Summary
On npm install , the postinstall hook requires src/index.js, which enumerates a hardcoded list of crypto wallet files, SSH private keys, and environment/mnemonic files in the user's home and current working directory (including ~/.ssh/id_rsa , ~/.config/solana/id.json , .env , and seed/mnemonic files for Solana, Ethereum, Bitcoin, Tron, Sui, and Aptos). The collected file contents are POSTed to api.telegram.org using a hardcoded bot token ( 8227918239:AAGE... ) and chat ID ( 6433587894 ). The payload self-identifies as <b>CRYPTO STEALER</b> in the Telegram message body. Execution is gated by an isTestEnvironment() check at src/index.js:11-26 that suppresses the payload in CI, GitHub Actions, Jenkins, Docker, and sandbox-shaped hostnames/usernames — analysis-evasion to keep the stealer dormant during scanning and active on developer workstations. The package ships no legitimate functionality; the generic name defi-tools-39 with a bland 'Cryptocurrency wallet management toolkit' description targets developers searching for DeFi/wallet tooling — the cohort most likely to have on-disk wallet keypairs.
