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. Obfuscated browser scripts replace payment-page behavior and redirect a user-submitted deposit flow to an external payment host. The package does not install or import them automatically, but executing any payload in the intended page activates the behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-11T08:12:56.028Z - **Finished:** 2026-09-11T08:14:31.436Z - **Download time:** 256 ms - **Static scan time:** 82 ms - **AI review time:** 95070 ms - **Total time:** 95408 ms The recorded confidence comes from the underlying analysis.

The package does not install or import them automatically, but executing any payload in the intended page activates the behavior. - **Trigger:** A host page loads one of the bundled scripts and the user submits the added deposit form. - **Impact:** A user can be steered to an attacker-controlled payment flow with their account identifier and transaction details. - **Evidence paths:** cnn303\_v27a93d2f8c1e5b64a9d0f27c4e8b1a6d3f5c9e2a7b4d8f1c6e0a5b3d9f2c7e.js, k333\_7a93d22a499f0a5e89d257ea5e68ca7d25e1265f319c1c1a.js, mr3\_f5b83a1d9c7e2046a8d3f6c2b1e9a047d5c8f2b6a3e1d9c4.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T08:14:31.436Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated payment-flow injection that harvests page data and redirects it externally. - **Attack narrative:** When one of the bundled browser payloads is inserted into its targeted deposit page, it removes existing QR payment options, adds its own deposit option, obtains the page's member username, and builds an encrypted record containing the username, amount, reference, and return URL. Clicking the injected submit button changes the browser location to payment.meta-engine.dev with that encrypted record. The three payloads are branded variants of the same behavior. - **Rationale:** This is concrete, obfuscated payment-flow hijacking and external data transfer, even though it is not automatically run by npm installation. The missing declared entrypoint further suggests the package is a carrier for scripts meant to be injected elsewhere. - **Files touched:** cnn303\_v27a93d2f8c1e5b64a9d0f27c4e8b1a6d3f5c9e2a7b4d8f1c6e0a5b3d9f2c7e.js, k333\_7a93d22a499f0a5e89d257ea5e68ca7d25e1265f319c1c1a.js, mr3\_f5b83a1d9c7e2046a8d3f6c2b1e9a047d5c8f2b6a3e1d9c4.js - **Network endpoints:** https://payment.meta-engine.dev/sdk/client.html?d= ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** All three bundled scripts are deliberately obfuscated browser payloads., The payloads alter deposit-page controls and collect the displayed member username, entered amount, and current return URL., On a user deposit action, they encrypt those values and redirect the browser to payment.meta-engine.dev., The manifest points to a missing index.js, leaving the harmful scripts unreferenced by normal package loading., This script embeds the payment.meta-engine.dev client endpoint., This script embeds the payment.meta-engine.dev client endpoint., This script embeds the payment.meta-engine.dev client endpoint. - **Evidence against:** There are no npm lifecycle hooks., No Node child-process, filesystem, or environment access was found., The browser redirect requires the script to be loaded and a user to submit a deposit. ## Affected versions and remediation This report applies to slider-script@1.0.0. - Avoid installing slider-script@1.0.0. 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.
