter and election fraud, though the extent of this vulnerability can vary depending on the specific design and its security measures. Potential vulnerabilities can include weak passwords, outdated software, and a lack of proper encryption, among other factors.
Examples of past cyber attacks on state voter registration systems include the 2016 attack on Illinois' voter registration database, which resulted in the theft of personal information belonging to up to 200,000 voters. In 2017, the Department of Homeland Security notified multiple states that hackers had targeted their registration systems before the 2016 election.
However, it is essential to note that instances of voter fraud through tampering with state voter registration systems are relatively rare compared to other forms,
such as illegal voting or voter impersonation.
Additionally, many states have improved cybersecurity measures and safeguarded their voter registration databases.
To protect against voter fraud in state voter registration systems, states can upgrade their cybersecurity protocols, including measures like two-factor authentication and regular monitoring of voter registration databases.
It's also essential to provide adequate training for election officials to ensure they are aware of and can identify potential weaknesses in the system. Regular audits and reviews of voter registration databases can also help identify and correct vulnerabilities.
