Typical severity: Medium. Likelihood of attack: Low. Adversaries may attempt to obtain information about attached peripheral devices and components connected to a computer system. Examples may include discovering the presence of iOS devices by searching for backups, analyzing the Windows registry to determine what USB devices have been connected, or infecting a victim system with malware to report when a USB device has been connected. This may allow the adversary to gain additional insight about the system or network environment, which may be useful in constructing further attacks.
Identify programs that may be used to acquire peripheral information and block them by using a software restriction policy or tools that restrict program execution by using a process allowlist.
