Description
The npm package devplatform-react-mcp version 35.5.6 is a malicious dropper disguised as a React MCP SDK. When loaded, it dynamically assembles hostnames to download and execute attacker-controlled binaries on the host system. It uses runtime string concatenation to evade static detection and spawns these binaries detached from the main process. The package has no legitimate native build purpose and its only observable behavior is fetching and running opaque payloads.
