CommonSpirit Health Says EHRs Mostly Back Online Following Ransomware Attack
CommonSpirit Health has recently provided an update on the progress that has been made in recovering from an October 2022 ransomware attack that affected many facilities across its network. The attack was detected on October 3, which forced the health system to take its IT systems offline, including its MyChart electronic health records (EHRs). CommonSpirit Health, Catholic Health Initiatives (CHI Health), MercyOne, and St. Luke’s Health facilities were affected and have been operating under emergency procedures since the attack. CommonSpirit Health had previously stated that there was no impact on patient care and associated systems at Dignity Health, TriHealth, and Centura Health. It has now been more than a month since the attack and business operations have yet to return to normal; however, CommonSpirit Health has recently confirmed that the majority of impacted locations now have access to their EHR systems again and patients of those facilities should now be able to access patient portals to view their medical records. Appointment scheduling systems are still affected, so...
HC3 Sounds Alarm About Venus Ransomware
The Health Sector Cybersecurity Coordination Center (HC3) has recently shared details of the tactics, techniques, and procedures associated with Venus ransomware attacks, and has made several recommendations on mitigations that healthcare organizations can implement to improve their defenses against attacks. Venus ransomware, aka GOODGAME, is a relatively new threat, having first been identified in mid-August 2022; however, the ransomware has been used globally in attacks and there are now submissions of the ransomware variant every day. While the threat group is not known to specifically target the healthcare sector, there has been at least one attack on the healthcare industry in the United States. The primary method of initial access, as is the case with several ransomware groups, is exploiting publicly exposed Remote Desktop services to encrypt Windows devices, including Remote Desktop on standard and non-standard TCP ports. Once access has been gained, the ransomware will attempt to terminate 39 processes associated with database servers and Microsoft Office applications....
The Riskiest Connected Devices in Healthcare
The number of connected devices being used in hospitals continues to grow and while these devices can improve efficiency, safety, and patient outcomes, they have also substantially increased the attack surface, and many of these devices either lack appropriate security features or are not correctly configured. According to a recent Microsoft-sponsored study by the Ponemon Institute into the current state of IoT/OT cybersecurity, 65% of organizations said their IoT/OT devices were one of the least secured parts of their networks, with 50% reporting an increase in attacks on IoT/OT devices. 88% of respondents said they have IoT devices that are accessible over the Internet, and 51% have OT devices accessible over the Internet. Cybercriminals are increasingly attacking these devices as they are a weak point that can be easily exploited. These devices are the target of malware, ransomware, and are among the main initial access points for malicious actors. In 2020, Forescout analyzed the types of devices used in enterprise networks to determine which pose the highest risk, and this...
Lurie Children’s Hospital Proposes Settlement to End Insider Breach Lawsuit
Ann & Robert H. Lurie Children’s Hospital has proposed a settlement to resolve a class action lawsuit filed in response to two privacy breaches involving unauthorized medical record access by employees. On November 15, 2019, the Chicago hospital discovered an employee had been impermissibly accessing patient records. The investigation determined the unauthorized access occurred between Sept. 10, 2018, and Sept. 22, 2019. The employee, a nursing assistant, viewed patient records that included names, addresses, dates of birth, and medical information, including diagnoses, medications, appointments, and procedures. Once the unauthorized access was confirmed, the employee was terminated. Lurie Children’s Hospital notified affected patients in December 2019 and said there was no reason to suggest the information had been further discovered or misused. A similar breach was detected by the hospital in 2020. A nursing assistant was discovered to have accessed patient records without authorization between November 1, 2018, and February 29, 2020, and was also terminated. Patients were...
Security Awareness Training Does Not Appear to Improve Password Hygiene
Security awareness training is a vital part of any security strategy; however, one area where it appears to be having little effect is improving password hygiene. Employees can be taught what a strong password is and how passwords should be created, but even though the theory is understood it is not being put into practice. Employees may be made aware of the importance of practicing good cyber hygiene when it comes to passwords, but creating complex, unique passwords for every account is difficult, and remembering those passwords is almost impossible. Each year, LastPass conducts its Psychology of Passwords survey, which this year was conducted on 3,750 professionals. Respondents were probed about their password practices for their personal and work accounts. The survey revealed there was a high level of confidence in current password management practices, but in many cases, there was a false sense of safety, as good password hygiene was not always practiced. The biggest disconnect was with Gen Z, which had the highest level of confidence in their password management practices, yet...
