Feature of DICOM Image Format Could Be Abused to Fuse Malware with PHI
The DICOM image format, which has been in use for around for 30 years, contains a design ‘flaw’ that could be exploited by hackers to embed malware in image files. Were that to happen, the malware would become permanently fused with protected health information. The DICOM file format was developed to allow medical images to be easily stored and shared. It eliminated the need for physical films and solved hardware compatibility issues. DICOM is now the standard format used for MRI and CT images and is supported by most medical imaging systems. The file format can be read by a range of devices that are used to view patient image files and diagnostic information. DICOM images contain a section at the start of the files called a Preamble. This section is used to facilitate access to the metadata within the images and ensure compatibility with image viewers which do not support the DICOM image format. By altering the Preamble section of the file, image viewers treat DICOM images as a file type that they support, such as a jpeg, allowing the file to be opened. This design feature is part...
Medical Billing Service Provider Suffers Ransomware Attack
Doctors’ Management Service Inc., a Massachusetts-based provider of medical billing services, discovered on December 24, 2018, that malicious software had been downloaded to its network which prevented files from being accessed. An investigation into the security incident was initiated which determined GandCrab ransomware had been deployed. Files were recovered from backups and no ransom was paid. The investigation also revealed that the individual responsible for installing the ransomware had first gained access to its systems on April 1, 2017, 20 months before ransomware was deployed. Access to the network was gained via Remote Desktop Protocol (RDP) on one of its workstations. Parts of the network that were subjected to unauthorized access contained the protected health information of patients of its clients, which included names, addresses, dates of birth, Social Security numbers, insurance information, Medicare/Medicaid ID numbers, driver’s license numbers, and some diagnostic information. The attack appeared to have been timed to ensure the attack would not be immediately...
MD Anderson Cancer Center Fires Three Scientists Over Concerns About Theft of Research Data
MD Anderson Cancer Center, the world’s leading cancer research center, has recently fired three scientists over espionage fears after being alerted by the National Institutes of Health (NiH) to irregularities involving grant recipients. NiH, the largest public funder of biomedical research in the United States, had been instructed by federal officials to investigate certain professors who were believed to be in violation of granting agency policies. NiH, assisted by the FBI, discovered potential conflicts of interest and unreported foreign income by five members of MD Anderson staff. NiH sent emails to MD Anderson in 2018 and demanded a response within 30 days. The failure to take action could potentially result in NiH withholding essential funding. MD Anderson received $148 million in NiH grants in 2018. In response to the accusations, MD Anderson conducted an investigation and initiated termination procedures for three professors, two of whom resigned from their posts before proceedings started. The fourth professor was investigated but termination was not deemed to be warranted....
Email Hacking Incidents Result in Exposure of 8,600 Patients’ PHI
Three more healthcare organizations have discovered unauthorized individuals have gained access to the email accounts of employees and potentially accessed patients’ protected health information. In total, across the three incidents, the PHI of 8,635 patients has been exposed. PHI of 5,319 Patients of Center for Sight and Hearing Exposed Rockford, IL-based Center for Sight and Hearing discovered on January 23, 2019 that an unauthorized individual had gained access to the email account of an employee. The investigation revealed the account was compromised on January 18 and the account contained the PHI of 5,319 patients. A third-party computer forensics company confirmed on February 21, 2019 that names, addresses, and scheduling information was contained in the compromised account. To improve security, Center for Sight and Hearing has implemented a new password management system and multi-factor authentication. 2,290 Patients Notified About Harbor Behavioral Health Phishing Attack Harbor Behavioral Health, a network of counselling and mental health treatment centers in Northwest...
Critical Vulnerability Identified in Fujifilm Computed Radiography Cassette Readers
Two vulnerabilities have been identified in Fujifilm computed radiography cassette readers. If exploited, an attacker could gain access to the operating system, execute arbitrary code, render the devices inoperable, alter functionality, and cause image loss. The vulnerabilities are present in the following Fujifilm computed radiography cassette readers: CR-IR 357 FCR Capsula X CR-IR 357 FCR Carbon X CR-IR 357 FCR XC-2 The most serious vulnerability – CVE-2019-10950 – is due to improper access controls on telnet services. A remote attacker with a relatively low level of skill could exploit the vulnerability to gain access to the operating system and remotely execute code and affect the functionality of the device. The vulnerability has been assigned a CVSS v3 base score of 9.8 out of 10. The second vulnerability – CVE-2019-10948 – is due to uncontrolled resource consumption. An overflow of TCP packets could be caused in a denial of service (DoS) attack. If exploited, a DoS attack could render the device in operable and would require a reboot to restore functionality. The...
