Issue/Introduction

DLP Endpoint does not detect clipboard copy/paste of raw image data

DLP Endpoint fails to detect or block raw image data (e.g., from Paint or Snipping Tool) when pasted into web browser / applications like Gmail, Outlook.

Environment

Release: 16.x and Higher

Cause

The DLP Agent specifically looks for "meaningful text" to extract and does not generate a detection request if no text is present in the clipboard content. 

Resolution

At the moment, in our Clipboard monitoring logic for copying and pasting "content", we only consider the formats from which the meaningful text be extracted.

In the above case, we do not get any text that could be extracted from the image. Hence the detection request is not generated.
