It discovers a dynamic host through Ethereum RPC, fetches a payload, and executes it in-process or as a detached Node child. - **Trigger:** Importing or loading src/index.js through the package main entrypoint. - **Impact:** Arbitrary code execution under the consuming process user. - **Evidence paths:** package.json, src/index.js, src/compat/helper/bare-values.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:51:05.634Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated import-time remote payload retrieval and eval/spawn execution. - **Attack narrative:** src/index.js executes an encoded loader at import time. The decoded code queries Ethereum RPC services, derives a dynamic server address from transaction data, fetches payloads from /0x/cls and /0x/ls, and executes returned content with eval or a detached node -e process. This is an active remote-code-execution backdoor hidden after legitimate plugin code. - **Rationale:** The package contains concrete, obfuscated import-time payload delivery and execution behavior unrelated to its stated Tailwind functionality. Absence of lifecycle hooks does not mitigate execution through the main entrypoint. - **Files touched:** src/index.js - **Network endpoints:** 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 main entrypoint., Decoded loader runs automatically when the package is imported., Loader queries Ethereum RPC endpoints to derive a dynamic payload host., It fetches /0x/cls and /0x/ls then evals the response or spawns detached node -e., Remote payload execution is unrelated to Tailwind animation utilities. - **Evidence against:** package.json has no npm lifecycle hooks., Other src/compat files implement ordinary Tailwind animation utilities. ## Public findings ### 1.
