Adversaries may use methods of capturing user input to obtain credentials or collect information. During normal system usage, users often provide credentials to various different locations, such as login pages/portals or system dialog boxes. Input capture mechanisms may be transparent to the user (e.g. Credential API Hooking) or rely on deceiving the user into providing input into what they believe to be a genuine service (e.g. Web Portal Capture).

Detects web-based credential phishing by analyzing traffic to suspicious URLs that mimic login portals and POST credential content.
Detects use of tools/scripts accessing input devices like /dev/input/* or evdev via suspicious processes lacking GUI context.
