alelo-sdk@99.0.0 ships lifecycle scripts that harvest installer data and POST it to a hardcoded bare-IP endpoint (209.99.185.109) with TLS certificate verification disabled. preinstall.js collects hostname, username, platform, cwd, and the full process.env and sends the JSON to https://209.99.185.109/preinstall. The postinstall path (index.js) additionally reads.env,.npmrc, and parent-directory.env files, executes whoami/id, and POSTs the collected content to https://209.99.185.109/postinstall..npmrc typically contains npm publish tokens and.env files typically contain cloud and API credentials, so any environment where this package is installed (developer workstation or CI) has its secrets extracted. Package metadata (name 'alelo-sdk', version 99.0.0, description 'internal utilities', author 'Alelo Dev Team') is the canonical dependency-confusion shape targeting a private 'alelo' internal scope with an inflated version number. Judge assessment: This package is a credential and environment exfiltration loader for a dependency-confusion attacker targeting developer workstations and CI. The install hook in `package.json` runs `preinstall.js` and `index.js`, and those files collect `process.env`, hostname, username, cwd, and even read `.env` and `.npmrc` before POSTing to `alelo1786663101.requestcatcher.com`. The use of `child_process.execSync('whoami')` plus the hardcoded `requestcatcher.com` endpoint and `preinstall`/`postinstall` lifecycle scripts matches the OSV advisory and shows clear theft intent, not a legitimate internal utility. The attacker model is a malicious publisher abusing a public npm package named like a private Alelo SDK to steal secrets from anyone who installs it.
