Capture Clipboard Data
Adversaries may abuse Clipboard Manager APIs to obtain sensitive information copied to the global clipboard. For example, passwords being copy-and-pasted from a password manager app could be captured by another application installed on the device.
ClipboardManager.OnPrimaryClipChangedListener can be used by applications to register as a listener and monitor the clipboard for changes.
Android 10 mitigates this technique by preventing applications from accessing clipboard data unless the application is on the foreground or is set as the device’s default input method editor (IME).
Applications could be vetted for their use of the clipboard manager APIs with extra scrutiny given to application that make use of them.

Capturing clipboard content can be difficult to detect, and therefore enterprises may be better served focusing on detection at other stages of adversarial behavior.
