The npm package devplatform-react-query-clients version 35.7.7 contains malicious code that downloads and executes unauthenticated platform-specific binaries from anonymous Cloudflare Workers subdomains. These binaries are saved to temporary directories with randomized names and executed with elevated permissions, enabling full remote code execution on any environment that installs or imports this package. The malicious behavior is obfuscated to evade detection and disguised as telemetry or analytics functionality. No patch or remediation guidance is currently provided.
