TX: Denton County Discovers COVID-19 Application Leaked Data of 346,000 Individuals
Denton County in Texas has discovered a vulnerability in a third-party provider application used in connection with individuals’ personal health information has potentially been exploited by unauthorized individuals. The application was used at COVID-19 vaccination clinics in the County, and contained information such as names, dates of birth, email addresses, phone numbers, and COVID-19 vaccination information. The vulnerability, discovered by Denton County officials on July 7, 2021, meant the information in the application database was accessible by anonymous users. When the flaw was discovered, the application was immediately shut down and an investigation was launched to determine the extent of the issue and whether any unauthorized individuals had exploited the flaw to gain access to sensitive data. Denton County confirmed that an error had been made configuring the application which exposed data to unauthorized individuals. While no evidence was found to indicate any actual or attempted misuse of individuals’ protected health information, it was not possible to rule out...
NCCoE Releases Final Cybersecurity Practice Guide on Mobile Application Single Sign-On for First Responders
The National Cybersecurity Center of Excellence (NCCoE) at the National Institute of Standards and Technology (NIST) has recently released the final version of the NIST Cybersecurity Practice Guide SP 1800-13, Mobile Application Single Sign-On: Improving Authentication for Public Safety First Responders. Public safety and first responder (PSFR) personnel require on-demand access to public safety data in order to provide proper support and emergency care. In order to access the necessary data, PSFR personnel are heavily reliant on mobile platforms. Through these platforms, PSFR personnel can access the personal and protected health information of patients and sensitive law enforcement information; however, in order to keep sensitive information secure and to prevent unauthorized access, strong authentication mechanisms are required. Those authentication mechanisms are needed to keep data secure and to protect privacy, but they have the potential to hinder PSFR personnel and get in the way of them providing emergency services. While authentication may only take a matter of seconds,...
Data Breaches at Business Associates Affect LifeLong Medical Care & Beaumont Health Patients
LifeLong Medical Care, a Californian healthcare provider serving patients in Alameda, Contra Costa, and Marin Counties, has notified certain patients whose protected health information was impacted in a ransomware attack on the third-party vendor Netgain Technologies. The breach has been reported to the HHS’ Office for Civil Rights as involving the PHI of 115,448 patients. Netgain Technologies discovered a security breach on November 24, 2020 involving ransomware. An internal investigation into the breach determined on February 25, 2021 that the attackers had accessed and obtained files containing the information of its customers. The attackers first breached its systems on November 15, 2020. LifeLong Medical Care said it launched a comprehensive investigation into the breach and discovered on August 9, 2021 that the personal and protected health information of patients was accessed and/or exfiltrated from Netgain’s network. Affected patients had their full name compromised along with one or more of the following data elements: Social Security number, date of birth, patient...
CISA Updates List of Cybersecurity Bad Practices to Eradicate
The Cybersecurity and Infrastructure Security Agency (CISA) has updated its list of cybersecurity bad practices that must be eradicated. Cyber threat actors often conduct highly sophisticated attacks to gain access to internal networks and sensitive data, but oftentimes sophisticated tactics, techniques and procedures are not required. The Bad Practices Catalog was created in July 2021 to raise awareness of some of the most egregious errors that are made in cybersecurity that leave the door wide open to hackers. There have been many lists published on cybersecurity best practices to follow, and while it is vital that those practices are followed, it is critical that these bad practices are eradicated, especially at organizations that support critical infrastructure or national critical functions (NCFs). These bad practices significantly increase risk to the critical infrastructure relied upon for national security, economic stability, and life, health, and safety of the public. When the Bad Practices Catalog was first published, two entries were added. First on the list is the...
CareATC Email Accounts Accessed by Unauthorized Individuals
CareATC, a Tulsa, OK-based population health management company, has discovered the email accounts of two employees have been accessed by unauthorized individuals, who potentially gained access to the personal information of patients and employees. CareATC launched an investigation on June 29, 2021 when suspicious activity was detected in the email account of an employee. Third-party forensics specialists were engaged to assist with the investigation and determine the extent and scope of the security breach. That investigation revealed a second email account had also been compromised, with the two email accounts subject to unauthorized access between June 18 and June 29, 2021. Upon discovery of the compromised email accounts steps were taken to block any further unauthorized access, and a comprehensive review was conducted to determine which patient data had been exposed. The review was completed around August 11, 2021. For the majority of affected individuals – which include patients, employees, and dependents of patients and employees – the information in the compromised email...
