Change Healthcare Ransomware Attack Having Massive Impact on Providers
The outage at Change Healthcare that occurred on February 21, 2024, as a result of a Blackcat ransomware attack is taking its toll on the small practices and pharmacies that rely on its systems, many of which have now been offline for 9 days. The outage has meant that doctors have been left unable to check whether patients are eligible for treatment and pharmacies have been unable to fill prescriptions electronically, resulting in delays to patient care and huge backlogs. Clerical staff are overwhelmed and are having to work longer hours and manually call in prescriptions and revenue cycles have ground to a halt. Smaller practices especially are experiencing major financial difficulties as they have been unable to receive reimbursement from insurance companies which means they have been unable to pay for operational expenses such as medical supplies and payroll. Many practices operate on very thin margins and any extended disruption to their revenue streams could prove to be catastrophic. Some providers are having to make difficult decisions about whether to remain open, while...

Five Eyes Agencies Warn of Ongoing Exploitation of Ivanti Connect Secure and Policy Secure Flaws
The Five Eyes Cybersecurity Agencies have issued a warning that previously disclosed vulnerabilities in Ivanti Connect Secure and Ivanti Policy Secure gateways are being actively exploited by multiple threat actors and have been since early December 2023. The flaws – CVE-2023-46805, CVE-2024-21887, and CVE-2024-21893 – affect all supported versions (9.x and 22.x) and can be chained to bypass authentication, craft malicious requests, and execute arbitrary commands with elevated privileges. According to the alert, Ivanti’s internal and previous external Integrity Checker Tool (ICT) failed to detect malicious activity associated with exploitation. CISA demonstrated in a test environment that the ICT is not sufficient to detect compromise and that it is possible to gain root-level persistence despite issuing factory resets. Alphabet’s Mandiant has been investigating the exploitation of the zero day vulnerabilities and said the exploitation had likely impacted thousands of devices across multiple industry verticals. Some of those attacks were linked with a suspected Chinese cyber...
High Severity Vulnerabilities Identified in MicroDicom DICOM Viewer
Two high-severity vulnerabilities have been identified in the free-to-use MicroDicom DICOM Viewer, which is used to view and manipulate DICOM images. Successful exploitation of the vulnerabilities could lead to remote code execution and memory corruption. The first is a heap-based buffer overflow vulnerability tracked as CVE-2024-22100 which can be exploited in a low-complexity attack by tricking a user into opening a malicious DCM file, which would allow a remote attacker to execute arbitrary code on vulnerable versions of the DICOM Viewer. The second vulnerability is an out-of-bounds write issue due to a lack of proper validation of user-supplied data. Successful exploitation of the flaw could result in memory corruption within the application. The vulnerability is tracked as CVE-2024-25578. The vulnerabilities affect MicroDicom DICOM Viewer versions 2023.3 (Build 9342) and prior versions and have been fixed in version 2024.1. Users have been advised to update to the latest version as soon as possible. There are currently no indications that the vulnerabilities have been...
