Malicious code in @or-sdk/notifications (npm)
T1059.007 · JavaScriptT1105 · Ingress Tool TransferT1027 · Obfuscated Files or Information
Analysis
The package runs a preinstall hook (setup.mjs) that downloads the Bun runtime and uses it to execute a bundled 727KB obfuscated script (math_init.js). The script is obfuscated with a large encoded string array and a custom decoder, and contains eval, Function-constructor, and child_process calls. Installing the package triggers remote runtime download and execution of this obfuscated payload at install time.
