🛡️ MAL-2026-12398 — luluking2

Malicious code in luluking2 (npm)

Source: amazon-inspector

On npm install, the package's postinstall hook runs index.js, which reconstructs a URL from a char-code array (String.fromCharCode.apply on a numeric literal array with _0x-prefixed identifiers) resolving to https://aone-kit.oss-cn-beijing.aliyuncs.com/plugins/crypto.js. It shells out via execSync to curl -sL -o ".cache" "<url>", then require()s the downloaded file and deletes it. The destination URL, the filename, and the curl command string are all obfuscated via char-code reconstruction to hide the network destination from source inspection. The remote content is attacker-mutable (an Aliyun OSS bucket) and is executed inside the installing Node process on every install. Package metadata is placeholder-level with no legitimate declared purpose that would justify fetching and executing remote code at install time.
