react-context-form-tdsss@9.0.0 is a dependency-confusion payload. package.json declares scripts.preinstall="node index.js", and index.js issues an HTTPS GET to a hardcoded interactsh/OAST subdomain (d8v0o1a9io6mjndcpbgghpfmkcgcm6dno.oast.online/npm-installed) on install. This beacon discloses the installer's public IP and confirms code execution on the installer's host to the operator of the OAST listener. The package.json description self-identifies as a dependency-confusion PoC and declares a self-dependency, the shape used to squat an internal/private package name on the public registry so that resolution in a victim environment pulls and executes this code. Installing this package causes outbound network beaconing on the installer's machine without consent.
