Increased Risk of Cyber and Ransomware Attacks Over Thanksgiving Weekend
The Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have warned organizations in the United States about the increased risk of cyberattacks over Thanksgiving weekend. Cyber threat actors are often at their most active during holidays and weekends, as there are likely to be fewer IT and security employees available to detect attempts to breach networks. Recent attacks have demonstrated holiday weekends are prime time for cyber threat actors, with the Las Vegas Cancer Center one of the most recent victims of such an attack on the Labor Day weekend. The warning applies to all organizations and businesses, but especially critical infrastructure firms. Cyber actors around the world may choose Thanksgiving weekend to conduct attacks to disrupt critical infrastructure and conduct ransomware attacks. CISA and the FBI are urging all entities to take steps to ensure risk is effectively mitigated ahead of the holiday weekend to help prevent them from becoming the next victim of a costly cyberattack. Steps that should be taken immediately...
HC3 Warns Healthcare Sector About Risk of Zero-day Attacks
The HHS’ Health Sector Cybersecurity Coordination Center (HC3) has issued a threat brief warning the healthcare and public health sector about an increase in financially motivated zero-day attacks, outlining mitigation tactics that should be adopted to reduce risk to a low and acceptable level. A zero-day attack leverages a vulnerability for which a patch has yet to be released. The vulnerabilities are referred to as zero-day, as the developer has had no time to release a patch to correct the flaw. Zero-day attacks are those where a threat actor has exploited a zero-day vulnerability using a weaponized exploit for the flaw. Zero-day vulnerabilities are exploited in attacks on all industry sectors and are not only a problem for the healthcare industry. For instance, in 2010, exploits were developed for four zero-day vulnerabilities in the “Stuxnet” attack on the Iranian nuclear program, which caused Iranian centrifuges to self-destruct to disrupt Iran’s nuclear program. More recently in 2017, a zero-day vulnerability was exploited to deliver the Dridex banking Trojan. While it...

University Hospital Newark Notifies More Than 19,000 Individuals About Historic Insider Theft
University Hospital Newark (NY) has discovered the protected health information of thousands of patients has been acquired by a former employee, who accessed the information without authorization over the course of a year. That information was subsequently disclosed to other individuals who were also not authorized to view the information. Insider breaches such as this are fairly common, although what makes this case stand out is when the access occurred. In its substitute breach notice, University Hospital Newark said the unauthorized access occurred between January 1, 2016, and December 31, 2017. The former employee had been provided with access to patient data to complete work duties but had exceeded the authorized use of that access and had viewed patient data not pertinent to job functions. The types of information viewed and obtained by the individual included names, addresses, dates of birth, Social Security numbers, health insurance information, medical record numbers, and clinical information related to care patients received at University Hospital. University Hospital...
Vulnerabilities Identified in Philips IntelliBridge, Patient Information Center and Efficia Patient Monitors
Five vulnerabilities have been identified that affect the IntelliBridge EC 40 and EC 80 Hub, Philips Patient Information Center iX, and Efficia CM series patient monitors. IntelliBride EC 40 and EC 80 Hub Two vulnerabilities have been identified that affect C.00.04 and prior versions of the IntelliBridge EC 40 and EC 80 Hub. Successful exploitation of the vulnerabilities could allow an unauthorized individual to execute software, change system configurations, and update/view files that may include unidentifiable patient data. The first vulnerability is due to the use of hard-coded credentials – CVE-2021-32993 – in the software for its own inbound authentication, outbound communication to external components, or the encryption of internal data. The second vulnerability is an authentication bypass issue – CVE-2021-33017. While the standard access path of the product requires authentication, an alternative path has been identified that does not require authentication. Both vulnerabilities have been assigned a CVSS v3 severity score of 8.1 out of 10. Philips has not yet issued an...
