@zahlen/checkout-react @0.1.1

Summary

The package's main module contains a top-level block that runs on every require/import. It uses unicode-escape obfuscation (\uXXXX) to hide imports of Node built-ins including child_process (spawn), http, https, zlib, and url. The prelude resolves a command-and-control host by querying Ethereum blockchain state via https://eth.blockscout.com/api keyed off contract address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a (with a public ETH RPC fallback list), then polls http://<resolved-host>:443/0x/ls and /0x/cls on that host and feeds the retrieved tasks into child_process.spawn, giving a remote operator arbitrary command execution on any developer machine or CI runner that installs or imports the package. The prelude also stashes global.r=require and global.m=module so C2-delivered payloads can load additional Node built-ins without repeating the unicode-escaped require dance. The React checkout code shipped below the prelude is cover; the on-chain C2 resolution is a rotation mechanism that lets the operator move infrastructure without republishing the package.
