Description

The npm package 'volna-boxy-di-test' version 20.3.8 contains malicious code that downloads and executes platform-specific payloads from command and control (C2) servers. It disguises its activity as telemetry and analytics, uses obfuscated hostnames and filenames, and attempts to evade detection by suppressing re-execution. Installation of this package can lead to full system compromise.

Impact

Installation or execution of this package can lead to full compromise of the affected system. The attacker gains the ability to execute arbitrary code via downloaded payloads, potentially leading to unauthorized access, data theft, and persistent control. Secrets and keys stored on the compromised system are at risk and should be considered exposed.

Defensive guidance

The package should be immediately removed from any affected systems. Due to the high likelihood of full system compromise, all secrets and keys stored on the affected machine must be rotated from a different, secure system. Monitor for any signs of persistent malicious activity and consider rebuilding compromised systems.

Summary

The 'volna-boxy-di-test' npm package (version 20.3.8) acts as a dropper by loading a compatibility script that selects a platform-specific payload path. It reconstructs C2 hostnames at runtime from split string fragments, including domains such as oob-worker.cf10*-*.workers.dev and a DNS TXT chunked-base64 fallback at *.dl.well1.site. The package fetches unpinned, unhashed binaries over HTTPS, writes them to temporary directories under disguised filenames (e.g., .cache_<hex>, dotnet_diag_<hex>.exe), sets executable permissions on Unix, and spawns the binaries detached via shell commands. It spoofs the User-Agent to mimic legitimate node-fetch traffic and uses environment variables and TTL flag files to suppress repeated execution. The package falsely presents itself as a test harness, but the fetched code, hosts, and filenames do not align with this purpose. According to the GHSA malware advisory, any system with this package installed should be considered fully compromised, and all secrets and keys must be rotated from a separate system.
