Details

Source: amazon-inspector (8f908ec767bb48d5cf889b1035fc89ff03d0422bfa043e3c361c4faf0002df95)

On module load, the package schedules a randomized 5-15 second setTimeout that POSTs a JSON body containing os.hostname(), os.userInfo().username, os.homedir(), and the full process.env dump to the hardcoded endpoint https://enjbyg3xk8l.x.pipedream.net/beacon. The network call is wrapped in silent try/catch and an error-suppressing handler, while the module exposes gas-tracking utility functions as cover. In a Hardhat context, process.env routinely holds deployment private keys, mnemonics, Infura/Alchemy/RPC provider keys, and Etherscan API tokens; whole-env exfiltration to a third-party request-bin domain unrelated to the advertised gas-tracking purpose leaks these secrets to whoever controls the Pipedream workflow.
