PARKERSBURG, W.Va. — One Community Federal Credit Union has reported a data breach involving names, Social Security numbers and financial account information, according to a notice posted by the Massachusetts Attorney General’s Office.
The $97-million credit union said it discovered suspicious network activity July 13. An investigation found that an unauthorized party accessed its network and may have viewed or acquired files between July 7 and July 13, 2026, the notice said.
According to its filing by the AG’s office, the credit union secured the network, contacted law enforcement and hired a forensic security firm. It determined Sept. 18 that the affected files contained personal information.
One Community said it had no evidence that the information had been misused for fraud or identity theft. It is enhancing technical security measures and offering affected individuals complimentary credit monitoring, fraud consultation and identity theft restoration services, according to the notice.
Ransomware Group Claims Responsibility
ClaimDepot reported that the ransomware group DragonForce claimed responsibility, saying it obtained more than 111 gigabytes of data and threatened to publish it on the dark web. That claim was not independently verified. The credit union’s notice does not identify an attacker or specify how much data may have been acquired.
The notice does not state the total number of people affected.
In a separate July 15 service update, One Community said an outage had affected some systems. Online and mobile banking remained available, while ATM and branch withdrawals were subject to limits.
