What may have been exposed

  • Full Name
  • Social Security Number
  • Date of Birth
  • Mailing Address
  • Financial Account Number
  • Routing Number
  • Lease and Rental Application Details
  • Tax and Income Verification Records

MPB Property LLC, a company involved in real estate and property management within Maine, filed a data breach notification with the state's Attorney General's office on May 27, 2026. The specific type of security incident that led to the exposure of data remains unspecified in public disclosures, and the investigation into the breach is currently ongoing with a status of monitoring.

According to the official filing, the exposed data types are comprehensive and highly sensitive. These include Full Name, Social Security Number, Date of Birth, Mailing Address, Financial Account Number, Routing Number, Lease and Rental Application Details, and Tax and Income Verification Records. Such information is routinely collected by property management companies from tenants, applicants, and vendors during their operations.

The compromise of these specific categories of personal and financial information can lead to significant risks for affected individuals. Exposed Social Security Numbers and Dates of Birth are frequently used by malicious actors for identity theft, while Financial Account Numbers and Routing Numbers can directly enable unauthorized financial transactions and account takeovers. Lease and Rental Application Details, combined with other identifiers, can facilitate targeted fraud.

Individuals who receive notification regarding this breach are advised to take protective measures. It is recommended to regularly review credit reports for any unauthorized accounts or suspicious activity. Additionally, close monitoring of all financial account statements, including bank accounts, is critical to detect potential fraud. Exercising caution with unsolicited communications that request personal information is also a prudent step to mitigate further risk.

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.
