This Tool Can Help Identify Leakers Who Copy and Paste Secret Info

I rarely think that the text I’m copying and pasting has something hidden within it that could reveal my sources. And I probably should worry about that because it’s incredibly easy to hide invisible characters—so-called “zero-width” characters—within text and use those as a watermark or fingerprint of sorts. In some situations, that could reveal to the original author who you are, or the fact that you copy pasted the original text and put it somewhere else.
