Malicious code in deposit-limit-fe (npm)

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (89565d767d3541470834dc9764af6e4abbe4acb5ba4eb721f7e3008e3a80b1d2) [email protected] is published as a 'Deposit limit frontend utilities' library but its main entry (index.js) exports an empty object and ships no real functionality. package.json declares `postinstall: node postinstall.js`, which require()s a bundled Linux x64 native addon at `prebuilds/linux-x64/addon.node` inside a silenced try/catch. The addon has no corresponding C/C++ source or binding.gyp in the tarball. On load it reads the environment variables HOSTNAME, USER, npm_package_name, and npm_config_registry, forks, opens a TCP socket to the hardcoded bare IP 64.181.165.115, and sends `POST /dc HTTP/1.0` with a form-encoded body `h=<hostname>&p=<package>&u=<user>&r=<registry>`. The anomalous 100.100.101 version and the explicit exfiltration of `npm_config_registry` are the fingerprint of a dependency-confusion reconnaissance beacon targeting an internal/private npm registry package name. Installing this package automatically leaks the installer's hostname, OS username, and private npm registry URL to an attacker-controlled endpoint and executes opaque native code on the installer's machine.
