Beacon Mutual Data BreachExposes Social Security Numbers

The Beacon Mutual Insurance Company, a workers' compensation insurance provider headquartered in Warwick, R.I., disclosed a data breach involving unauthorized access to its computer network earlier this year.

So far, 607 Maine residents were identified as affected. The company began notifying affected consumers by written letter on May 18, 2026.

An unauthorized person gained access to some of the company's systems between Jan. 7 and Jan. 14, 2026, allowing them to make copies of certain files stored on the network. The company detected the unauthorized activity on Jan. 14, 2026.

Shortly after the intrusion, on Jan. 31, 2026, a ransomware group known as INC RANSOM posted a claim on the dark web's Tor network stating it had obtained 275 gigabytes of the company's data. The group claimed the compromised data included internal corporate documents and correspondence, complete financial statements and reports spanning 2018 through 2025, a full employee list with personal details, and confidential agreements, NDAs, vendor contracts and partnership documents.

The types of personally identifiable information exposed in the breach included names, Social Security numbers and driver's license numbers.

The Beacon Mutual Insurance Company's response to the breach

To enroll, affected individuals should visit the Experian IdentityWorks website and use the activation code included in their notification letter. Enrollment must be completed by Aug. 31, 2026, as the activation code will not work after that date.

Steps to take if your information was exposed

• Place a credit freeze with all three credit bureaus. Contact Equifax (1-888-378-4329), Experian (1-888-397-3742) and TransUnion (1-800-916-8800) to help prevent anyone from opening new accounts using a stolen Social Security number.
• Request free credit reports at AnnualCreditReport.com and review them carefully for any accounts or inquiries that look unfamiliar.
• Consider placing a fraud alert on credit files by contacting any one of the three nationwide credit bureaus, which will notify the other two.
• Contact your state's DMV about the exposure of driver's license information, as some states can flag an account or issue a replacement to help prevent misuse.
• Review bank and financial account statements regularly for any unauthorized transactions or suspicious activity.
• Watch for phishing attempts that reference The Beacon Mutual Insurance Company or this breach by name, as scammers sometimes use real breach notifications to trick people into sharing more personal details.
