Security Weaknesses Discovered in New Mexico and North Carolina Medicaid Programs
The Department of Health and Human Services’ Office of Inspector General has conducted reviews of the Medicaid programs run by North Carolina and New Mexico and has identified information security weaknesses that could potentially be exploited by cybercriminals to gain access to systems and the sensitive data of Medicaid recipients. If the vulnerabilities were exploited, it would have placed the states’ Human Services Departments (HSD) at risk and compromised the confidentiality, integrity, and availability of eligibility systems. Similar reviews have been conducted to assess the security controls in place in other states. Vulnerabilities were also detected in the systems used in Colorado, Massachusetts, South Carolina and Virginia, suggesting many states are struggling to implement appropriate policies, procedures and technology to comply with federal regulations on information security. As with healthcare organizations, state Medicaid programs face budgetary constraints and a lack of resources. It can be a major challenge to ensure appropriate resources are directed to...
34,000 Impacted by Ransomware Attack at St. Mark’s Surgical Center
Another healthcare organization has been attacked with ransomware, resulting in the protected health information of almost 34,000 patients being encrypted and made inaccessible. St. Mark’s Surgical Center in Fort Myers, FL experienced the ransomware attack on April 13, 2017, which prevented patient data from being accessed until April 17, 2017. The ransomware was installed on the center’s server which contained patient’s names, dates of birth, Social Security numbers and treatment information. An investigation into the breach was immediately conducted to determine the extent of the attack and to find out which data had been encrypted and the number of patients impacted. That investigation revealed the protected health information of 33,877 patients was potentially accessed by the attackers. A third-party cybersecurity firm was called in to assist with the removal of the ransomware and to conduct a thorough forensic investigation. The firm was able to confirm that all traces of the malware were removed and further access to the server was blocked. The firm also investigated whether...
NIST Updates Digital Identity Guidelines and Tweaks Password Advice
The National Institute of Standards and Technology (NIST) has updated its Digital Identity Guidelines (NIST Special Publication 800-63B), which includes revisions to its advice on the creation and storage of passwords, on which HHS Password guidance is based. Digital authentication helps to ensure only authorized individuals can gain access to resources and sensitive data. NIST says, “authentication provides reasonable risk-based assurances that the subject accessing the service today is the same as the one who accessed the service previously.” The Digital Identity Guidelines include a number of recommendations that can be adopted to improve the digital authentication of subjects to systems over a network. The guidelines are not specific to the healthcare industry, although the recommendations can be adopted by healthcare organizations to improve password security. To improve the authentication process and make it harder for hackers to defeat the authentication process, NIST recommends the use of multi-factor authentication. For example, the use of a password along with a...
Phillips Ships DoseWise Portal with Serious Vulnerabilities
The Phillips web-based radiation monitoring app – DoseWise Portal (DWP) – has been shipped with serious vulnerabilities that could be easily exploited by hackers to gain access to patients’ protected health information. ISC-CERT has warned healthcare providers the vulnerabilities could be remotely exploited by hackers with a low level of skill to gain access to medical data. Two vulnerabilities have been identified. The first (CVE-2017-9656) is the use of hard-coded credentials in a back-end database with high privileges that could jeopardize the confidentiality, integrity and availability of stored data and the database itself. In order for an attacker to exploit the vulnerability, elevated privileges would be required to gain access to the system files of the back-office database. Even so, ICS-CERT says an attacker with a low level of skill could exploit the vulnerability and has given it a CVSS v3 rating of 9.1 out of 10. The second vulnerability (CVE-2017-9654) involves cleartext storage of sensitive information in back-end system files. The vulnerability has been given a CVSS...
Institute for Women’s Health Hacked: PHI Potentially Compromised
Ransomware attacks on healthcare organizations have increased, although that is far from the only malware threat. Keylogging malware can be used to obtain sensitive information such as login credentials, or in the case of the San Antonio Institute for Women’s Health (IFWH), credit and debit card information as it was entered into its system. The keylogging malware was discovered on the IFWH network on July 6, 2017, prompting a forensic investigation of its systems. That investigation revealed the malware had been installed on June 5, although it took until July 11 for the malware to be removed from the majority of its systems and a further two days for IFWH to confirm that the malware had been completely removed from all terminal servers and workstations. During the time that the malware was present, it recorded and transmitted sensitive data as information was entered into its system. The types of data recorded by the malware between June 5 and July 11 includes names, dates of birth, addresses, Social Security numbers, scheduling notes, current procedural technology and other...
