DCH Health System Ransomware Attack Temporarily Cripples 3 Alabama Hospitals
DCH Health System has been forced to close all three of its Alabama hospitals for all but critical new patients following a ransomware attack. The attack prevented staff at DCH Regional Medical Center in Tuscaloosa, Northport Medical Center, and Fayette Medical Center from accessing computer systems, which were taken out of action as a result of the attack which commenced in the early hours of Tuesday, October 1, 2019. Emergency procedures were implemented at all three hospitals to ensure day to day healthcare operations could continue and care is continuing to be provided to patients currently at the hospital. Critical patients are being accepted, but individuals scheduled for outpatient procedures or tests have been advised to call before attending. Ambulance services have been advised to take patients to alternate facilities if possible. The health system started using backup files to restore certain system components which allowed those systems to be brought back online. DCH Health System also purchased the decryption keys from the attacker. “We worked with law enforcement and...
URGENT/11 Cybersecurity Vulnerabilities in Medical Devices Prompt FDA Warning
Security researchers at Armis have identified 11 vulnerabilities in the Interpeak IPnet TCP/IP Stack, a third-party software component used in hospital networks and certain medical devices. The vulnerabilities were reported to the DHS Cybersecurity and Infrastructure Security Agency (CISA) prompting an ICS Medical Advisory and a Food and Drug Administration (FDA) Safety Communication warning patients, healthcare providers, facility staff and manufacturers about the flaws. The FDA alert – named URGENT/11 – explains that the vulnerabilities could be remotely exploited by a threat actor allowing full control to be taken of a vulnerable medical device. An attacker could change the functions of the device, access sensitive information, cause logical flaws or denial of service attack that could stop the device from working. While there have been no reports of the flaws being exploited in the wild, the FDA warns that the software required to exploit the flaws is publicly available. Interpeak IPnet TCP/IP Stack supports network communications between computers, and while it is no longer...
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...
