Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — May bias a reviewer toward dismissing potential concerns without independently checking the source. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.0.0-next.421 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The inspected runtime behavior fits a VS Code data-client, but the manifest contains review-directed reassurance about lifecycle safety that appears intended to influence the verdict. I treated that reviewer manipulation as malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-04T11:52:26.359Z - **Finished:** 2026-11-04T11:53:08.876Z - **Download time:** 510 ms - **Static scan time:** 78 ms - **AI review time:** 41929 ms - **Total time:** 42517 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:** Review manipulation in package metadata; no operational attack behavior was identified in the inspected runtime code. - **Trigger:** Security review of package.json. - **Impact:** May bias a reviewer toward dismissing potential concerns without independently checking the source. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-11-04T11:53:08.876Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Manifest commentary makes strong reassuring claims about lifecycle behavior and publishing safety. - **Attack narrative:** The manifest includes unusually emphatic assurances that its prepack hook cannot affect installation and that publication is safe. This appears intended to steer review; the inspected runtime code otherwise implements the documented local socket and webview relay. - **Rationale:** The inspected runtime behavior fits a VS Code data-client, but the manifest contains review-directed reassurance about lifecycle safety that appears intended to influence the verdict. I treated that reviewer manipulation as malicious intent. - **Files touched:** package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 84.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest contains unusually persuasive commentary asserting the prepack hook “cannot break the install” and describing the package as safe to publish, which appears aimed at steering security review. - **Evidence against:** The declared scripts are build, cleanup, lint, tests, watch, and a prepack guard; no install lifecycle hook is declared., The inspected socket code connects to 127.0.0.1 by default, and the messenger code relays notifications between the extension host and its webview. ## Affected versions and remediation This report applies to @hydranium/data-client-vscode@1.0.0-next.421. - Avoid installing @hydranium/data-client-vscode@1.0.0-next.421. 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 84.0% - **Path:** package.json - **Public source:** [View source]() The manifest contains unusually persuasive commentary asserting the prepack hook “cannot break the install” and describing the package as safe to publish, which appears aimed at steering security review. Public source snippet (untrusted): ```json "//prepack": "The publish guard, a `prepack` rather than a `prepare`: `prepack` runs only when a tarball is made (`npm pack`, `npm publish`) and never on install, so it cannot break the install it has no business touching. What it defends against: `files` lists `lib`, `lib` is gitignored, and a `files` entry matching nothing is skipped SILENTLY — so `npm publish` from an unbuilt tree emits a tarball of `src` and nothing else, with no error.", ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 5 - **Development dependencies:** 9 - **Published dependency-graph edges:** 5 ### Published dependency entries - @hydranium/protocol 1.0.0-next.421 (PeerDependency) - vscode-jsonrpc ^9.0.3 (PeerDependency) - vscode-messenger ^0.4.5 (PeerDependency) - vscode-messenger-common ^0.4.5 (PeerDependency) - vscode-messenger-webview ^0.4.5 (PeerDependency) ## Package metadata - **Package:** @hydranium/data-client-vscode - **Ecosystem:** npm - **Version:** 1.0.0-next.421 - **License:** MIT - **Version published:** 2026-11-04T11:48:52.798Z - **Package first seen:** 2026-10-14T23:37:35.865Z - **Package last seen:** 2026-11-04T11:53:08.876Z - **Known versions:** 68 - **Latest version:** 1.0.0-next.421 - **Appeal under review:** No - **Description:** VS Code client primitives for the hydranium data-server protocol head; companion of @hydranium/data-server.
