Study Reveals Healthcare Employees Have Unnecessary Access to Huge Amounts of PHI
A new study has revealed widespread security failures at healthcare organizations, including poor access controls, few restrictions on access to protected health information (PHI), and poor password practices, all of which are putting sensitive data at risk. The study, conducted by the data security and insider threat detection platform provider Varonis, involved an analysis of around 3 billion files at 58 healthcare organizations, including healthcare providers, pharmaceutical companies, and biotechnology firms. The aim of the study was to determine whether security controls had been implemented to secure sensitive data and to help organizations better understand their cybersecurity vulnerabilities in the face of increasing threats. The Health Insurance Portability and Accountability Act (HIPAA) requires access to PHI to be limited to employees who need to view PHI for work purposes. When access is granted, the HIPAA minimum necessary standard applies, and only the minimum amount of PHI should be accessible. Each user must be provided with a unique username that allows access to...
International Law Enforcement Operation Takes Down REvil Ransomware Gang’s Infrastructure
In July 2021, the notorious REvil (Sodinokibi) ransomware gang appeared to have ceased operations, with both its Tor payment site and data leak blog suddenly going offline. The DarkSide ransomware operation also went quiet, leading many security experts to believe that the operators of the ransomware-as-a-service (RaaS) operations were laying low or that there had been a law enforcement takedown of their infrastructure. Some of the servers used by the REvil gang were brought back online temporarily but were shut down again in mid-October. This temporary resurrection was thought to be an affiliate attempting to continue the operation. The apparent shutdown of the REvil operation followed two major attacks on the food production company JBS and the software management company Kaseya, with the later attack affecting around 50 managed service providers and up to 1,500 downstream businesses. Associates of the REvil gang had developed the DarkSide ransomware variant, which was used in the attack on Colonial Pipeline and caused its fuel pipeline to the Eastern seaboard of the United...
PHI of 24,891 Specialty Surgery Center of Central New York Patients Potentially Compromised
Syracuse ASC, dba Specialty Surgery Center of Central New York, has started notifying 24,891 patients that some of their protected health information (PHI) was potentially accessed by unauthorized individuals who gained access to its computer systems. The breach was identified by Syracuse ASC around March 31, 2021, and steps were immediately taken to secure its systems and prevent further unauthorized access. A third-party cybersecurity firm was engaged to assist with the forensic investigation, which concluded on April 30, 2021, and determined the hackers accessed parts of its systems that contained PHI. A second investigation was conducted to determine which individuals’ PHI had been exposed. A list of individuals potentially affected by the incident was obtained on August 16, 2021, with the delay in issuing notifications due to a “substantial data validation process to verify the accuracy of the data.” The file review confirmed names may have been compromised along with limited health information, but no evidence was found to indicate any actual or attempted misuse of data on...
Cybersecurity Awareness Month: Put Cybersecurity First
The theme of the fourth week of Cybersecurity Awareness Month is “Cybersecurity First”, with the focus on getting the message across to businesses about the need for cybersecurity measures to address vulnerabilities in products, processes, and people. Cybersecurity Advice for Companies One study suggests 64% of companies worldwide have experienced some form of cyberattack and the rate at which attacks are occurring is increasing. It is essential for companies to ensure that cybersecurity measures are incorporated when developing apps, products, or new services and for cybersecurity to be considered at the design stage. Safeguards need to be baked into products from the start. Cybersecurity should not be an afterthought. Businesses need to have a thorough understanding of their IT environment and what assets need to be protected. An inventory should be created for all assets and the location of all sensitive data should be known. A plan then needs to be developed to protect those assets, which should include overlapping layers of protection using technologies such as firewalls, spam...
44% of Healthcare Organizations Don’t Have Full Visibility into 3rd Party Access and Permissions
A recent study conducted by the Ponemon Institute on behalf of cybersecurity firm SecureLink has explored the state of third-party security and critical access management at healthcare organizations. As with other industry sectors, remote access to internal systems is provided to third parties to allow them to perform essential business functions. Whenever a third party is provided with access, there is a risk that access rights will be abused. Credentials could also potentially be obtained by cyber threat actors and used for malicious purposes. While healthcare organizations are aware that providing access to third parties involves a degree of risk, in healthcare the level of risk is often underestimated. The healthcare industry is extensively targeted by cyber actors and the industry experiences four times the number of data breaches as other industry sectors and the threat is growing. A recent Bitglass study suggests a 55% increase in healthcare data breaches in the United States during the pandemic. SecureLink’s study, the results of which were published in the report, A Matter...
