What to do

Remove twork-data-services-product-design-data from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package 'twork-data-services-product-design-data' version 20.1.5 contains malicious code that downloads and executes platform-specific binaries from obfuscated external domains. These binaries are saved to temporary directories with disguised filenames, given executable permissions, and launched in detached processes. The package also includes a secondary dropper disguised as a telemetry SDK using obfuscation techniques to evade static analysis. Any system with this package installed or running should be considered fully compromised, and all secrets and keys on the system must be rotated immediately. Removal of the package alone may not eliminate all malicious components due to potential full system compromise.

Impact

Systems with this package installed or running are considered fully compromised. The attacker gains remote code execution capabilities via downloaded binaries executed on the host. This can lead to complete system takeover, unauthorized data access, and potential persistence. All secrets and keys stored on the compromised system are at risk and must be rotated immediately. Simply removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the attacker.

Defensive guidance

Immediate removal of the 'twork-data-services-product-design-data' package version 20.1.5 is recommended. Due to the high likelihood of full system compromise, all secrets and keys stored on the affected system should be rotated from a separate, trusted environment. Incident response should consider the possibility of persistent backdoors or additional malware beyond the package itself. Monitor for any suspicious activity and consider full system reimaging if feasible.

Summary

This threat involves a malicious npm package 'twork-data-services-product-design-data' version 20.1.5 that, upon requiring its main module, downloads a platform-specific binary from obfuscated Cloudflare Workers subdomains and fallback DNS TXT records. The binary is saved under disguised filenames in temporary directories, permissioned as executable, and executed detached from the main process. A parallel dropper is embedded in a telemetry.js module, which similarly reconstructs and executes payloads using base64 chunk assembly and obfuscated function calls to evade detection. The obfuscation of command and control hostnames, DNS exfiltration domains, and child process invocation is deliberate to avoid static analysis detection. The package effectively grants full control of the infected system to an external attacker.
