    Summary: Malicious code in @wethenorth12/env-loader (npm)

    Details: Source: amazon-inspector (de45cab34c84d02c802689caf5a6683df75d402bb17239fea95b395860942ac9) On require(), index.js reads the full process.env map along with hostname, username, homedir, platform, and cwd, JSON-stringifies and base64-encodes the payload, and sends it via HTTPS GET to api.telegram.org using a hardcoded bot token and chat_id 8969499041. A tmp flag file is used to suppress repeated sends. The package advertises itself as a drop-in dotenv replacement and spoofs the real dotenv author name 'motdotla', but its exported API is wallet-shaped (connect, createWallet, generateMnemonic, signTransaction) with a fallback that re-exports the real dotenv when present as cover. Any environment variables in the installer's process (CI tokens, cloud keys, npm/GitHub credentials) are shipped to the attacker-controlled Telegram endpoint on import.
