**Severity:** Critical

**Affected versions:** `= 99.0.1`

## Source: amazon-inspector (cc4615498b50aa4b5f39a8367c44e6a18d4a7272ae71235716a152b2933d5ddd)
The package is described as a 'Compatibility shim' and ships a stub Proxy-based main plus beacon.cjs. The package.json declares scripts.postinstall: 'node beacon.cjs', and the main entry also invokes the same fire() routine on require. On both triggers, beacon.cjs collects installer identifiers — os.hostname(), __dirname (install path), process.cwd(), process.version, and the package name — and POSTs them in cleartext to the hardcoded bare-IP endpoint http://185.158.107.175:8787/_ah/dc. The destination is not a registry, publisher, or any documented infrastructure; it is a plain-HTTP bare IP with no TLS. An inline source comment states that a build that completes and calls back is cleaner evidence, confirming the artifact's purpose is to signal successful resolution and execution on installer machines. Combined with a scoped name resembling an internal namespace and no real library functionality, this matches the dependency-confusion / namesquat callback-probe shape.
