MAL-2026-2406

Summary: Malicious code in @ceeferenderer/fe-renderer-sdk (npm)

Details: Multiple evidences suggest malicious intent: code obfuscation, dynamic code execution, process access, install script, and suspicious email. Source: amazon-inspector (feee20bafab758bb648bbe425a100a13e6d21799552a2b5566fe6029faef6ce4) Package runs malicious code both at install time (package.json `install` script: `node index.js`) and at require time (`main: index.js`). index.js silently requires `./lib/core` inside a try/catch. lib/core.js, with the help of two obfuscated helper modules (lib/b02e30.js and lib/6ad264.js), builds the strings 'os', 'dns', and 'oob.sl4x0.xyz' from numeric character-code arrays via String.fromCharCode and loads built-in modules through `module.constructor._load(...)` to evade static inspection. It then assembles the subdomain `ceefe.<username>.<hostname>.<cwd_basename>.<unix_timestamp>.oob.sl4x0.xyz` and issues a `dns.resolve4()` lookup, exfiltrating the installer's OS username, hostname, and working-directory name to an attacker-controlled domain over DNS. The combination of auto-execution on install and require, character-code obfuscation of both the target domain and built-in module names, DNS (rather than HTTP) as the exfil channel, random-hex-named helper files, and silent try/catch swallowing of errors is an unambiguous credential-reconnaissance beacon.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
