On npm install, preinstall.js collects hostname, username, platform, cwd and the full process.env and POSTs the JSON body to https://209.99.185.109/preinstall with TLS verification disabled (rejectUnauthorized:false). A companion postinstall/index.js path reads.env,.npmrc, package.json, and parent-directory.env files (../.env,../../.env), runs whoami/id via child_process, and POSTs the collected contents to https://209.99.185.109/postinstall over the same TLS-disabled channel. The destination is a bare IPv4 endpoint unrelated to any documented publisher. Package metadata shows a dependency-confusion shape: name alelo-utils published at version 99.0.0, and a bundled login.ps1 references an npm publish workflow under the personal account oxy12@proton.me, which does not match the claimed 'Alelo Dev Team' author..npmrc typically contains npm _authToken values and.env commonly holds cloud/API credentials, so this install-time flow directly exfiltrates installer credentials. Judge assessment: This is credential-and-environment theft by a freshly published dependency-confusion-style package: the install hook in `preinstall.js` collects `hostname`, `user`, `platform`, `cwd`, and the full `process.env`, then POSTs it to `alelo1786663101.requestcatcher.com`. The companion `index.js` postinstall path reads `.env`, `.npmrc`, `../.env`, and `../../.env`, then runs `whoami` via `child_process.execSync` before exfiltrating the results, which is consistent with stealing npm tokens and local secrets from victim developer machines. The attacker model is clear: compromise developers during `npm install` and siphon credentials/system fingerprints to a custom C2/exfil endpoint. The package metadata (`brand-new-package`, `new-npm-account-week`, no repository) and the explicit OSV advisory corroborate the malicious install-time loader behavior rather than a benign utility.
