Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-16353/ (Markdown: https://insights.sbomify.com/MAL-2026-16353/index.md)","id":"MAL-2026-16353","markdown":"https://insights.sbomify.com/MAL-2026-16353/index.md","name":"MAL-2026-16353","record":{"aliases":["GHSA-rjh6-qm48-cg84"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"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.\n\nAny computer that has this package installed or running should be considered fully compromised.
