@biz44/id12-client@1.1.13
Malicious code in @biz44/id12-client (npm)
Analysis
@biz44/id12-client@1.1.13 is a remote-code-execution dropper. Importing the package auto-spawns a detached background `node loader.js` process (persisted via a .pid file). loader.js fetches a JSON payload from hxxps://api[.]npoint[.]io/24c12c4b66a29747764f, base64-decodes the `code` field, and executes it with full require/module access via the Function constructor, giving the remote server arbitrary code execution on the host. It also monkey-patches Module.prototype.require to intercept child_process calls. The malicious second stage is served remotely from npoint[.]io rather than shipped in the package.
