Description

The npm package bnpl-blocks-atom-bnpl-link-avatar version 35.4.8 contains malicious code that downloads and executes an opaque binary from untrusted Cloudflare Workers hostnames and fallback domains. The binary is saved to temporary directories with disguised names and executed without integrity verification. The package's public API is a no-op stub, indicating it is likely a typosquatting or dependency confusion lure designed solely to drop and run malicious code. Any system with this package installed should be considered fully compromised.

Impact

Installation or execution of this package results in the download and execution of an unverified opaque binary from attacker-controlled infrastructure, leading to full compromise of the affected system. All secrets and keys stored on the compromised system should be considered exposed and require immediate rotation from a secure environment. Removing the package alone does not guarantee removal of all malicious components or persistence mechanisms.

Defensive guidance

Immediate removal of the bnpl-blocks-atom-bnpl-link-avatar package version 35.4.8 is recommended. All secrets and credentials on affected systems should be rotated from a different, trusted machine. Due to the nature of the compromise, assume full system compromise and consider rebuilding the affected systems. Monitor for any signs of persistence or additional malicious activity resulting from this package installation.

Summary

The npm package bnpl-blocks-atom-bnpl-link-avatar version 35.4.8, upon being required, loads a polyfill script that selects a platform-specific path and downloads a binary over HTTPS from hardcoded Cloudflare Workers hostnames and fallback DNS-TXT base64 encoded domains. This binary is saved to temporary directories under disguised filenames, given executable permissions, and spawned detached via shell commands. There is no hash or signature verification of the binary, and the infrastructure used is not owned by the package publisher. The package's public API is a no-op stub, consistent with a malicious dropper package likely used in dependency confusion or typosquatting attacks. Environment variables related to telemetry are checked as a cover story, and a marker file gates re-execution. The package effectively grants full control of the host to an external entity.
