Nashville, Ark.-based Howard Memorial Hospital reported hackers may have stolen files from its network during a cyberattack earlier this year.
Howard Memorial discovered suspicious activity on its computer network Dec. 4 and an unknown actor alleged they stole data from the hospital's network, according to a Dec. 29 news release.
"Steps were promptly taken to secure HMH's network, and an investigation began with assistance from outside cybersecurity specialists to determine the nature and scope of this activity and to safely maintain full operational functionality so HMH could continue to treat patients," according to the news release.
The ongoing investigation found an unknown actor had access to the hospital's network from Nov. 14 to Dec. 4, and may have stolen certain files. The hospital is still reviewing the at-risk files to identify affected patients and employees.
Data potentially breached during the incident includes names, contact information, birth dates, Social Security numbers. Employees may also have had their direct deposit bank account information breached.
