391,472 Patients Impacted by Sarrell Dental Ransomware Attack
Sarrell Dental, an Alabama-based not-for-profit provider of children’s dental and optical services, has experienced a ransomware attack in which the protected health information of its patients may have been compromised. Sarrell Dental is the largest provider of dental services in the state of Alabama and operates 17 clinics in the state. In July 2019, ransomware was deployed on its network which resulted in widespread file encryption. Upon discovery of the attack, the network was deactivated, and an investigation was launched. Affected clinics were closed for two weeks while the breach was investigated and systems were restored. A ransom demand was received but it was not paid. Patient information was restored from backups. A third-party computer forensics team was engaged to assist with the investigation to determine the extent of the breach. That investigation revealed that the attackers may have first gained access to Sarrell Dental systems as early as January 2019. No evidence was found to suggest patient information was accessed or copied by the attackers, but the...
PHI Potentially Compromised in Cybersecurity Breach at North Florida OB-GYN
Jacksonville, FL-based North Florida OB-GYN has discovered hackers gained access to certain parts of its computer system containing patients’ personal and health information and deployed a virus that caused widespread file encryption. Upon discovery of the breach on July 27, 2019, networked computer systems were shut down and breach response and recovery procedures were initiated. Third party IT consultants assisted with the investigation and confirmed that parts of its networked computer systems had been subjected to unauthorized access and a virus had been used to encrypted certain files. The investigation revealed its systems had most likely been compromised on or before April 29, 2019. While system access was confirmed, no evidence of unauthorized data access or theft of personal or medical information was found; however, unauthorized data access and data exfiltration could not be ruled out. Protected health information potentially compromised in the attack varied from patient to patient and may have include name, demographic information, birth date, driver’s license number, ID...
Wood Ranch Medical Announces Permanent Closure Due to Ransomware Attack
Another healthcare provider has announced it will be permanently closing its doors as a direct result of a ransomware attack. The devastating attack occurred at Wood Ranch Medical in Simi Valley, CA, which recently announced that the practice will permanently close on December 17, 2019. The attack occurred on August 10, 2019 and resulted in its servers being infected with ransomware. The attack caused widespread file encryption and prevented medical records from being accessed. The extent of the attack was such that computer systems were permanently damaged making file recovery impossible. The practice had created backups of patient records, but those backups were also encrypted and could not be used to restore patient data. Ransomware attacks are usually conducted with the sole purpose of extorting money. Files are encrypted and a ransom demand is issued. If the ransom is not paid, files remain permanently encrypted. Payment of the ransom comes with no guarantee that file recovery will be possible and encourages further attacks. For these reasons the FBI recommends ransom payments...
Sen. Rand Paul Introduces National Patient Identifier Repeal Act
Sen. Rand Paul, M.D., (R-Kentucky) has introduced a new bill that attempts to have the national patient identifier provision of HIPAA permanently removed due to privacy concerns over the implementation of such a system. Today, HIPAA is best known for its healthcare data privacy and security regulations, but the national patient identifier system was proposed in the original HIPAA legislation of 1996 as a measure to facilitate data sharing and help reduce wastage in healthcare. The provision called for the HHS to “adopt standards providing for a standard unique health identifier for each individual, employer, health plan, and healthcare provider for use in the health care system.” However, in 1998, former Congressman Ron Paul (R-Texas), Sen. Rand Paul’s father, introduced a proposal which called for a ban on funding the development and implementation of such a system. The ban was introduced into the Congressional budget for 1999 and has been written into all Congressional budgets ever since. This year there was hope that the ban would finally be removed following a June amendment to...
Senator Demands Answers Over Exposure of Medical Images in Unsecured PACS
Sen. Mark Warner (D-Virginia) has written to TridentUSA Health Services demanding answers about a breach of sensitive medical images at one of its affiliates, MobileXUSA. Sen. Warner is the co-founder of the Senate Cybersecurity Caucus, which was set up as bipartisan educational resource to help the Senate engage more effectively on cybersecurity policy issues. As part of the SCC’s efforts to improve cybersecurity in healthcare, in June Sen. Warner asked NIST to develop a secure file sharing framework and wrote to healthcare stakeholder groups in February requesting they share best practices and the methods they used to reduce cybersecurity risk and improve healthcare data security. The latest letter was sent a few days after ProPublica published a report of an investigation into unsecured Picture Archiving and Communications Systems (PACS). PACS are used by hospitals and other healthcare organizations for viewing, storing, processing, and transmitting medical images such as MRIs, CT scans, and X-Rays. The report revealed more than 303 medical images of approximately 5 million...
