What to do

Remove bnpl-blocks-analytics 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 bnpl-blocks-analytics version 35.3.8 contains malicious code that downloads and executes OS-specific binaries from obfuscated Cloudflare Workers hosts and fallback domains. These binaries are saved to temporary directories with disguised filenames, given executable permissions, and run without any signature or hash verification. The package includes a parallel dropper disguised as an analytics SDK that uses base64 decoding and similar execution techniques. Any system with this package installed or running should be considered fully compromised, and all secrets and keys on that system must be rotated. Removal of the package alone does not guarantee eradication of the malicious software.

Impact

Systems with bnpl-blocks-analytics version 35.3.8 installed or running are fully compromised, potentially allowing attackers to execute arbitrary code and maintain persistent control. All secrets and keys stored on such systems are at risk and should be considered exposed. The malicious payloads are executed without verification, increasing the risk of undetected compromise. Removal of the package does not guarantee removal of all malicious components, implying a deep system compromise.

Defensive guidance

Immediate removal of the bnpl-blocks-analytics package version 35.3.8 is recommended. All secrets and keys on affected systems should be rotated from a secure, uncompromised environment. Due to the high likelihood of full system compromise, affected systems should be considered untrusted and may require full reimaging or forensic analysis to ensure eradication of malicious components. Monitor for any unusual activity related to the described domains and filenames.

Summary

The bnpl-blocks-analytics npm package (version 35.3.8) contains embedded malicious code that, upon requiring the package, loads a script that downloads OS-specific binaries from dynamically assembled Cloudflare Workers domains and fallback domains resolved via DNS TXT records. These binaries are saved to temporary locations with filenames mimicking legitimate .NET diagnostic tools, permissioned to be executable, and then executed detached from the main process. No integrity checks such as signature or hash verification are performed on the downloaded payloads. Additionally, a secondary dropper is embedded in the telemetry.js library, which decodes base64 chunks and uses the same chmod and spawn execution pattern. The package effectively provides an attacker with full control over the compromised system. The vendor or source advisory does not mention any patch or remediation.
