What to do

Remove @baanx/blockchain-config 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 '@baanx/blockchain-config' version 9.9.11 contains malicious code that executes automatically during installation and when required. It performs an obfuscated probe that collects system information including the username, hostname, and current working directory, then exfiltrates this data via DNS queries to an external domain unrelated to the legitimate publisher. This behavior indicates a compromise of any system where the package is installed, potentially exposing all stored secrets and keys.

Impact

Any system with this package installed or running is considered fully compromised. The malicious code exfiltrates sensitive system identity information to an attacker-controlled domain, potentially allowing unauthorized access or further exploitation. All secrets and keys stored on the compromised system should be considered exposed and must be rotated immediately from a secure, unaffected environment. Removal of the package alone does not guarantee elimination of all malicious artifacts or backdoors.

Defensive guidance

Immediate removal of the '@baanx/blockchain-config' package version 9.9.11 is required. All secrets, credentials, and keys stored on the affected system should be rotated from a different, trusted machine. Due to the full compromise risk, a thorough system investigation and remediation are recommended.

Summary

The '@baanx/blockchain-config' npm package version 9.9.11 includes malicious code embedded in obfuscated scripts that run during the install lifecycle and module loading. The code collects sensitive system information such as os.userInfo().username, os.hostname(), and the basename of process.cwd(), concatenates these with a static tag and a timestamp, and sends this data via DNS resolution requests to a non-affiliated external domain 'oob.algamil7x.xyz'. The obfuscation uses hex-decoded byte arrays and dynamic module loading to evade static analysis. This exfiltration occurs automatically on 'npm install' and on requiring the package, indicating a supply chain compromise.
