According to a post by SlowMist CISO @im23pads on the X platform, Claude Desktop has been exposed for secretly writing browser backdoor files. When users install the Claude Desktop application, it writes a special file to all Chromium-based browsers on the computer without the user's knowledge. This file acts as a pre-authorized backdoor, which, when used in conjunction with specific browser extensions, can grant complete control over the user's browser.
