It obtains command data through Ethereum RPC services and executes downloaded code. - **Trigger:** A consumer imports or loads the package entrypoint. - **Impact:** An attacker can run arbitrary code in the consuming user's Node environment. - **Evidence paths:** src/index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T15:20:41.339Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated network-backed remote code execution - **Attack narrative:** The package entrypoint appends an immediate eval of a Base64-encoded loader. The decoded loader searches Ethereum transaction data for command infrastructure, retrieves a payload over HTTP, then evaluates it directly or starts a detached Node process containing it. This behavior is unrelated to Tailwind animation utilities and gives a remote operator code execution when the package is loaded. - **Rationale:** The package deliberately conceals a remote code loader in its runtime entrypoint. Its network-selected payload execution is concrete malicious behavior. - **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:** The manifest loads src/index.js as the package entrypoint., The entrypoint immediately evaluates a concealed Base64 program., Static decoding shows the concealed program queries Ethereum services for a command location, downloads a payload, and evaluates it or launches it as a detached Node process. - **Evidence against:** package.json has no npm lifecycle hook., The visible Tailwind utility code is consistent with an animation plugin. ## Public findings ### 1.
