T1458 Replication Through Removable Media

Adversaries may move onto devices by exploiting or copying malware to devices connected via USB. In the case of Lateral Movement, adversaries may utilize the physical connection of a device to a compromised or malicious charging station or PC to bypass application store requirements and install malicious applications directly. In the case of Initial Access, adversaries may attempt to exploit the device via the connection to gain access to data stored on the device. Examples of this include: • Exploiting insecure bootloaders in a Nexus 6 or 6P device over USB and gaining the ability to perform actions including intercepting phone calls, intercepting network traffic, and obtaining the device physical location. • Exploiting weakly-enforced security boundaries in Android devices such as the Google Pixel 2 over USB. • Products from Cellebrite and Grayshift purportedly that can exploit some iOS devices using physical access to the data port to unlock the passcode.
