An attacker's malware would also behave differently to the original hypervisor, resulting in changes to network, processing and disk activity, which should cause alarm bells for security ...

In other words, if any customer with a VM inside a vulnerable hosting environment is compromised, an attacker might be able to take control of the host environment hypervisor.

“The impact here is huge, an attacker who has compromised a hypervisor can go on to compromise any of the other virtual machines that share the same hypervisor,” Stephen Fewer, principal ...

Microsoft security strategist Steve Riley has answered claims that the company's hypervisor software could be maliciously replaced on PCs without administrators knowing.

Using QEMU, the attackers established a network tunnel from the targeted internal host that didn't have internet access to a pivot host with internet access, which in turn connects to the attacker ...

Ideally, hypervisors are air-gapped, which makes it more difficult for intruders to make their way in. Virtual Patching This advanced capability can be enabled by solutions like EDR or some firewalls.

An algorithm assigns virtual machines to hypervisors in a way that minimizes the chances of rendering a highly secure client vulnerable to attack through a client with weaker security.

The Xen Project, which oversees the open source Xen hypervisor, yesterday patched a seven-year-old vulnerability that allows an attacker to escape a guest virtual machine and attack the host ...

Broadcom, which acquired VMware in 2023, said that the vulnerabilities (tracked as CVE-2025-22224, CVE-2025-22225, and CVE-2025-22226) could allow an attacker with administrator or root privileges ...
