An organization is implementing a virtualized thin-client solution for normal user computing and access. During a review of the architecture, concerns were raised that an attacker could gain access to multiple user environments by simply gaining a foothold on a single one with malware. Which of the following reasons BEST explains this? A. Malware on one virtual environment could enable pivoting to others by leveraging vulnerabilities in the hypervisor. B. A worm on one virtual environment could spread to others by taking advantage of guest OS networking services vulnerabilities. C. One virtual environment may have one or more application-layer vulnerabilities, which could allow an attacker to escape that environment. D. Malware on one virtual user environment could be copied to all others by the attached network storage controller.
