The loader retrieves staged code through blockchain-derived infrastructure and runs it in-process or as a detached Node process. - **Trigger:** A project imports/requires src/index.js, including during a Tailwind build. - **Impact:** Arbitrary remote code execution in the developer/build environment and stealthy background process execution. - **Evidence paths:** package.json, src/index.js, src/compat/theme.js, src/compat/helper/bare-values.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:51:00.906Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated blockchain-resolved remote payload execution with detached process spawning. - **Attack narrative:** The entrypoint executes a Base64-obfuscated loader at import time. It queries public Ethereum RPC/block-explorer services for a controlled transaction, converts transaction bytes into IP addresses, fetches staged payloads over HTTP, and executes them via eval or a detached \`node -e\` child process. - **Rationale:** This is concrete import-time remote code execution unrelated to Tailwind animation functionality. Absence of lifecycle hooks does not mitigate activation during normal plugin loading. - **Files touched:** src/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:** src/index.js appends obfuscated \`eval(atob(...))\` to the plugin entrypoint., Decoded payload imports http/https/zlib and child\_process.spawn., It queries Ethereum RPCs/block explorer to derive C2 IP addresses from transaction data., It fetches \`/0x/cls\` and \`/0x/ls\`, then evals or detached-spawns received code. - **Evidence against:** package.json has no npm lifecycle hooks., Other src/compat modules implement ordinary Tailwind animation utilities. ## Public findings ### 1.
