HC3: Cobalt Strike Penetration Testing Framework Increasingly Used in Cyberattacks on Healthcare Organizations
The HHS’ Health Sector Cybersecurity Coordination Center (HC3) has issued a threat brief for the healthcare industry warning about the use of the Cobalt Strike penetration testing tool by cyber threat actors. Cobalt Strike is a powerful red team tool used by penetration testers when conducting risk and vulnerability assessments, but it can also be abused and is increasingly being used by cyber threat actors in attacks on the healthcare and public health sector. Cobalt Strike can be used for reconnaissance to gain valuable information about the target infrastructure to allow threat actors to determine the best use of their time when attacking healthcare networks. The system profiler function can be used to discover client-side applications used by a target and provides version information. The system profiler starts a local web server, fingerprints visitors, identifies internal IP addresses behind a proxy, and obtains reconnaissance data from the weblog, applications, and provides information on targets. Cobalt Strike includes a spear phish tool that can be used to create and send...
3 Medium Severity Vulnerabilities Identified in Philips MRI Solutions
Three medium severity vulnerabilities have been identified in Philips MRI products which, if exploited, could allow an unauthorized individual to run software, modify the device configuration, view and updates files, and export data, including protected health information (PHI), to an untrusted environment. Aguilar found insufficient access controls which fail to restrict access by unauthorized individuals (CVE-2021-3083), the software assigns an owner who is outside the intended control sphere (CVE-2021-3085), and sensitive data is exposed to individuals who should not be provided with access (CVE-2021-3084). Each of the vulnerabilities has been assigned a CVSS V3 base score of 6.2 out of 10. The vulnerabilities were identified by Secureworks Adversary Group consultant, Michael Aguilar, and affect Philips MRI 1.5T: Version 5.x.x, and MRI 3T: Version 5.x.x. Aguilar reported the flaws to Philips and a patch has been scheduled for release by October 2022. In the meantime, Philips recommends implementing mitigating measures to prevent the vulnerabilities from being exploited. The...
