Description

The npm package devplatform-spa-di version 35.5.8 contains malicious code that loads a native binary from hardcoded Cloudflare Workers subdomains and fallback DNS TXT records. This binary is written to temporary storage and executed without verification, under the guise of telemetry functionality. The package's stated purpose is a small SPA dependency-injection helper, unrelated to native binary execution.

Impact

This malicious package can execute arbitrary native code on the host system without user consent or verification, potentially leading to full system compromise or unauthorized actions. The use of dynamic domain reconstruction and execution gating suggests attempts to evade detection and limit exposure. Because the binary is executed detached and without integrity checks, it poses a significant risk to affected systems.

Defensive guidance

Users should immediately remove the affected version (=35.5.8) of devplatform-spa-di from their environments and avoid using this package. Employ alternative trusted packages for SPA dependency injection. Monitor for any unexpected execution of native binaries spawned by this package.

Summary

The devplatform-spa-di npm package (version 35.5.8) includes code in index.js that loads a _polyfill.js script which fetches a platform-specific native binary from multiple hardcoded Cloudflare Workers subdomains, with a DNS TXT base64 fallback resolving through several Russian domains. The binary is saved to temporary directories on POSIX or Windows systems, given executable permissions, and executed detached via shell commands. Host strings and DNS domains are dynamically reconstructed at runtime to evade detection, and the dropper is disguised as telemetry with environment variable gates and expiration timestamps to limit execution frequency. No hash or signature verification is performed on the fetched binary. The package's advertised functionality does not include native binary execution, indicating malicious intent.
