Unconsented installation can alter broad local AI-agent control surfaces and establish persistence through an uninspected binary. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package fetches an opaque native binary and automatically runs its setup action. That action is described as registering with whichever supported agent harnesses exist and starting a background process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T03:21:15.701Z - **Finished:** 2026-09-15T03:22:13.179Z - **Download time:** 772 ms - **Static scan time:** 404 ms - **AI review time:** 56301 ms - **Total time:** 57478 ms The recorded confidence comes from the underlying analysis.

That action is described as registering with whichever supported agent harnesses exist and starting a background process. - **Trigger:** npm postinstall - **Impact:** Unconsented installation can alter broad local AI-agent control surfaces and establish persistence through an uninspected binary. - **Evidence paths:** package.json, postinstall.mjs, lib/launcher.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-15T03:22:13.179Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download followed by automatic agent-harness setup and background-process registration - **Attack narrative:** On npm installation, postinstall invokes the launcher. It downloads a platform-specific binary from packages.opscanvas.io, writes it as bin/opscanvas, and executes it with setup. The package states that setup registers with whichever supported agent harnesses are present and starts a background process, making this an automatic, broad agent-control and persistence action performed by opaque native code. - **Rationale:** This is an unconsented postinstall path that downloads and executes opaque code to register across available agent harnesses and start a background process. Checksum verification limits replacement in transit but does not make the package-authored binary or its broad automatic setup safe. - **Files touched:** package.json, postinstall.mjs, lib/launcher.js, bin/opscanvas - **Network endpoints:** packages.opscanvas.io ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically runs the launcher., The launcher downloads a platform binary and executes its setup command during installation., The package declares remote binary URLs for every supported platform., The supplied documentation says installation registers supported agent harnesses and starts a background process., The postinstall module imports and invokes the launcher postinstall function. - **Evidence against:** The downloader verifies the downloaded binary against a manifest SHA-256 before executing it., The visible JavaScript does not harvest files or secrets. ## Affected versions and remediation This report applies to @opscanvas/opscanvas@0.1.0. - Avoid installing @opscanvas/opscanvas@0.1.0. 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.
