Falsedrive

Falsedrive is a term used in computer storage and security contexts to describe a storage volume that is presented to a host system as a disk, but does not correspond to a traditional physical drive or a simple disk image. In practice, falsedrives are implemented by software that intercepts drive enumeration calls or by virtual disk drivers, allowing a system to see a volume with specific properties (name, size, serial) that may not reflect real hardware.

They are used in both legitimate and dubious contexts. For testing and sandboxing, engineers may deploy falsedrive implementations to simulate removable media or to emulate different storage configurations without risking hardware. In other cases, attackers or scammers may rely on falsedrives to deceive users, exfiltrate data, or install software under the guise of a legitimate-sounding external drive.

Technical methods range from file system filters and kernel-mode drivers to user-space emulation layers that mimic USB or SATA devices. Characteristics such as capacity, volume label, and device serial can be fabricated or masked. Because the volume appears in standard file explorers and system utilities, it can be difficult for unsuspecting users to distinguish falsedrives from real hardware.

Detection and mitigation emphasize provenance verification and behavioral analysis. Security tools may monitor for unsigned drivers, unusual drive enumeration patterns, or inconsistencies between reported device properties and known hardware. Administrators can reduce risk by disabling auto-run features, enforcing driver signing, maintaining an inventory of installed storage drivers, and using integrity checks to detect tampered or unexpected virtual drives. In testing environments, isolation and auditing are advised to avoid unintended data exposure.
