Summary
Malicious code in @insiderintelligence/componentlibrary (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (a4451c41559202c6bce3218de9af47cabe20288af5f3a9240076f25b3b2b5993)

The package declares scripts.install: node index.js, so npm install auto-executes index.js which loads runtime/support/telemetry/probe/impl.js. That module reads os.userInfo().username, os.hostname(), and the current working directory's leaf name, joins them with a fixed prefix (iiclib) and a timestamp into a subdomain label, and issues a dns.resolve4() query against oob.algamil7x.xyz — exfiltrating installer identity via a DNS side-channel that bypasses HTTP egress controls. The destination host, the module names ('os','dns','process'), and the resolved API names ('userInfo','hostname','cwd','resolve4','_load') are hidden behind String.fromCharCode arrays in sibling helpers a8e4c9.js and f7d3b8.js, and the module is loaded via module.constructor._load through encoded literals to disguise the primitive as a 'connectivity probe'. The same path also runs on require() because index.js is the package main. The behavior has no connection to the package's stated component-library purpose.

Any computer that has this package installed or running should be considered fully compromised. 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.
