Individuals who receive notification regarding this breach should take proactive steps to protect themselves. It is recommended to regularly monitor bank and credit card statements for any suspicious activity. Obtaining free copies of credit reports from the major credit bureaus and reviewing them for inaccuracies is also advised. Additionally, affected individuals might consider placing fraud alerts or credit freezes on their credit files to prevent unauthorized access.

This filing with the Vermont Attorney General serves as an official record of the incident and underscores the importance of robust data security measures for companies managing extensive personal data. The notification highlights the need for continued vigilance by those whose information was impacted.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Guard against tax fraud
File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Stay alert to targeted scams
Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.
Keep your notification letter
Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
