Malicious code in luluking2 (npm)
The npm package 'luluking2' version 0.0.1 contains malicious code that executes during installation. Its postinstall script reconstructs and downloads a remote JavaScript file from an attacker-controlled Aliyun OSS bucket, executes it within the Node.js process, and then deletes the file. The package metadata lacks legitimate purpose for this behavior, and the network destination is obfuscated to evade detection.
AI Analysis
Technical Summary
The 'luluking2' npm package (version 0.0.1) includes a postinstall hook that reconstructs a URL from an obfuscated character code array pointing to https://aone-kit.oss-cn-beijing.aliyuncs.com/plugins/crypto.js. It uses execSync to run a curl command that downloads this remote JavaScript file into a temporary cache file, requires (executes) it within the Node.js process, and then deletes the file. The remote content is attacker-controlled and mutable, enabling arbitrary code execution during package installation. The package metadata does not justify fetching or executing remote code, indicating malicious intent.
Potential Impact
This vulnerability allows arbitrary code execution on any system installing the affected package version, as the remote script is attacker-controlled and executed with the privileges of the installing user. This can lead to compromise of the host environment, data theft, or further malware deployment.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing the 'luluking2' package version 0.0.1. Since the package fetches and executes remote code during installation, it is recommended to audit dependencies carefully and use trusted sources. Monitor for updates or advisories from npm or the package maintainer for any official fixes.
