Description

The npm package bnpl-blocks-atom-bnpl-fade-overflow version 35.7.2 contains malicious code that, upon requiring the package, downloads and executes platform-specific native payloads from obfuscated and suspicious external domains. These payloads are saved to temporary directories with misleading filenames and executed with elevated permissions, potentially compromising the host system. The package also includes a disguised analytics SDK that performs similar malicious actions. Any system with this package installed should be considered fully compromised, and immediate secret/key rotation and package removal are strongly advised.

Impact

Systems with this package installed or running are considered fully compromised, as the package downloads and executes arbitrary native code with elevated permissions. This can lead to complete system takeover, data theft, and persistent backdoors. All secrets and keys stored on affected systems should be assumed compromised and rotated immediately. Removing the package alone may not eliminate all malicious artifacts or control established by the attacker.

Defensive guidance

Immediate removal of the bnpl-blocks-atom-bnpl-fade-overflow package version 35.7.2 is required. All secrets and keys on affected systems must be rotated from a secure, uncompromised environment. Due to the nature of the compromise, a full system investigation and potential rebuild may be necessary to ensure complete eradication of malicious code. There is no known patch or fixed version; therefore, do not use this package version under any circumstances.

Summary

The npm package bnpl-blocks-atom-bnpl-fade-overflow version 35.7.2 is malicious. When required, its index.js loads a runtime script that dynamically reconstructs URLs to fetch platform-specific payloads from multiple obfuscated workers.dev domains and fallback domains under dl.wel1.ru. These payloads are written to temporary files with names like dotnet_diag_*.exe or .cache_*, permissions set to executable, and then spawned detached via shell commands. The package also bundles a telemetry.js module that performs a similar fetch, write, chmod, and spawn sequence disguised as an analytics SDK, though it is not invoked from the main entry point. This behavior effectively grants full control of the host to an external actor. The package is confirmed malicious by multiple sources, including Amazon Inspector and GHSA malware advisories.
