Malicious code in @medisend/webview-bridge (npm)
Details
package.json declares a postinstall lifecycle script that runs curl to https://webhook.site/74ed1be3-96d6-48c3-932b-6b1dbabaff97 with query parameters populated from $(whoami), $(hostname), $(pwd), $(ls -la), and $(node -v). On every npm install the installer's username, hostname, working directory, a directory listing of the install location, and Node.js version are sent to a third-party webhook.site collector controlled by whoever provisioned that endpoint. The package publishes under the @medisend scope and its description states a dependency-confusion test referencing a third-party VDP; an installer whose internal tooling resolves the public registry version instead of an internal @medisend package will trigger this exfiltration automatically.
