Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is a concrete, undisclosed import-time remote code execution chain unrelated to a UUID package. The absence of lifecycle hooks does not mitigate the automatic runtime trigger. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-27T09:01:38.880Z - **Finished:** 2026-07-27T09:01:55.757Z - **Download time:** 507 ms - **Static scan time:** 25 ms - **AI review time:** 16344 ms - **Total time:** 16877 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers an undisclosed remote payload chain. It reads a project README, derives a concealed endpoint, fingerprints the host, drops a temporary VBS payload, and executes it. - **Trigger:** Importing or requiring dateuuidv2. - **Impact:** Remote code execution in the importing user's environment. - **Evidence paths:** index.js, index.mjs, lib/bootstrap.js, lib/store.js, README.md, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-27T09:01:55.757Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** concealed endpoint derivation, remote payload download, drop-and-execute - **Attack narrative:** Both public entrypoints load bootstrap code at import time. Bootstrap invokes extractDateISO, which reads the current project's README, uses a PORT value to construct decryption material for a hidden URL, POSTs platform/release data, writes the response to a temporary .vbs file, and executes it. Errors are intentionally swallowed, making the behavior silent. - **Rationale:** This is a concrete, undisclosed import-time remote code execution chain unrelated to a UUID package. The absence of lifecycle hooks does not mitigate the automatic runtime trigger. - **Files touched:** README.md, ${os.tmpdir()}/temp\_\.vbs ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js and index.mjs import lib/bootstrap on every package import., lib/bootstrap.js immediately calls extractDateISO() and suppresses errors., lib/store.js derives and decrypts a concealed URL from the consuming project's README PORT line., lib/store.js POSTs OS/platform data to that URL, writes its response as a temporary .vbs file, then executes it with child\_process.exec., The README documents only UUID functions and does not disclose this import-time behavior. - **Evidence against:** package.json has no npm lifecycle scripts., UUID generation and parsing functions are otherwise conventional. ## Affected versions and remediation This report applies to dateuuidv2@1.0.1. - Avoid installing dateuuidv2@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** lib/store.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L60: L61: const { exec } = require('child_process'); L62: const fs = require('fs/promises'); ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Critical: Remote Asset Decode Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** lib/store.js - **Public source:** [View source]() Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload. Public source snippet (untrusted): ```javascript L60: L61: const { exec } = require('child_process'); L62: const fs = require('fs/promises'); ... L117: async function readApiFromReadme( L118: projectRoot = process.cwd(), L119: ) { ...

L192: async function fetchString(url) { L193: const response = await fetch(url, { L194: method: "POST", ``` ### 5. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** lib/store.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.exports -> lib/store.js Reachable file contains a blocking source-risk pattern. ``` ### 6. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## 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:** dateuuidv2 - **Ecosystem:** npm - **Version:** 1.0.1 - **License:** MIT - **Version published:** 2026-07-26T11:59:52.204Z - **Package first seen:** 2026-07-27T08:59:36.560Z - **Package last seen:** 2026-07-27T09:01:55.757Z - **Known versions:** 2 - **Latest version:** 1.0.1 - **Appeal under review:** No - **Description:** Generates a UUID based on the current date and time. - **Author:** jinwoochoi - **Keywords:** backend, uuid, date - **Runtime engines:** node: \>=18 - **Artifact files:** 6 - **Artifact unpacked size:** 9,487 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
