Adversaries may collect data stored in the clipboard from users copying information within or between applications.

For example, on Windows adversaries can access clipboard data by using clip.exe or Get-Clipboard.[1],[2],[3] Additionally, adversaries may monitor then replace users’ clipboard with their data (e.g., Transmitted Data Manipulation).[4]

macOS and Linux also have commands, such as pbpaste, to grab clipboard contents.[5]
