Sections

ID	Name	Description
IF002.009	Exfiltration via Disk Media	A subject exfiltrates data using writeable disk media.
PR004.003	Removable Media File Exploration	The subject browses, searches, or navigates files stored on removable media to identify data of interest. This includes interaction with external storage devices such as USB flash drives, external hard drives, memory cards, or other mountable media connected to an endpoint. File exploration on removable media may involve directory traversal, file listing, previewing, or opening files directly from the mounted device. This activity can occur either on media introduced by the subject or on devices previously used for data staging or transfer.
