title: Hypervisor (T1062)
id: df00tech-t1062
status: experimental
description: "Adversaries may install a type-1 hypervisor below the operating system to achieve persistent, stealthy access that survives reboots and is hidden from the guest OS. A malicious hypervisor intercepts hardware-level operations and can conceal its presence from all software running above it, including security tools and the OS kernel. This technique has been deprecated by MITRE ATT&CK but remains relevant for detection engineering due to its theoretical use by sophisticated threat actors and nation-state groups targeting high-value environments. Practical implementations include Blue Pill-style subvirt attacks, malicious Xen-based hypervisors, or abuse of legitimate hypervisor platforms (Hyper-V, VMware) as persistence anchors. Detection relies on pre-installation indicators (hypervisor binary drops, boot configuration changes, driver installs) since post-installation detection from inside the guest OS is unreliable."
