26-Month Malware Infection of Tillamook Chiropractic Clinic Discovered

Oregon-based Tillamook Chiropractic Clinic’s system was discovered to have been infected by malware, resulting in the theft of the health information of 4,058 patients. The clinic became aware of the malware on its system on August 3, 2018 during an internal security audit. The malware was installed despite having a firewall, anti-virus and anti-malware software installed and its computers and servers being fully patched.

Upon investigation of the security breach, it was found that the malware was installed on its insurance billing system on May 24, 2016. The attackers used the system as a staging area for collecting patient data before exfiltration. For 26 months this security breach was not detected.

The stolen information includes full names, home and work addresses, birth dates, telephone numbers, diagnoses, laboratory test results, prescribed medicines, driver’s license numbers, insurance billing data, bank account numbers, bank routing numbers, employee payroll details, and Social Security numbers of Medicare patients.

Tillamook Chiropractic Clinic eliminated the malware  on August 3, 2018 and upgraded its network security systems to prevent further malware infections.
