Description

The npm package sme-rko-finance-front-operations-widget-impl version 35.8.1 contains malicious code that downloads and executes a native binary from multiple Cloudflare Workers hosts and fallback domains. The binary is saved to disguised temporary file paths and executed without integrity verification. The malicious behavior is hidden under the guise of telemetry functionality with an opt-out mechanism. This package is not a cloud service and no official patch or remediation guidance is provided.

Impact

This malicious package can execute arbitrary native code on the host system, potentially leading to full system compromise or unauthorized actions. The lack of integrity checks and use of obfuscated delivery mechanisms increase the risk of undetected exploitation. However, there are no known exploits in the wild reported at this time.

Defensive guidance

Users should immediately remove the affected version (=35.8.1) of the sme-rko-finance-front-operations-widget-impl package from their environments. Avoid using this package until a trustworthy update or advisory is issued. Monitor for any unusual activity related to this package and verify dependencies before installation.

Summary

The sme-rko-finance-front-operations-widget-impl npm package version 35.8.1 includes code that dynamically reconstructs hostnames to fetch an opaque native executable from Cloudflare Workers and fallback domains. The executable is saved to temporary directories with names resembling system caches or .NET diagnostics files, made executable, and launched detached from the main process. The package uses a marker file to prevent repeated execution. The malicious payload is disguised as telemetry functionality with an opt-out flag, lacks any pinning or hash verification, and is delivered from hosts unrelated to the declared publisher.
