It derives a host from blockchain data, retrieves code, evaluates it, and launches detached Node processes. - **Trigger:** Importing or requiring the package's CJS or ESM entrypoint. - **Impact:** Arbitrary attacker-controlled code can execute in the importing Node process and persist as detached child processes. - **Evidence paths:** package.json, src/api/client.ts, src/components/modal.ts, src/index.ts, src/voxepay.ts, dist/index.cjs.js, dist/index.esm.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:28:35.950Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated blockchain-addressed remote code execution with detached-process launch. - **Attack narrative:** On import, the appended loader contacts Ethereum RPC/block-explorer services, locates a transaction from a hard-coded address, and interprets transaction bytes as command-host IP addresses. It fetches XOR-obfuscated payloads from those hosts, evaluates one in-process, and starts another with detached node -e execution. This is concealed in built artifacts and absent from reviewed TypeScript source. - **Rationale:** The package contains a concrete, import-time remote-code-execution chain with stealthy second-stage retrieval and detached execution. The legitimate payment SDK source does not account for this appended artifact payload. - **Files touched:** dist/index.cjs.js, dist/index.esm.js - **Network endpoints:** https://1rpc.io/eth, https://eth.drpc.org, https://ethereum-rpc.publicnode.com, https://eth-mainnet.public.blastapi.io, https://eth.blockscout.com/api ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.cjs.js appends obfuscated eval(atob(...)) after exports., Decoded payload runs immediately on module import and requires child\_process., Payload queries Ethereum RPC/block explorers to derive a command host., It fetches XOR-obfuscated second-stage code, evals it, and spawns detached node processes., The same appended loader is present in dist/index.esm.js. - **Evidence against:** src/ contains a conventional browser payment SDK and no matching loader., package.json has only prepublishOnly; no install lifecycle hook. ## Public findings ### 1. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** dist/index.cjs.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern. Public source snippet (untrusted): ```javascript L2270: exports.validateCardNumber = validateCardNumber; L2271: exports.validateExpiry = validateExpiry; ... L2272: //# sourceMappingURL=index.cjs.js.map ``` ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 6. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 65.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepublishOnly - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @voxepay/checkout - **Ecosystem:** npm - **Version:** 0.5.19 - **License:** MIT - **Version published:** 2026-08-05T11:28:35.739Z - **Package first seen:** 2026-08-05T18:28:35.950Z - **Package last seen:** 2026-08-08T13:16:44.194Z - **Known versions:** 9 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Modern payment checkout modal for VoxePay - beautiful, fast, and secure - **Author:** VoxePay - **Keywords:** voxepay, checkout, payment, modal, fintech, nigeria, payment-gateway - **Artifact files:** 24 - **Artifact unpacked size:** 578,963 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]() - [OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
