It retrieves and runs attacker-controlled code from dynamically derived HTTP hosts. - **Trigger:** Any runtime require/import of build/index.js. - **Impact:** Remote code execution in the importing application's process context, with detached follow-on execution. - **Evidence paths:** package.json, build/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:30:42.691Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated import-time remote payload loader and detached Node execution. - **Attack narrative:** The package entrypoint contains an obfuscated payload that runs whenever the module is imported. It queries public Ethereum endpoints to derive command-and-control IP addresses from transaction bytes, downloads XOR-obfuscated code over HTTP, evaluates it, and spawns a detached Node process to run it. This is a concealed remote-code loader unrelated to the package's stated middleware/event functionality. - **Rationale:** Direct source inspection confirms a concealed, import-time remote payload execution chain. The absence of lifecycle hooks does not mitigate runtime compromise when consumers import the package. - **Files touched:** build/index.js - **Network endpoints:** https://eth.blockscout.com/api, https://1rpc.io/eth, https://eth.drpc.org, https://ethereum-rpc.publicnode.com, https://eth-mainnet.public.blastapi.io ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** build/index.js appends an obfuscated immediate eval(atob(...)) payload., Decoded payload runs on module import and queries Ethereum RPC/block-explorer services., It derives HTTP hosts from an on-chain transaction, fetches XOR-obfuscated content, then evals it., It also launches fetched code detached via child\_process.spawn('node',\['-e',...\]). - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The normal exports are common middleware/event utilities, but the appended payload is unrelated. ## Public findings ### 1.
