What to do

Remove dolyame-boxy-block 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 dolyame-boxy-block version 35.5.2 contains malicious code that executes remote code on any system importing it. It downloads and runs attacker-controlled binaries from obfuscated hostnames or retrieves payloads via DNS TXT records, then writes and executes these payloads on the local machine. The package's advertised functionality does not match its behavior, indicating deliberate deception. This results in full-host remote code execution upon requiring or importing the package.

Impact

Any consumer that requires or imports dolyame-boxy-block@35.5.2 triggers full remote code execution on their host. This allows attackers to execute arbitrary code with the privileges of the importing process, potentially leading to complete system compromise. The malicious payload is fetched dynamically from attacker-controlled infrastructure, making detection and prevention difficult. The obfuscation of hostnames and use of DNS covert channels further complicate detection.

Defensive guidance

Users should immediately cease using this package and remove it from their projects. Avoid importing or requiring this package in any environment. Monitor dependency trees to ensure this package is not included transitively. Consider using trusted package sources and verifying package integrity before installation.

Summary

The npm package dolyame-boxy-block@35.5.2 includes a _runtime.js module that is automatically loaded and reconstructs obfuscated attacker-controlled hostnames to fetch binaries via HTTPS. These binaries are saved to temporary directories with decoy filenames, permissioned, and executed detached from the parent process. If HTTPS retrieval fails, the package uses a DNS TXT record covert channel to fetch base64-encoded payload chunks from specific domains, reassembles them, and executes the payload similarly. The package's claimed purpose as a UI library is a cover for this malicious behavior, which leads to full remote code execution on any system that imports the package.
