Description

The npm package 'statist-browser-typed-client-mb.product.operations' version 20.4.9 contains malicious code that downloads and executes a binary payload from dynamically assembled external hosts. The payload is saved under disguised filenames in temporary directories and executed without integrity verification. The package masquerades this activity as telemetry, which contradicts its stated purpose as an Operations SDK.

Impact

The malicious package can execute arbitrary code on the host system by downloading and running an unverified binary payload. This can lead to full system compromise depending on the payload's capabilities. The lack of integrity checks and obfuscation techniques increase the risk of undetected malicious activity. The package's disguise as telemetry may cause users to trust it and overlook suspicious behavior.

Defensive guidance

Users should avoid using version 20.4.9 of the 'statist-browser-typed-client-mb.product.operations' package. Verify package authenticity before installation and monitor for suspicious network activity related to the described hostnames. Check vendor advisories or trusted security sources for updates or official fixes.

Summary

This threat involves a malicious npm package 'statist-browser-typed-client-mb.product.operations' at version 20.4.9. Upon module load, it unconditionally requires a bridge script that selects an OS and architecture-specific payload URL from obfuscated hostnames. It downloads a binary payload over HTTPS, with a fallback mechanism using DNS TXT records encoded in chunked base64 from a secondary domain. The binary is saved to temporary directories with disguised names, permissions are set to executable, and it is launched detached from the parent process using shell commands. There is no hash or signature verification of the downloaded payload. The package attempts to disguise this behavior as telemetry by writing state files and referencing environment variables for opt-out, but this does not align with its declared functionality.
