Hyperjacking refers to an attacker gaining unauthorized, privileged control over the hypervisor layer itself, either by installing a malicious rogue hypervisor beneath the legitimate one or by exploiting the existing hypervisor's control plane. Because the hypervisor sits below and mediates every guest virtual machine running on that physical host, compromising it grants the attacker a position of total control over all VMs hosted there: the attacker can inspect, modify, redirect, or intercept traffic and memory for any guest, effectively bypassing security controls that operate inside the individual VMs, since those controls have no visibility into or authority over the compromised layer beneath them. This makes hyperjacking exceptionally dangerous, as a single compromised hypervisor can expose every tenant workload on that host simultaneously. Preventing new VM creation (A), causing an unexpected shutdown (B), and limiting network traffic management (C) each describe narrow, specific functional impairments, but none captures the defining and most consequential characteristic of hyperjacking, which is the attacker gaining broad, stealthy control over the entire virtualized environment rather than simply degrading or disabling a single hypervisor function. Full control over all VMs is the correct and most likely consequence.

A remote backup service refers to a model in which a client-side backup agent, installed within the organization's own environment, transfers data across a network connection to backup infrastructure hosted by a cloud provider, physically located outside the organization's own premises. The scenario describes exactly this: a cloud backup agent moving on-premises or client data to backup infrastructure residing in the cloud, which matches the defining characteristic of a remote backup service, data originating locally and being protected at a remotely hosted destination via an agent-based transfer mechanism. Local backup service (A) describes protecting data to storage that remains within the organization's own physical premises, the opposite of what the scenario describes, since the destination here is explicitly cloud-based infrastructure, not a local target. Replicated backup service (C) is not a standard, distinctly defined cloud backup service category in this context and does not precisely describe the agent-based, remote transfer mechanism at play. Cloud-to-cloud backup (D) specifically describes protecting data that already originates within one cloud (such as SaaS application data) by copying it to a separate cloud environment, a different scenario from an on-premises agent backing up to cloud infrastructure, which is the case described here. Remote backup service is correct.

Image-based backup captures a complete, consistent snapshot of an entire virtual machine, its operating system, configuration, installed applications, and data, as a single unit at the hypervisor level, typically without requiring an agent inside the guest OS. This makes it uniquely suited to restoring an entire VM quickly and reliably, since the whole machine state, not just individual files, is preserved and can be powered back on essentially as it existed at capture time, which is invaluable for full disaster recovery or bare-metal-style VM restoration. Restoring individual files (A) is technically possible from an image, usually via file-level recovery tools that mount the image, but it is not the use case the technology is uniquely optimized for; dedicated file-level backup handles that more efficiently. Backing up application data only (B) understates the scope of image-based backup, which captures the full machine rather than isolating application data alone, and is arguably better served by application-aware agent-based backup for granular, consistent application recovery. Incremental backups (C) describe a backup frequency and data-capture method that can be applied to image-based backups but is not itself the unique use case image-based backup solves. Full VM restoration is the defining strength.
