BELLINGHAM, WA (MyBellinghamNow.com) – A Whatcom County medical center has responded to a cyberattack involving personal information from hundreds of thousands of state residents.

Mt. Baker Imaging (MBI) posted a notice on its website on Oct. 30 giving more details into the data breach that occurred roughly nine months earlier. The company also sent out letters with similar information to patients that were believed to have been affected by the breach.

My Bellingham Now previously reported that Mt. Baker Imaging and Northwest Radiologists were hit by a cyberattack in late January.

MBI says the affected data included patients’ first and last names, social security numbers, driver’s license numbers, treatment and diagnosis information, and more.

It adds that it has no evidence that the compromised information was used maliciously, but has still added extra security measures to prevent it from happening again.

According to a filing with the state Attorney General’s Office, over 348,000 Washington residents were impacted by the breach.

Two Whatcom County residents later sued the two companies, claiming they didn’t do enough to inform patients about the incident.

Mt. Baker Imaging has set up a dedicated call center to answer questions and address concerns about the data breach. The number for the dedicated call center is 1-855-291-2706. You can also send concerns or questions via mail to 2930 Squalicum Parkway, Suite 101, Bellingham, WA 98225.
