Multiple lawsuits filed against Doyon Ltd over April 2024 data breach and late notification

Posted on July 13, 2025 by Dissent

KUAC reports:

Multiple class action lawsuits recently filed in federal court claim an Interior Alaska Native Corporation failed to take reasonable steps to protect personal data from a cyberattack last year.

Court filings show at least four different plaintiffs have lodged a complaint against Doyon, Ltd., in Alaska District Court since mid-June, on behalf of themselves and “all others similarly situated.” A motion to consolidate the cases is now before Alaska District Court Judge Sharon Gleason.

Doyon is a regional Alaska Native corporation based in Fairbanks that operates companies in multiple industries, including utilities, construction and information technology, among others. The for-profit corporation’s website says Doyon has about 20,700 shareholders and employs 1,300 people nationwide.

The lawsuits all contain similar allegations, arguing that Doyon had shoddy measures in place to keep clients, employees, shareholders and their dependents sheltered from a data breach in April of last year.

That breach saw cyberattackers potentially gain access to files with sensitive personal details, like social security numbers and health information.

In June 2025, more than one year after the April 1, 2024 incident, Doyon was first notifying people affected by the incident. As of publication today, they have yet to reveal how many people, total, were affected by the incident, although they notified the Texas Attorney General’s Office in June that 906 Texans were affected. They also notified the Maine Attorney General’s Office that 22 Maine residents were affected. Vermont and California were also notified, although no numbers were provided in those notification letters.

The incident has not shown up on HHS’s public breach tool, and it is not clear whether more than 500 people had protected health information involved or not. Doyon employs 1,300 people nationwide but their dependents may also be affected if health insurance for employees was involved and/or former employees and their dependents were involved.
