🚨 A privacy researcher just dropped something every Claude user needs to read.
The claim: installing Claude Desktop may silently inject a "native messaging bridge" into your browsers.
Not just the browsers you use.
ALL of them.
Including ones that are not even supported.
It pre-authorizes extensions that run in the background.
Users are reportedly NOT clearly informed this is happening.
The source is calling it "spyware-like behavior."
This has NOT been independently confirmed yet.
Anthropic has not responded publicly.
But if true, this is not a small privacy footnote.
This is a company that built its entire brand on being the "safe and trustworthy" AI lab getting caught installing hidden system components on your machine without telling you.
The trust gap between what Anthropic says and what the software apparently does would be the story of the year.
Watching this closely.
Will update the moment Anthropic responds.
