Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Install and import of the package main entry run an obfuscated DNS lookup that embeds the local username, hostname, and directory name in a query to oob.algamil7x.xyz. Comments describe a registry connectivity check, but the encoded destination is an unrelated host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-22T17:00:51.158Z - **Finished:** 2026-09-22T17:02:50.672Z - **Download time:** 507 ms - **Static scan time:** 43 ms - **AI review time:** 118963 ms - **Total time:** 119514 ms The recorded confidence comes from the underlying analysis.

Comments describe a registry connectivity check, but the encoded destination is an unrelated host. - **Trigger:** npm install executes node index.js, and any require of the package main also runs the same bootstrap. - **Impact:** Host identity and project-directory name are disclosed to the operator of oob.algamil7x.xyz through DNS queries during install or import. - **Evidence paths:** package.json, index.js, runtime/index.js, runtime/support/telemetry/index.js, runtime/support/telemetry/probe/index.js, runtime/support/telemetry/probe/impl.js, runtime/support/telemetry/probe/b8d6e3.js, runtime/support/telemetry/probe/c9e7f4.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T17:02:50.672Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bootstrap starts telemetry, which loads impl.js. That file collects os.userInfo().username, os.hostname(), and the current directory basename, then calls dns.resolve4 with labels prefixed by uswc and suffixed by oob.algamil7x.xyz. - **Attack narrative:** On npm install, the install script runs index.js, which calls the runtime bootstrap. That path starts telemetry and loads probe/impl.js. The probe immediately reads the username, hostname, and current directory name, hex-decodes os, dns, and resolve4, and issues a DNS A lookup whose labels carry those values to oob.algamil7x.xyz. Importing the package repeats the same lookup. Errors are swallowed so install still succeeds. - **Rationale:** The install hook and package entry load obfuscated code that DNS-exfiltrates host and directory identity to oob.algamil7x.xyz. The web-component exports do not account for that hidden lookup or its unrelated destination. - **Network endpoints:** oob.algamil7x.xyz ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** npm install runs node index.js through the install lifecycle script., Loading the package entry immediately calls the runtime bootstrap and hides errors., Bootstrap starts telemetry, which loads the probe module and therefore impl.js., impl.js reads the username, hostname, and current directory name, then calls dns.resolve4 on a joined label string., Obfuscated helpers load the os and dns modules through module.constructor.\_load and sanitize values to short alphanumeric labels., Decoded constants set the query prefix uswc and the recipient domain oob.algamil7x.xyz. - **Evidence against:** src/index.js only re-exports component, session, page, and OIDC helper functions., The package has no child\_process usage and does not install another copy of itself. ## Affected versions and remediation This report applies to @user-services/web-components@9.9.10. - Avoid installing @user-services/web-components@9.9.10. 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.
