It contacts Ethereum RPC/explorer services to resolve a C2 address and executes returned code. - **Trigger:** Importing dist/index.js, including normal Tailwind configuration/build use. - **Impact:** Arbitrary code execution in the importing user's Node environment. - **Evidence paths:** package.json, dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T09:46:50.173Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated import-time C2 discovery and remote code execution - **Attack narrative:** The package entrypoint appends a base64-obfuscated payload after the legitimate plugin export. On import it queries Ethereum RPC/explorer endpoints, derives an IP address from a selected transaction, requests C2 paths, decodes response data, and executes it with eval or a detached node process. This is unrelated to scrollbar styling and gives a remote operator arbitrary execution. - **Rationale:** The source establishes an import-time, obfuscated remote payload chain with direct eval and detached process execution. Absence of npm lifecycle hooks does not mitigate execution when the plugin is imported. - **Files touched:** dist/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:** dist/index.js appends an obfuscated eval(atob(...)) payload to the plugin entrypoint., The decoded payload runs at module import and uses HTTP(S) plus child\_process.spawn., It derives a C2 IP from Ethereum transaction data, then requests /0x/cls and /0x/ls., Remote response/header data is decoded and executed via eval or detached node -e. - **Evidence against:** package.json has no lifecycle hooks., The visible Tailwind utility code is benign, but does not constrain the appended import-time payload. ## Public findings ### 1.
