Description

The npm package 'twork-data-services-sme-agent-company-relation' version 20.5.3 contains malicious code that downloads and executes a native binary from multiple external hosts. The package uses obfuscation techniques to evade detection, writes the payload to temporary directories with disguised names, sets executable permissions, and runs it detached from the main process. A secondary dropper labeled as an 'Analytics SDK' also executes arbitrary code. Installation of this package results in full system compromise, requiring immediate secret and key rotation and package removal.

Impact

Any system with this package installed or running should be considered fully compromised. The attacker gains remote code execution capabilities through the downloaded native binary and secondary dropper. All secrets and keys stored on the compromised system are at risk and must be rotated immediately from a secure environment. Removal of the package alone does not guarantee eradication of the malicious software or attacker persistence.

Defensive guidance

Remove the 'twork-data-services-sme-agent-company-relation' package version 20.5.3 immediately from all affected systems. Rotate all secrets, credentials, and keys that were stored or used on compromised systems from a different, trusted machine. Conduct a thorough investigation for persistence mechanisms or additional malware installed by the attacker.

Summary

The malicious npm package 'twork-data-services-sme-agent-company-relation' version 20.5.3 unconditionally loads an initialization script that dynamically assembles hostnames to fetch a platform-specific native binary from multiple *.workers.dev domains. It uses DNS TXT record fallback channels for additional payload retrieval. The payload is saved to temporary directories with randomized disguised filenames, permissions are set to executable, and the binary is spawned detached via shell commands. Additionally, a secondary dropper in 'lib/telemetry.js' uses obfuscated child process spawning and base64 decoding to execute a written file. There is no integrity verification or relation to the package's declared purpose, indicating deliberate malicious intent. The package effectively grants full control of the infected system to an external entity.
