Advisory PublishedCVSS 8.8/10
The package auto-executes exfiltration code during npm install via preinstall and postinstall lifecycle scripts. preinstall.js collects the hostname, username, platform, cwd, and the full process.env, then POSTs the JSON payload to https://209.99.185.109/preinstall with TLS certificate validation disabled (rejectUnauthorized: false). index.js (postinstall) reads.env,.npmrc, package.json,../.env, and../../.env from the install directory, runs whoami and id, gathers process.env, and POSTs the aggregated payload to https://209.99.185.109/postinstall over the same TLS-disabled channel. The.npmrc read captures the installer's npm _authToken; the.env reads capture cloud, database, and API credentials. The destination is a bare-IP endpoint with no relationship to any legitimate publisher, and TLS verification is deliberately disabled. The package name resembles a private/internal scope, consistent with a dependency-confusion lure.
Judge assessment: This is a clear credential-theft and environment-exfiltration installer implant aimed at npm users or CI pipelines that install the package. The `preinstall.js` entrypoint is executed via `package.json` scripts and immediately POSTs `process.env`, hostname, username, platform, and cwd to `alelo1786663101.requestcatcher.com/preinstall`, while `index.js` does the same on postinstall and also reads `.env`, `.npmrc`, `../.env`, and `../../.env` before sending them out. The use of `requestcatcher.com` as an exfil/C2 destination, plus `child_process.execSync('whoami')`, shows an attacker model of dependency-confusion or typosquat delivery harvesting secrets from the install environment. The very new publisher account and brand-new package metadata further support malicious intent rather than a legitimate utility.
