It retrieves staged instructions through Ethereum data and executes downloaded code in the host Node process or a detached child. - **Trigger:** Application build, server, or tooling imports react-scroll-disable. - **Impact:** Arbitrary attacker-controlled code execution and persistence outside the intended scroll-control functionality. - **Evidence paths:** package.json, dist/es5/index.js, dist/es2015/index.js, dist/es2019/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:53:32.384Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated blockchain-addressed remote payload loader with eval and detached child-process execution. - **Attack narrative:** Each public entrypoint appends a Base64-obfuscated immediate async loader. It contacts configured/public Ethereum RPC services, locates transaction data, derives further hosts, retrieves an encoded payload, and executes it via eval or a detached \`node -e\` process. This is unrelated to the advertised React scroll utility and runs solely on import. - **Rationale:** Confirmed import-time staged remote code execution in all published entrypoints. The absence of install hooks does not mitigate the concrete runtime execution chain. - **Files touched:** dist/es5/index.js, dist/es2015/index.js, dist/es2019/index.js - **Network endpoints:** https://eth.blockscout.com/api, 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:** All three published entrypoints append obfuscated \`eval(atob(...))\`., Decoded loader runs immediately when the package entrypoint is imported., Loader queries Ethereum RPCs, including \`eth.blockscout.com\` and \`eth-mainnet.public.blastapi.io\`, for staged data., It derives remote hosts, fetches a payload, XOR-decodes it, then executes it with \`eval\` or detached \`node -e\`., \`package.json\` exposes the compromised files as main/module entrypoints. - **Evidence against:** No npm preinstall/install/postinstall hook is declared., The visible React scroll-control modules are package-aligned, but do not constrain the appended loader. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** dist/es5/index.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern.

High: Same File Env Network Execution - **Category:** Source - **Confidence:** 85.0% - **Path:** dist/es5/index.js\#virtual:base64:round1 - **Public source:** [View source]() A single source file combines environment access, network access, and code or shell execution; review context before blocking.
