MAL-2026-16345 Malicious code in starbucks-sdk (npm)

The package's package.json declares a preinstall script that runs callback.js on npm install. callback.js collects os.hostname(), os.userInfo(), os.platform(), the current working directory, and a timestamp, then enumerates process.env and selects keys matching /token|secret|key|pass|auth|api|aws/i (up to 10 entries). The collected data is POSTed via https.request to https://api.telegram.org/bot<BOT_TOKEN>/sendMessage using a hardcoded Telegram bot token and chat_id (bot 8636277735, chat_id 1064260758). The name mimics a legitimate vendor SDK but the package's only behavior is install-time reconnaissance and exfiltration of installer/build-host identity and credential-shaped environment variable names to an attacker-controlled Telegram channel — a dependency-confusion recon payload.

The OpenSSF Package Analysis project identified 'starbucks-sdk' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
