It resolves a server address through blockchain data, downloads an obfuscated payload, and evaluates it. - **Trigger:** Any build or runtime action that imports/requires fluid-type-ui. - **Impact:** Attacker-controlled arbitrary JavaScript execution in the importing user's Node process. - **Evidence paths:** src/index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-29T09:06:56.230Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote staged payload download, XOR decode, and eval at import time. - **Attack narrative:** The package’s main entrypoint contains concealed code appended after its legitimate Tailwind plugin export. On import it obtains blockchain transaction data to derive a host, fetches an obfuscated payload from /0x/ls, XOR-decodes it, and evaluates it. This makes remote code execution attacker-controlled and reachable whenever consumers load the package. - **Rationale:** This is concrete import-time staged remote code execution, not a package-aligned feature. The absence of lifecycle hooks does not mitigate the reachable malicious entrypoint. - **Files touched:** src/index.js, package.json - **Network endpoints:** https://1rpc.io/eth, https://eth.drpc.org, https://eth.blockscout.com/api?module=account&action=txlist ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** src/index.js appends an immediately invoked async payload after normal plugin code., Import-time code queries Ethereum RPCs and Blockscout to derive a payload host., It fetches /0x/ls, XOR-decodes the response, then calls eval()., No lifecycle hook is needed: requiring the main entrypoint triggers it. - **Evidence against:** package.json has no preinstall/install/postinstall hooks., Other src utilities only implement Tailwind fluid typography helpers. ## Public findings ### 1.
