NSA & CISA Issue Guidance on Hardening Security and Managing Kubernetes Environments
Kubernetes is a popular open-source cloud solution for deploying and managing containerized apps. Recently there have been several security breaches where hackers have gained access to poorly secured Kubernetes environments to steal sensitive data, deploy cryptocurrency miners, and conduct denial-of-service attacks. This month, security researchers discovered Kubernetes clusters were being targeted by cyber actors who were exploiting misconfigured permissions for the web-facing dashboard of Argo Workflows instances. In these attacks, the computing power of Kubernetes environments were harnessed for mining cryptocurrencies. In another attack, a vulnerability in the Kubernetes API Server was being exploited to steal sensitive data. In light of these attacks, the National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) have issued a 52-page technical report that includes detailed guidance on how to correctly set up and manage Kubernetes environments to make it harder for the environments to be compromised by hackers. The report includes details...
Email Account Breaches Reported by Prestera Center and Wisconsin Institute of Urology
Prestera Mental Health Center in West Virginia has started notifying 2,152 individuals about a security breach involving employee email accounts. On or around April 1, 2021, Prestera Center learned that certain employee email accounts had been subjected to unauthorized access between August 2020 and September 2020. While it was possible to confirm that there had been unauthorized access, it was not possible to tell whether any patient data had been viewed or acquired. A review was conducted to determine the types of information that were present in the email accounts and which individuals had been affected. The types of data in the account varied from individual to individual and may have included names, addresses, dates of birth, state identification card numbers, Social Security numbers, financial account information, medical information, and health insurance information. Upon discovery of the breach, prompt action was taken to secure the accounts to prevent any further unauthorized access. Policies and procedures have since been reviewed and updated, and additional safeguards...
Multiple Critical Vulnerabilities Identified in Pneumatics System Used in 2,300 U.S. Hospitals
Nine critical vulnerabilities have been identified in the Nexus Control Panel of Swisslog Healthcare Translogic Pneumatic Tube System (PTS) stations, which are used in more than 80% of major hospitals in the United States. Pneumatic tube systems are used to rapidly send test samples and medications around hospitals and the vulnerable PTS stations are present in 3,000 hospitals worldwide, including 2,300 in the United States. The vulnerabilities, collectively named ‘PwnedPiper’, were discovered by researchers at Armis Security. In total, 9 critical flaws were identified in the Nexus Control Panel and the firmware of all current models of Translogic PTS stations are affected. The vulnerabilities identified by the researchers are common in Internet of Things (IoT) devices but are far more serious in pneumatic tube systems, which are part of hospitals’ critical infrastructure. The Armis researchers pointed out that these systems are prevalent in hospitals, yet they have never been thoroughly analyzed or researched. The flaws could be exploited by a threat actor to cause denial of...
Star Refining & Express MRI Report Phishing Attacks
The Peachtree Corners, GA-based medical imaging center, Express MRI, has started notifying patients that some of their protected health information has been exposed in a historic data breach. Express MRI discovered on July 10, 2020 that an unauthorized individual had gained access to one of its email accounts and used that account to send unauthorized emails. The incident was investigated at the time, but it was determined that no patient information had been accessed. A secondary review of the security breach was conducted on June 10, 2021, and while no specific evidence was uncovered that indicated there had been unauthorized data access or data theft, Express MRI concluded that it was not actually possible to totally rule out unauthorized data access or exfiltration, therefore breach notification letters were warranted. A review of the compromised account confirmed the following information may have been accessed or acquired: Names, addresses, email addresses, dates of birth, patient ages, referring physician names, body part scanned, and whether the scan was related to a...
Harris County, TX: PHI of 26,000 Individuals Exposed Online
Harris County in Texas has discovered the personal and health information (PHI) of thousands of individuals has been exposed online and was potentially accessed by unauthorized individuals. Under Harris County’s legally required reporting obligations, information is provided to the Harris County Justice Administration Department which includes System Person Numbers, which are unique identifiers that are assigned to individuals by the Harris County jail system. In addition to those numbers, some limited health information is provided related to the medical care individuals received at the County’s Jail Clinic, which includes health histories, diagnoses, and/or prescription information. The inadvertent disclosure of sensitive information was discovered by Harris County officials on July 9, 2021. Harris County determined that between March 15, 2021 and May 22, 2021, the above types of information were inadvertently made available on the Justice Administration Department’s website.
