Virtualisation security covers hypervisors, virtual machines, and isolated workloads, where flaws or misconfiguration can expose systems and data.

Background for this topic.
Virtualisation uses software to divide or simulate computing resources so multiple isolated virtual machines (VMs) can share a physical host. Each VM can run its own operating system and applications; a hypervisor controls access to the host’s processors, memory, storage and devices. The term can also include virtual networks and storage, while containers provide a related but less isolated form of workload virtualisation.
Security depends on the hypervisor and its management plane being securely configured, patched and access-controlled. A hypervisor vulnerability or misconfiguration can expose data across VMs, and a VM escape can allow code running in one guest to reach the host or other guests. Virtual machine images, templates and snapshots may retain credentials or sensitive data and therefore require inventory, integrity checks, encryption and controlled retention. Network segmentation between virtual workloads should be enforced through explicit policies rather than assumed from virtual separation. These controls also support reliable investigation and recovery by preserving trustworthy images and records of administrative changes.
Cybersecurity researchers have discovered a new Linux variant of a remote access trojan (RAT) called BIFROSE (aka Bifrost) that uses a deceptive domain mimicking VMware
A new Linux variant of the Bifrost remote access trojan (RAT) employs several novel evasion techniques, including the use of a deceptive domain that was made to appear as part of VMware. [...]
